D:

Daily liveweight gain: The live weight gain of an animal divided by the number of days between two weighings.

Dairy and Tobacco Adjustment Act of 1983 (P.L. 98-180): Signed into law November 29, 1983. The law froze tobacco price-supports, launched a voluntary dairy diversion program, and established a dairy promotion program. The law abolished leasing of quota for flue-cured tobacco beginning in 1987. See Dairy Production Stabilization Act of 1983.

Dairy assessment(s): Under authority of the Agriculture Act of 1949 (Sec. 204), as amended by the Omnibus Budget Reconciliation Act of 1990 and the Omnibus Reconciliation Act of 1993, assessments were authorized for the calendar years 1991 through 1997 to reduce price-support program costs for excess milk equivalent purchases. A refund provision was provided and the program was eventually repealed by the Federal Agriculture Improvement and Reform Act of 1996 (Sec. 141 (g)). See Dairy Refund Payment Program (DRPP).

Dairy cattle breeds: In the U.S. these include the Aryshire, Brown Swiss, Dutch Belted, Guernsey, Holstein (-Friesian), Jersey, Kerry, Lineback, Milking Devon, and Milking Shorthorn.

Dairy compacts: Proposed regional marketing arrangements used to regulate the minimum price for fluid milk above the price established by federal milk marketing orders. The Northeast Interstate Dairy Compact was approved by Congress in 1996 and included Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. Six states were awaiting Congressional or state action to join this compact: New York, New Jersey, Pennsylvania, Delaware, Maryland, and Ohio. A Southern Dairy Compact was also formed although it still needed Congressional approval. Other compacts under consideration were a midwest compact, an inter-mountain compact, and a Pacific compact. The push for the creation of dairy compacts was blunted by the adoption of the National Dairy Market Loss Payment Program in the Farm Security and Rural Investment Act of 2002.

Dairy Export Incentive Program (DEIP): A program first authorized by the Food Security Act of 1985 that offered subsidies to exporters of U.S. dairy products to help them compete with other subsidizing nations. Payments were made by the Commodity Credit Corporation, on a bid basis, either in cash, in-kind, or through certificates redeemable for commodities. The payment rates reflected the type of dairy products exported, the domestic and world prices of dairy products, and other factors. Eligible sales had to be in addition to, and not in place of, those that would normally be made, and payments could not displace commercial export sales. The program was reactivated in 1997. The program authorization was extended until 2002 by the Federal Agriculture Improvement and Reform Act of 1996 and until 2007 by the Farm Security and Rural Investment Act of 2002 (Sec. 1503(a)). The DEIP is subject to Uruguay Round Agreement on Agriculture reduction commitments.

Dairy Forward Pricing Pilot Program: See Forward Price Contract Pilot Program.

Dairy Herd Improvement Association (DHIA): An organization whose program is operated jointly with the USDA and the land grant universities to aid dairy producers in keeping milk production and management records. The program assists dairymen in designing breeding programs and testing milk for fat, protein, and solids. The organization collects and processes data, and establishes other programs that may increase dairy farm profitability.

Dairy Import Licensing Program: See Dairy tariff-rate import quota licensing.

Dairy Indemnity Program (DIP): A federal program, begun in 1964, that repays dairy producers and manufacturers of dairy products who, through no fault of their own, suffer income losses on milk or milk products removed from commercial markets because such milk or milk products suffer contamination from registered pesticides. The program also authorizes payments to dairy producers for losses resulting from the removal of cows or dairy products from the market due to nuclear radiation or fallout, and residues of chemicals or toxic substances that may or may not result from the use of registered pesticides. Authority for the program expired September 30, 1985, and the program was not reauthorized in subsequent farm bills. However, annual appropriations were made available by Congress. The program was reauthorized by the Farm Security and Rural Investment Act of 2002 (Sec. 1503(b)). It was formerly known as the Dairy Indemnity Payment Program (DIPP).

Dairy Management, Inc. (DMI): Established in March 1994, a joint undertaking of the National Dairy Promotion and Research Board and the United Dairy Industry Association. DMI’s purpose is to provide better coordination of producer promotion funds by having a joint plan, joint budget, and joint execution. DMI works with state and regional organizations to ensure the future success of the dairy industry by integrating marketing, promotion, advertising, public relations, nutrition education, and research programs.

Dairy Market Enhancement Act of 2000 (P.L. 106-532): Signed into law November 22, 2000. The Act amends the Agricultural Marketing Act of 1946 and requires the USDA to regularly collect data on sales of dairy products used to establish minimum prices for Class III and Class IV milk under thefederal milk order program. Those products are butter, cheese, nonfat dry milk, and dry whey. The USDA must also collect information from dairy manufacturing plants on the price, quantity, and moisture content of any dairy products sold. In addition, each dairy manufacturer and any other person storing dairy products must report on the quantity of dairy products stored.

