The Minnesota Department of Agriculture (MDA) has released the proposed Groundwater Protection Rule. The purpose of the rule is to minimize potential fertilizer sources of nitrate pollution to the state’s groundwater and protect our drinking water. This proposed rule reflects a revision of the draft Nitrogen Fertilizer Rule that was released in June 2017. The following content outlines the proposed rule and the changes the MDA made as a result of public feedback.
