Interpretive Summary:

Technical Abstract: Corn is one of the most demanding crops for N and therefore often requires a high rate of N fertilizer to achieve high productivity. Cost of N fertilizer has risen dramatically during the past decade. Our goal was to develop a biologically based tool to improve N management in high N demanding cereal crops. We hypothesized that a biologically based soil N test will (1) increase N fertilizer recommendations in specific soil conditions with low N-supplying capacity to improve productivity and (2) decrease N fertilizer recommendations in specific soil conditions with high N-supplying capacity to alleviate economic loss and environmental threats. Research in this project will help build an even firmer foundation of knowledge in fundamental (process of soil N mineralization) and applied (improved N fertilizer recommendations from a biological soil testing tool) agricultural science that will be vital for helping to solve the persistent water quality issues throughout the estuary regions of the Eastern Seaboard.