Dairy Market Loss Assistance Program (DMLA): The Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 1999, provided direct cash payments to dairy producers facing greatly reduced milk prices. Producers qualified for the payments if their dairy operation marketed milk commercially in the U.S. anytime during the fourth quarter of 1998. Payments were limited to the first 26,000 hundredweight produced in either calendar year 1997 or 1998. The actual payments were calculated by dividing the amount made available ($200 million) by the total eligible hundredweights of milk from all approved dairy operations. Similar programs were authorized in the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 2000, which provided $125 million for 26,000 hundredweight for DMLA-II, and the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 2001, which provided $675 million for 39,000 hundredweight for DMLA-III for supplemental payments to producers who received payments under DMLA-II and to new dairy operations in 2000. The Farm Security and Rural Investment Act of 2002 attempted to replace ad hoc emergency payments with National Dairy Market Loss payments. See Marketing loss (assistance) payments, and Milk Income Loss Contract program (MILC).

Dairy Options Pilot Program (DOPP): To address the problems of increased price volatility and reduced price-supports, the Federal Agriculture Improvement and Reform Act of 1996 (Sec. 191) authorized the establishment of pilot programs for the use of futures and options. Producers in selected counties must have operated a dairy producing at least 100,000 pounds of milk over six consecutive months during the previous twelve months. Under the DOPP, producers could purchase milk put options on a maximum of 600,000 pounds of milk. Through the options contracts, producers were able to buy a kind of price insurance. When milk prices fell below the insured price (or strike price), the put option contract increased in value and paid the producer the difference minus the premium or cost of the option. The DOPP was the first such program established and trained milk producers in the use of put options in a price risk management strategy. The USDA provided 80 percent of the cost of the put option premiums and up to $30 per contract of the brokerage commissions for up to 600,000 pounds of a producer’s future production. The Agricultural Risk Protection Act of 2000 (Sec. 134) expanded the program to up to 300 counties with no more than 25 counties in any state. Authority for the program ended December 31, 2002. See Options pilot program.

Dairy price-support program (DPSP): USDA indirect support of the farm price of milk by the purchase of surplus storable manufactured dairy products, such as nonfat dry milk, cheese, and butter, from dairy processors. Under provisions of the Federal Agriculture Improvement and Reform Act of 1996, the dairy price-support program was scheduled to expire on December 31, 1999. Congress extended the program in 2000 and again with passage of the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 2001, which extended the program until May 31, 2002. The Farm Security and Rural Investment Act of 2002 (Secs. 1501-1502) extended the authorization of the program through December 31, 2007, at the current level of support, allowed the USDA to adjust purchase prices twice a year to minimize government expenditures, and authorized a new counter-cyclical payment program.

Dairy product mandatory reporting: The Dairy Market Enhancement Act of 2000 established a mandatory reporting system for dairy products inventories and prices. It required the National Agricultural Statistics Service to regularly collect data on the prices and inventories of cheese, butter and nonfat dry milk sold by dairy manufacturers. The Farm Security and Rural Investment Act of 2002 (Sec. 1504) amended the Dairy Market Enhancement Act of 2000 to include “substantially identical products” designated by the USDA as part of the mandatory reporting system.

Dairy Production Disaster Assistance Program: An emergency program administered by the Farm Service Agency to help eligible dairy producers who suffered losses (diminished production or milk produced but not marketed) from recent natural disasters. The payments were available to producers in areas that suffered a disaster from November 27, 1997, through May 1, 1998, and that received a Presidential or Secretarial disaster designation. Assistance was only available to producers located in the primary designated counties and not the contiguous counties.

Dairy Production Stabilization Act of 1983 (7 U.S.C. §§ 4501-4514): Title I of the Dairy and Tobacco Adjustment Act of 1983. The Act authorized a national producer program for dairy products promotion, research, and nutrition education to increase human consumption of milk and dairy products and reduce milk surpluses.

Dairy products: See Dairy products (eligible), Manufactured dairy product(s), Manufacturing (grade) milk, and Storable manufactured dairy products.

Dairy products (eligible): Under the Dairy Recourse Loan Program, eligible manufactured dairy products were cheddar cheese, butter, and nonfat dry milk. See Dairy Recourse Loan Program, Manufactured dairy product(s), Manufacturing (grade) milk, and Storable manufactured dairy products.

