Demonstrating Adaptive Nutrient Management Based Nitrogen Management Practices Using Strip Trials, Aerial Imagery, Objective Tests and Guided Stalk Sampling

This project is will demonstrate two important components in adaptive nutrient management process: evaluation of nitrogen (N) use efficiency under various N management practices, and extension education for continuous improvement of N management practices for corn. Demonstrate and quantify the optimal combinations of nutrient source, application rate, placement, and application timing (4 Rs), as measured by impact on nutrient use efficiency and yield for one or more of the following: corn, vegetables, and hay/pasture. Demonstrations are encouraged that show how these optimal combinations change for one or more of the following comparisons: irrigated vs. non-irrigated management, tillage vs. reduced tillage systems, manure-amended vs. non manure-amended systems, and/or organic vs. conventional production systems.
