UMN Extension Nutrient Management Podcast

In this episode of the Nutrient Management Podcast, we’re talking about edge of field N and P reduction strategies. What is an edge of field practice and why are they used? What specific practices do our panelists have experience with, and which have the most potential for use in Minnesota? Are these practices a farmer can pursue alone, or do they require local government to be involved? What assistance is available for farmers who are interested in one of these practices?