Dairy Promotion and Research Program: A national producer program for dairy product promotion, research, and nutrition education to increase human consumption of milk and dairy products and reduce milk surpluses. This self-help program is funded by a mandatory 15-cent-per-hundredweight assessment on all milk produced in the contiguous 48 states and marketed commercially by dairy producers. It is administered by the National Dairy Promotion and Research Board. The Dairy Production Stabilization Act of 1983, as amended, provided that dairy producers could direct up to ten cents per hundredweight of the assessment for contributions to qualified regional, state, or local dairy product promotion, research, or nutrition education programs. Under the Farm Security and Rural Investment Act of 2002 (Sec. 1505), an assessment on imported dairy products was authorized to help fund the research and promotion program. See Fluid Milk Promotion Act of 1990.

Dairy Recourse Loan Program: A program to assist dairy processors in managing inventories of eligible dairy products and to assure a greater degree of price stability for the dairy industry. As authorized by the Federal Agriculture Improvement and Reform Act of 1996, the USDA was mandated to establish a recourse loan transition program beginning January 1, 2001. The Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Act, 2001, delayed implementation until January 1, 2002. The Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Act, 2002, repealed authority for the program. No authority for the program was included in the Farm Security and Rural Investment Act of 2002.

Dairy Refund Payment Program (DRPP): Under authority of the Omnibus Budget Reconciliation Act of 1990 and the Omnibus Budget Reconciliation Act of 1993, dairy assessments were refunded to dairy producers for a given calendar year if the producer marketed no more milk than the producer marketed in the preceding year. The program was designed to refund price reductions paid to the Commodity Credit Corporation by dairy producers who later reduced their milk production. The authority for the dairy assessments was repealed by the Federal Agriculture Improvement and Reform Act of 1996 (Sec. 141).

Dairy surplus: See Surplus(es), and Surplus area(s).

Dairy tariff-rate import quota licensing: Import licensing, incorporating the Uruguay Round Agreement that provided for increased access to the U.S. market for dairy articles (primarily cheese), is used by the USDA to administer the tariff rate quota system for imports of dairy products. The tariff rate quotas are applied in two tiers, with the lowest rate being applied for a specified quantity of imports and the higher tier applied to any imports in excess of the specified amount.

Dairy Termination Program: See Milk Production Termination Program.

DALR$: Debt and Loan Restructuring System

Dam: A female parent.

Damaged kernels: Kernels or pieces of kernels that have sprouted or are internally damaged as a result of heat, moisture, insects, weather, mold, or microbes.

Damaging weather and related conditions: Damaging weather includes drought, hail, excessive moisture, freeze, tornado, hurricane, earthquake, or excessive wind, or any combination thereof. Related conditions include insect infestations, plant diseases, aflatoxin, or other deterioration of a crop or commodity that is accelerated or exacerbated naturally as a result of damaging weather occurring prior to or during harvest.

Dark-cutting beef: Believed to be the result of a reduced sugar content of the lean meat at the time of slaughter. The dark color of the lean meat is present in varying degrees, from that which is barely evident to so-called black cutters in which the lean is actually nearly black in color and usually has a “gummy” texture. Although there is little or no evidence that indicates the “dark-cutting” condition has any adverse effect on palatability, it is considered in grading because of its effect on acceptability and value.

Daughter product(s): See Pesticide degradate(s).

Day-haul operation: The assembly of workers at a pick-up point waiting to be hired and employed, including transportation of such workers to agricultural employment and the return of such workers to a drop-off point on the same day.

dbh: Diameter at breast-height

DCP: Direct and Counter-Cyclical Program

DDT: A widely used, colorless, odorless, water-insoluble synthetic pesticide that attacks the nervous system of animals and birds. DDT is a persistent, broad-spectrum pesticide that lingers in the environment and accumulates in the food chain. Because of damage to wildlife and the potential harm to human health, DDT was banned in 1972 in the U.S.

Dead animal disposal: The disposal of dead animals by composting, rendering, incineration, disposal in a permitted landfill, or burial on-site.

Dealer trust: The proposal to provide protection for producers and livestock markets who sell livestock to dealers. The trust would operate in much the same manner as the packer trust and the poultry trust authorized by the Packers and Stockyards Act, 1921, as amended.

Dealer(s): Under provisions of the Packers and Stockyards Act, 1921, any person (not a market agency) engaged in the business of buying or selling livestock in commerce, either on his own account or as the employee or agent of the vendor or purchaser.

Debarment: Discretionary federal disciplinary action whereby persons are excluded from participating in covered activities. See Suspension.

Debeak: A poultry management practice designed to reduce the incidences of cannibalism and other aggressive behavior in poultry raised in close confinement. A special method of hot debeaking has been developed for debeaking broiler chicks as early as one day of age. Rather than severing or cutting the beak, a hot blade is used to burn an area near the tip of the upper beak (egg tooth). The procedure is designed to leave a thin base to the tip of the upper beak. This makes it easier for the chick to eat without having a sensitive, raw beak. The tip of the upper beak gradually drops off without apparent injury to the chick, thus leaving a shortened upper beak and a normal lower mandible. Chicks are usually debeaked at the hatcheryor within the first two weeks after hatching. Also Beak trimming.

