Research Project on Fertilizer Value of Manure Reports Results

The Value of Manure Project, a multi-year research endeavor led by Cornell University, reported results from in-field trials in 2024. This statewide project evaluates nitrogen (N) and yield benefits of various manure sources and application methods to corn silage and corn grain. In addition to being a valuable nutrient source, manure can improve soil health, enhance nutrient cycling, and build soil organic matter. The project reported results of eight field trials in 2024. In seven of them, researchers report that manure additions increased yield to levels not achievable with fertilizer alone. The project is continuing with testing of additional manure types and application methods in various soil types and weather conditions.
