Agricultural nutrients in the wrong places pose threats to water quality in the United States,  but  the  federal  government  has  little  control  over  the  issue.    States  do  have authority over nonpoint sources such as agricultural nutrient runoff, but what are they doing to address water quality threats?  This paper presents an overview of different approaches  states  are  utilizing  to  reduce  agricultural  nutrient  impacts  on  water.  Approaches fall into seven categories that range from statewide reduction strategies to nutrient  application  restrictions  and  external  partnerships.    Voluntary  incentives remain  a  priority,  but  a  slight  trend  toward  mandatory  requirements  exists.    The current  landscape  is  well-populated  with  a  diversity  of  state  actions,  but  funding, impact monitoring and coordination may prove critical to program and policy success.