Debt and Loan Restructuring System (DALR$): A sophisticated Farm Service Agency computer program using information supplied by borrowers to help determine appropriate loan servicing options.

Debt forgiveness: Reducing or terminating a Farm Service Agency farmer program loan, made or guaranteed, in a manner that results in a loss to the USDA, through (a) debt write-down or writing off of a loan; (b) compormising, adjusting, reducing, or charging off a debt or claim; (c) paying a loss on a guaranteed loan; or (d) discharging a debt as a result of bankruptcy. Under the Farm Security and Rural Investment Act of 2002 (Sec. 5310), debt forgiveness does not include consolidation, rescheduling, reamortization, or deferral.

Debt limit: The maximum amount of federal debt that may legally be outstanding at any time. When the debt limit is reached, the government cannot borrow more money until the Congress has enacted a law to increase the limit.

Debt settlement: The resolution of outstanding delinquent loans by cancellation of the debt, compromise, or total repayment.

Debt write-down: For outstanding delinquent farm loans, the reduction of both interest and principle on the debt to a level that equals the value of the collateral securing the debt (recovery value).

Debt/asset ratio: A measure used to determine the financial soundness of a farming operation. Producers whose debts are equal to 70 percent or more of their assets are considered to be in financial difficulty.

Deciduous: (1) Any plant organ or group of organs that is shed naturally. (2) Perennial plants that are normally leafless for some time during the year.

Declining-balance loan(s): On credit-line operating loans, a loan that allows disbursement of funds until the cumulative disbursements total the face amount of the note. See Credit-line operating loan(s).

Decoupled; decoupling: A term used to describe programs that would separate the linkage between government payments to producers and the quantity of a commodity produced or marketed and the quantity of inputs used in production. Producers would make production decisions based on market prices but receive government payments independent of production and marketing decisions. The Federal Agriculture Improvement and Reform Act of 1996 was intended to be the ultimate decoupling legislation. See Coupled.

Defect(s)(timber): Abrupt bend (crook), fungal rot (conk), decay, split, gradual bend (sweep), or other injury that decreases the amount of usable wood that can be obtained from a log.

Defer(red)(ring)(ral): (1) For the purpose of avoiding a loan default, the postponing until a later time, such as the end of the original loan term, the repayment of delinquent loan installments. Both principal and interest may be deferred, or principal only may be deferred while the interest charges continue to accrue. (2) An impoundment of funds for a specific period of time that may not extend beyond the fiscal year in which it is proposed. Under the Impoundment Control Act of 1974, the President could defer funds for any reason, but had to notify Congress that he was deferring the spending or obligation of funds provided by law for a project or activity. Either House of Congress could disapprove the deferral by legislation. The Supreme Court found one-House Congressional vetoes to be unconstitutional, therefore, Congress took away most of the President’s deferral power through provisions in the Balanced Budget and Emergency Deficit Control Reaffirmation Act of 1987. The new deferral provisions allow presidential impoundment for only three reasons: (a) to provide for special contingencies, (b) to achieve savings through more efficient operations, and (c) when such deferrals are specifically provided for by law. The President can no longer defer funds for policy reasons.

Defer(red)(ring)(ral): For the purpose of avoiding a loan default, the postponing until a later time, such as the end of the original loan term, the repayment of delinquent loan installments. Both principal and interest may be deferred, or principal only may be deferred while the interest charges continue to accrue.

Deferred delivery: Futures trading in distant delivery months.

Deferred months: Futures contracts that have a significant time (more than six months) before expiration. Usually referring to the current crop.

Deferred pricing: A method of pricing whereby a producer sells his commodity now and buys a futures contract to benefit from an expected price increase. Although sometimes called hedging, the producer is actually speculating that he can make more money by selling the cash commodity and buying a futures contract than by storing the commodity and selling it later.

Deferred taxation: A form of differential assessment that permits eligible land to be assessed at its value for agriculture. Deferred taxation is similar to preferential assessment, but landowners must pay some or all of the taxes that were excused if they later convert land to ineligible uses.

Deferred-payment contract: In grain marketing, the delaying of payment until a later date for grain that has been delivered and priced earlier.

Deficiency payment(s): A government income support payment made to producers who participated in the cotton, rice, wheat, or feed grains programs. The payment rate was per pound, bushel, or hundredweight. It was based on the difference between the target priceestablished by law and either the market price or the price-support loan rate, whichever was higher. The total payment was equal to the payment rate multiplied by the eligible acreage planted or considered planted, and then multiplied by theprogram yield established for the particular farm. Deficiency payment authority was replaced with declining production flexibility contract payments in the Federal Agriculture Improvement and Reform Act of 1996, and counter-cyclical paymentsunder the Farm Security and Rural Investment Act of 2002.

