The purpose of this project is to establish a link between soil health and biological (respiration, nitrogen, and functional groups [genomic and PCR]), physical (aggregation and compaction), and chemical criteria used in the Cornell soil health assessment. The objective is to develop a prediction model for soil nitrogen supplies based on biological soil health indicators.
An accurate estimate of soil nitrogen would enable growers to reduce mineral fertilizer applications for the same crop yields, which would have a direct impact on input costs and reduce nitrogen leaching into the environment. The tests are being conducted on grain corn because it is a nitrogen-hungry crop and has a strong impact on soil quality.
From 2017 to 2020
Accurate estimates of soil nitrogen supply can be used to reduce mineral fertilizer applications.
