A National Report:  State Legal Approaches to Reducing Water Quality Impacts from the Use of Agricultural Nutrients on Farmland


Nutrients play a critical role in agricultural crop production in the United States, but have also detrimentally impacted water quality.  Attention to the nutrient pollution issue has intensified in the last decade, as has the recognition that nutrients used for agriculture are part of the overall nutrient problem.  How are states responding to the water quality challenges posed by agricultural nutrients?  Our national report attempts to answer this question.

In this webinar, we present results of our 50 state survey of laws, regulations and programs that affect agricultural nutrients at the ground level—on the farm.  Our study sought to identify approaches state governments are taking that relate to minimizing water impacts from the use of nutrients on agricultural lands, including both commercial fertilizers and animal manure.  We also aimed to determine whether there are common themes in the types of approaches taken by the states.  We’ll review the findings published in our national report and provide examples and highlights of state laws, regulations and programs from across the country.