Defoliant(s): Substance that causes leaves and other foliage to drop from a plant, usually to facilitate harvest. See Defoliate; defoliation.

Defoliate; defoliation: (1) Removal of the leaves of a plant or entire crop by induced abscission or by mechanical means. Chemically induced defoliation is a standard production practice for cotton harvested with a mechanical spindle picker. Cotton mechanically harvested from a defoliated crop contains less trash and green stain than that harvested from an undefoliated crop. Clean cotton receives a better quality grade and higher price than trashy cotton. (2) Defoliation can result from extreme predation by leaf-eating pests. Water or severe nutrient stress and certain pathogens can also induce defoliation.

Deforestation: Practices and processes that change forest lands to nonforest uses.

Degradable: Capable of being reduced or broken down by bacteria or other decomposers.

Degradate(s): See Pesticide degradate(s).

Degradation: The deterioration of environmental resources.

Dehiscent: Splitting spontaneously when ripe.

Dehorn: The removal of horns from cattle, either chemically or surgically. For cattle in confinement, long horns can cause injury by getting caught in fences, gates, and chutes. Horns may also cause severe injuries to other cattle and personnel.

DEIP: Dairy Export Incentive Program

Delaney Clause: Under the food additive provision in Sec. 409 of the Federal Food, Drug and Cosmetic Act, the forbidding of residues of any potentially carcinogenic pesticide in processed foods at concentration levels above those found in the raw product. No potentially carcinogenic residue is tolerated on processed foods if the pesticide is not used on the raw product. The Food Quality Protection Act of 1996 amends the Federal Food, Drug and Cosmetic Act by establishing that pesticide residues in both raw and processed foods will be regulated based on health-based standards set at safe levels, defined as levels at which there is a reasonable certainty of no harm from exposure.

Delaney Paradox: If a pesticide that causes cancer in man or laboratory animals concentrated in ready-to-eat processed food at a level greater than the tolerance for the raw agricultural commodity, the Delaney Clause prohibited the setting of a tolerance. This had paradoxical effects in terms of food safety, since alternative pesticides could pose higher (noncancer) risks and EPA allowed the same pesticide in other foods based on a determination that the risk was negligible.

Delayed pricing: Grain marketing agreement that allows producers to deliver a commodity on one date and to price it at a later date. Upon delivery, title to the commodity is transferred to the elevator, and a contract must be signed within a specified time after completion of delivery. Producers seeking to take advantage of a possible upward movement in prices, favorable tax treatment, or the immediate availability of storage may find this contract acceptable. The risks include elevator bankruptcy and downward price movement. See Price-later contract.

Delineation: For wetland purposes, a certified wetland determination. Natural Resources Conservation Service is the lead federal agency responsible for wetlands delineation on agricultural land for both swampbuster and Section 404. The U.S. Army Corps of Engineers is the lead agency for nonagricultural lands delineation. See Wetland delineation.

Delinting: The removal of short fibers and fuzz from cottonseed. See Linters.

Deliver(y)(ed)(ies)(ing): (1) In commodity futures trading, the transfer of the cash commodity from the seller of a futures contract to a buyer of a futures contract. Each futures exchange has specific procedures for delivery of a cash commodity. Some futures contractsare cash-settled. (2) The bringing to the point of sale and transference of possession of the actual commodity.

Deliverable grade(s): In commodity futures trading, the standard grades of commodities or instruments listed in the rules of the exchanges that must be met when delivering cash commodities against futures contracts. Grades are often accompanied by a schedule ofdiscounts and premiums allowable for delivery of commodities of lesser or greater quality than the standard called for by the exchange. See Deliver(y)(ed)(ies)(ing).

Deliverable stocks: (1) Stocks of commodities located in an exchange-approved storage, for which receipts may be used in making delivery on futures contracts. (2) In the cotton trade, cotton certified for delivery.

Delivery month(s): In commodity futures trading, the month established for delivery in a futures contract.

Delivery notice: The written notice given by the seller of his intention to make delivery against an open short futures position on a particular date. This notice, made through the clearinghouse, is separate and distinct from the warehouse receipt or other instrument that will be used to transfer title.

Delivery option: A provision of a futures contract that provides the short with flexibility in regard to timing, location, quantity, or quality in the delivery process.

Delivery point(s): In commodity futures trading, the locations and facilities designated by the futures exchange where stocks of a commodity may be delivered in fulfillment of a futures contract, under procedures established by the exchange.

Delivery price: The price fixed by the clearinghouse at which deliveries on futures are invoiced; generally, the price at which the futures contract is settled when deliveries are made.

