Lake Bloomington Pilot:
Reducing Nitrogen Loss and Improving Water Quality
There is growing interest in McLean County in the potential to reduce nitrogen loss, improve water quality and possibly increase operational efficiency through shifting from fall fertilizer application to spring application or split application. This two-year spring fertilizer application pilot was funded by an Illinois Environmental Protection Agency 319 grant. Participating producers did not apply nutrients in the fall and instead relied on custom spring application for the 2017 and 2018 growing seasons. McLean County Soil and Water Conservation District organized summer field days in Arrowsmith to share preliminary results of the pilot. In addition, Trevor Sample (Illinois EPA) provided a helpful overview of the Illinois Nutrient Loss Reduction Strategy (NLRS). Shifting to spring fertilizer application or split application could play an important role in achieving the Illinois NLRS nutrient reduction goals.
