On Monday, March 9th, IFCA hosted a recorded webinar with Dr. John Jones of the University of Illinois to discuss key considerations for spring fertilizer planning in Illinois. Dr. Jones provided an overview of current soil conditions heading into the 2026 growing season and shared recent research on nitrogen rate decisions, phosphorus and potassium soil-test calibration updates, and sulfur management. The presentation highlighted updated MRTN nitrogen guidelines, ongoing research to refine Illinois soil fertility recommendations, and the importance of using soil testing and economic return analyses to guide nutrient management decisions for the 2026 crop.