DELMARVA: The peninsula of land where Delaware (three counties), Maryland (nine counties), and Virginia (two counties) converge. This area, known for poultry production, is situated between the Atlantic Ocean and the Chesapeake Bay, and is also referred to as the “Eastern Shore.”

Delta Regional Authority (DRA): Authorized by the Consolidated Appropriations Act 2001, the DRA is a federal-state partnership serving a 236-county area in the eight-state lower Mississippi River region. It is led by a federal co-chair and the governor of each participating state. The DRA is designed to remedy severe and chronic economic distress by stimulating economic development through working with multi-county local development districts. The DRA helps economically distressed communities leverage other federal and state programs that are focused on basic infrastructure development, transportation improvements, business development, and job training services. The DRA was reauthorized and amended by the Farm Security and Rural Investment Act of 2002 (Sec. 6027).

Delta Regional Authority Act of 2000: Division B, Title V, of the Miscellaneous Appropriations Act, 2001, as incorporated into the Consolidated Appropriations Act 2001. See Delta Regional Authority (DRA).

Demand curve: As an illustration of demand theory, this curve establishes the relationship between the quantity demanded to the market price of a good. On a graph with price on the vertical axis and quantity demanded on the horizontal axis, the demand curve connects all the points showing a price and the quantity demanded at that price by an individual or group at a specified location and period of time. The demand curve is downward sloping because typically as the price of a good decreases, the amount of the good purchased increases. The market demand curve for a good is the horizontal sum of all individual demand curves for that good.

Demonstration plot(s): A production plot established primarily on a research station to allow the validation of observations realized in laboratory research or to show variety characteristics or evidence for the public to observe.

Demurrage: Excess time taken for loading or unloading a vessel, thus causing delay of scheduled departure. Demurrage refers only to situations in which the charter or shipper, rather than the vessel’s operator, is at fault.

Denali Commission: A tribal, federal, state, and local government partnership established in 1998 to provide critical utilities, infrastructure, and economic support to isolated and distressed communities in Alaska. The Commission is to (a) deliver the services of the federal government in the most cost-effective manner possible by reducing administrative and overhead costs; (b) provide job training and other economic development services to distressed communities; and (c) promote rural developmentthrough the provision of power generation, transmission facilities, modern communication systems, water and sewer systems, and other infrastructure needs. See Denali Commission Act of 1998.

Denali Commission Act of 1998: Division C, Title III, of the Omnibus Consolidated and Emergency Supplemental Appropriations Act, 1999, which created the Denali Commission for the purposes of providing economic and infrastructure development to isolated and distressed communities in Alaska.

Denali Commission Act of 1998 (P.L. 105-277) (42 USC § 3121): Signed into law October 21, 1998. Division C, Title III, of the Omnibus Consolidated and Emergency Supplemental Appropriations Act, 1999, created the Denali Commission for the purposes of providing economic and infrastructure development to isolated and distressed communities in Alaska.

Denitrification: The bacterial reduction of nitrate to nitrogen gas (NO2), nitrous oxide (N2O), and nitric oxide (NO). Denitrification occurs under anaerobic conditions and results in loss of available nitrogen from the soil.

Denitrification: The bacterial reduction of nitrate to nitrogen gas (NO2), nitrous oxide (N2O), and nitric oxide (NO). Denitrification occurs under anaerobic conditions and results in loss of available nitrogen from the soil.

Density: (1) The measure of how much mass is contained in a given unit volume. (2) Population per unit area. See Density (cotton), Density (wool), Stocking density, and Stocking rate(s).

Density (cotton): See Compress standard density, and Standard density (SD) (cotton).

Density (wool): The number of hair follicles per square inch of skin.

Dent (corn): Field corn. The seed has a dent on top of the endosperm, a wedge shape, and may be of any color. Dent corn is used to make starches, oils, livestock feed, ethanol fuel, crayons, paints, and paper. Dent corn also is used to make corn-syrup sweeteners for soft drinks and baked goods. See Sweet corn.

Deoxynivalenol (DON): A naturally occurring mycotoxin produced by several species of fusarium. Wet and cool weather from flowering time on to maturity promotes infection, resulting in scab or head blight in barley, wheat, oats, and rye. Wheat infected with scab has a tendency to have lighter-weight kernels, some of which are removed during normal harvesting and cleaning operations. Also Vomitoxin(s).

