1. Evaluation of Starter Nitrogen Fertilizer Rates for Grain Sorghum Production in the Southern Great Plains Nitrogen (N) is the most essential nutrient for plant growth and is often the most limiting in crop production. Timely applications of N throughout the growing season are critical to maximizing crop yield. Applying N at planting has proven to be an effective practice, giving plants accessible N early on to increase vegetative growth. Although this is commonly practiced in corn production throughout the Oklahoma and Kansas area, little research has been conducted concerning proper N starter rates... M. Thomas, B.

2. Managing High-pH Soils: Restoring Nutrient Function with Polysulphate and Acidic Phosphate Fertilizers High soil pH often reflects the active consumption of hydrogen ions (H⁺) by carbonates and bicarbonates, which suppresses calcium solubility and reduces the availability of phosphorus, potassium, and key micronutrients. These limitations are driven by soil chemistry rather than true nutrient deficiency, restricting nutrient mobility and root access. This presentation will examine Polysulphate® as a functional calcium and sulfate source that improves system efficiency. In addition, ICL... A. Foster, J. Hagele, T. Donoho, D. Tollefson
