South Dakota State University Extension and Premier Crop Systems are recruiting corn farmers to participate in nitrogen fertilizer trials.
Jason Clark, SDSU Extension Soil Fertility Specialist, said this research will help experts improve their recommendations for crop producers. Participants in these on-farm trials will have the opportunity to impact nitrogen recommendations and to better understand nitrogen management on their own farms and other farms throughout the state.
“Research in accurate nitrogen rate recommendations is needed because excessive nitrogen fertilizer applications can reduce fertilizer efficiency, create environmental contamination issues, and reduce grower profits,” Clark said.
Location- and farmer-specific data will remain confidential. The trials will use Enhanced Learning BlocksTM to test variables, including nitrogen application. They are used within the farmer’s fields to test different application rates and their efficacy. Trial sizes are 2 to 5 acres, depending on equipment size and direction of travel.