Department of Agriculture Reorganization Act of 1994 (P.L. 103-354): Designed to improve coordination among the USDA’s broad range of programs and agencies, the Act affected both the national office and the field structure. Major changes included mandating the closure and consolidation of field offices and the promotion of “one-stop shopping;” elevating the food safety activities; focusing the rural development activities in three new agencies; reorganizing the former Agricultural Stabilization and Conservation Service, Rural Electrification Administration, Soil Conservation Service, Farmers Home Administration, Federal Crop Insurance Corporation, and Rural Development Administration into new mission-oriented agencies; combining the Agricultural Research Service and the National Agricultural Library; combining the Extension Service and Cooperative State Research Service; combining functions of the Grain Inspection Service and the Packers and Stockyards Administration into the new Grain Inspection, Packers and Stockyards Administration; and creating a new National Appeals Division.

Depletion allowance: Deduction from taxable income derived from a wasting asset. The Internal Revenue Code permits the calculation of depletion allowances either on the basis of a percentage of the gross income from the property in question or on a per-unit-of-product basis. Depletion differs from depreciation in that the asset subject to depletion cannot be replaced, such as in mining or oil exploration.

Depooling: The pulling by milk handlers of milk out of a milk marketing order pool for pricing purposes.

Depopulation; depop: The removal, rendering, or other disposal of infected animals by scientifically justified procedures through a government program. Typically, depopulation programs provide producer indemnities and the cleaning and disinfecting of infected animal premises.

Depopulation; depopulated; depop: The removal, rendering, or other disposal of infected animals by scientifically justified procedures through a government program. Typically, depopulation programs provide producer indemnities and the cleaning and disinfecting of infected animal premises.

Depositors: (1) One who places or deposits grain or other agricultural commodities in a warehouse for storage and handling and is the owner of an outstanding warehouse receipt. (2) The holder of an outstanding warehouse receipt.

Depreciation: (1) A decrease in value of real property caused by age, use, obsolescence, or physical deterioration. (2) A noncash accounting expense that reflects the allowance deduction in book value of assets such as machinery, buildings, or breeding livestock.

Depredation: The loss of commercially reared agricultural and aquatic animals due to the predatory actions of land animals, birds, snakes, seals, crabs, flatworms, or starfish.

DES Proviso: As part of the 1962 Drug Amendments to the Federal Food, Drug, and Cosmetic Act of 1938, Congress stated that the Delaney Clause shall not bar approval of carcinogenic drugs and feed additives administered to food-producing animals, if upon examination by methods acceptable to the Food and Drug Administration, no residue of the material could be found in the edible tissues of the animals. The Environmental Protection Agency has interpreted this to mean no residue above a level judged by the FDA to be safe.

Desert Land Act: See Desert Land Entry Act.

Desert Land Entry Act: Signed into law March 3, 1877. The Act was passed in recognition of the limited application of the 1862 Homestead Act.

Disaster Assistance Act of 1989 (P.L. 101-82): Signed into law August 14, 1989. The law provided assistance to producers hurt by drought or other natural disasters in 1988 or 1989. To qualify for financial assistance, crop producers must have lost at least 35 percent of production. The requirement was higher for producers without crop insurance, as well as producers of nonprogram crops and those who did not participate in farm programs. Other assistance was similar to that which was provided in the Disaster Assistance Act of 1988.

Disaster Debt Set-Aside program: Under authority of the Consolidated Farm and Rural Development Act (Sec. 331A), when Farm Service Agency borrowers are located in counties designated as disaster counties, or contiguous counties, and are unable to make their scheduled payments on any debt, the FSA is authorized to consider setting aside some payments to allow the operation to continue.

Disaster payments: Specific authority for federal aid provided to feed grain, wheat, rice, and upland cotton producers when either planting was prevented (prevented planting) or crop yields were abnormally low (reduced yield) because of adverse weather and related conditions. Payments can also be made under special legislation enacted after an extensive natural disaster. The Disaster Assistance Act of 1989, for example, provided payments to crop producers who suffered losses in 1989 because of drought, hail, excessive moisture, or related conditions. Specific disaster payment authority provided in the Agricultural Act of 1949 was repealed by the Federal Crop Insurance Reform Act of 1994.

(2) Improving the productivity of agricultural land by removing excess water from the soil by such means as ditches or subsurface drainage pipes. (3) The downward movement of water through the soil. When this occurs rapidly, the soil is referred to as well drained; otherwise the soil is said to be poorly drained. Most plant roots need oxygen as well as water, and soil that remains saturated (poorly drained) deprives roots of necessary oxygen. (4) Soil characteristics that affect natural drainage.

Drainage basin(s): The land area where precipitation runs off into streams, rivers, lakes, and reservoirs. It is a land feature that can be identified by tracing a line along the highest elevations between two areas on a map; often a ridge. Large drainage basins, such as the area that drains into the Mississippi River, contain thousands of smaller drainage basins. See Watershed(s).

DRAP: Disaster Reserve Assistance Program

Drawback: A refund, in whole or in part, of customs duties paid on the importation of goods which are further processed and then re-exported, or re-exported in same condition as imported.

