The Illinois Council on Best Management Practices (CBMP) and the University of Illinois are coordinating the nitrogen project. CBMP is asking ag retailers and certified crop advisers to collect soil samples based on U of I Extension guidelines.
Knowing the amount of nitrogen that remains in fields will provide valuable information from both economic and environmental standpoints, said Emerson Nafziger, U of I crop sciences professor.
The efforts are being coordinated by Dan Schaefer, CBMP’s nutrient stewardship director, and U of I professors Nafziger and Fabian Fernandez, a soil fertility specialist. The project is tied to the Keep it for Crop (KIC) campaign to minimize environmental impact, optimize nutrient use, and maximize yields.
Emphasis will be put on obtaining samples from cornfields that will be replanted to corn in 2013. Instructions for collecting soil samples are posted online at www.KIC2025.org
CBMP is funding the sample shipping and analyses. Test results will be shared with those who collect samples and U of I specialists. The information will be used to develop nitrogen application strategies for next year.
