Purdue Nitrogen Trials

Several nitrogen rate trials on corn were established throughout Indiana in 2006. We are striving to determine the optimum N rate needed for corn production across different soils and regions of Indiana. Tools for refining N rate recommendations, like the pre-sidedress nitrate soil test and chlorophyll meter, are also being reevaluated with these experiments. Crop reflectance using active sensor technology is also being investigated as a potential new tool for in-season on-the-go adjustments to N fertilization rates. Results from these studies will be presented and compared with current recommendations and past research.