Dress(ed)(ing): (1) The prepared animal carcass after slaughter. (2) See Top dressing.

Dressed weight: The weight of the prepared animal carcass after slaughter. See Carcass weight (dressed), and Double dressed-weight.

Dressed-weight pricing: When cattle are marketed on a dressed-weight basis, price is established based on the actual hot-carcass weight. The buyer starts with a base “choice” carcass price, adjusts it for expected quality and yield grade, weight premiums anddiscounts, byproducts, slaughter costs, and the packer’s profit. The seller generally pays transportation on dressed-cattle sales.

Dressing percentage: (1) The percentage of the live-animal weight that becomes the carcass weight at slaughter. It is determined by dividing the carcass weight by the live weight, then multiplying by one hundred. (2) The yield of the hot carcass (immediately after slaughter) expressed as a percentage of live-cattle weight.

DRG: Dorsal root ganglia

Dried distillers grain: See Distillers’ dried grains (with solubles).

Drift: See Pesticide drift.

Drill(ing): (1) See Grain drill. (2) Sowing seeds in furrows or holes by hand or machine.

Drip irrigation: Trickle irrigation delivered by plastic pipe or tubing with near-zero water pressure. Water drips from openings (emitters) located at regular intervals along the pipe. The pipe/tubing may be porous to allow further water seepage. Less water is used in drip irrigation than with conventional methods.

Driver (dairy): See Price mover.

Drop credit: The value of the hide and offal products credited back to the producer by a packer.

Drought Policy Commission: See National Drought Policy Commission (NDPC).

Drought stress: The limitation on maximum plant performance imposed by severe water limitation.

Drought tolerance: A total expression of a plant’s ability to stay alive, grow, and ultimately produce grain or fiber, with part of its life cycle under water stress.

DRPP: Dairy Refund Payment Program

Dry cargo: Any cargo, packed or unpacked, carried in nonliquid bulk form. See Bulk cargo.

Dry manure management (system): Typically, a poultry or beef manure management system that is characterized by either (a) frequent manure removal (at least weekly) and spreading on fields, or (b) long-term, in-house storage of manure. Dry manure can be handled more easily, occupies less space, and creates fewer odor problems than does liquid manure. Dry manure, if stored, should be placed in production buildings, storage facilities, or otherwise covered to prevent precipitation from coming into direct contact with the manure. Long-term, multiyear storage requires drying the manure to about 30 percent or less moisture level. It should be handled and treated to reduce the loss of nutrients to the atmosphere during storage; reduce pathogens, pests, and odors; and make the material a more stable fertilizer when applied to land.

Dry matter (DM): The part that remains after all the water content has been removed.

Dry milk products: Includes dry whole milk, nonfat dry milk, low-fat dry milk, dry cream, dry whey, dry buttermilk, casein, caseinates, and co-precipitates.

Dry mill(ed)(ing): Processing method that separates elements contained in the corn kernel by mechanical force. See Wet mill(ed)(ing).

Dry peas: Traditionally, edible threshed seeds of the garden-type pea plant and the winter field pea plant. These cool-season, annual crops include whole peas, split peas, and sweet peas.

Dry period: The rest period between lactations when a cow is not lactating.

Dry weight: The weight of animal or plant tissue after it has been dried in an oven at 65 degrees centigrade until a constant weight is achieved. Dry weight represents total inorganic and organic matter in the tissue-tissue with the weight of water removed.

Dry whey: Whey that has had the water removed. The composition of the whey has not been altered.

Dry-matter intake (DMI): A key factor in livestock towards maintaining high production, body condition (conducive to reproductive goals), and general systemic/rumen health. Many factors impact dry-matter intake, including palatability of feed ingredients, water intake,feed digestibility, frequency of feeding, feed processing, level of production, cow comfort, cow genetics, rate of passage, and forage quality.

Dry-matter pricing: Refers to either (a) quoting a price on the basis of the pounds of dry matter in a bushel of grain, or (b) subtracting the weight of water from the total weight of grain to obtain the “transactions weight” to be multiplied by the base price to determine payment.

Dry; dries; drying: The removal of undesired moisture in grain or other commodities during postharvest operations by natural (air and sun) or mechanical means, or a combination of the two, for the purposes of preventing premature germination, formation of molds and diseases, and insect infestation.

Dry; drying up; going dry: In dairy cows, the end of lactation when very limited amounts of milk are produced.

Dryland farming: See Dryland production.

Dryland production: Production that utilizes only natural rainfall as a source of water in the production of the crop. Water stress is universally recognized as the factor most limiting to yield. In most areas, dryland production results in lower yields than irrigatedproduction. Various strategies exist to maximize water availability for dryland production, e.g., diking between rows, deep tillage, and early maturing cultivars. Also referred to as dryland farming.
