"Source water" is the approved surface and groundwater that supplies a public drinking supply. Source Water Protection Interactive Mapping.
Runoff can remove freshly applied nutrients from the targeted field. In joint partnership, the MDA and the National Weather Service have developed a tool to help farmers and commercial applicators with the timing of manure application. The system uses the most current forecast information to predict the likelihood of runoff in coming days. This interactive map provides real time soil temperatures across the state. In areas of the state where fall nitrogen fertilizer application is appropriate Minnesota's nitrogen fertilizer best management practices recommend that fall application be delayed until soil temperatures are below 50 degrees F. Projects are designed to monitor trends over time, demonstrate and evaluate management practices and provide farmers an opportunity to see how a practice works in their "backyard". On-farm trials allow farmers to compare different practices and evaluate their outcomes.Ī number of On-Farm projects are in place to evaluate agricultural practices under conditions that are typical in an area. The Nutrient Management Initiative is designed to help farmers and crop consultants evaluate management decisions using the farmer's actual field conditions. Resources are available to understand the locations of these areas and the probability of contamination. Managing nutrients is of even greater importance near our drinking water sources. Assistance may be available to those that would like to conduct their own on-farm trial. There are a number of tools to assist with the timing of application and a number of resources to learn new strategies. Improving fertilizer management is an important strategy to both improve nutrient efficiencies and protect water quality.
