Nutrient Management

In 1989, the Maryland Department of Agriculture and the Cooperative Extension Service developed the Nutrient Management program. The purpose of the program is to reduce nutrient loadings, chiefly nitrogen and phosphorus, that pose a threat to the Chesapeake Bay. The efforts are aimed at educating and helping farmers manage crop nutrients more efficiently.  The Pre-Sidedress Nitrogen Test (PSNT) is a management tool that was developed to help farmers determine if additional nitrogen is needed for their corn crops.  It was designed for the purpose of testing fields that has had a history of receiving organic nutrients or was previously planted in a legume crop.
