2023 Abstract - RICE SESSION - MICRONUTRIENT SOLUTIONS IN RICE: Although essential micronutrients are needed by rice in smaller amounts compared to macronutrients, large problems can arise with limited access to these nutrients. Correcting zinc deficiencies is economically and environmentally inefficient due to delay in crop maturity and the extra irrigation and nitrogen inputs needed. Vital plant functions are dependent and catalyzed by micronutrients, and when these nutrients are limiting, so is plant growth and performance. Seed applied micronutrients and bulk fertilizer impregnation provide many agronomic and operational benefits for both the farmer and retailer.--------------------2023 Abstract - CORN SESSION - MINIMIZING NITROGEN LOSS AND MAXIMIZING CORN YIELD WITH UAN: Nitrogen (N) loss in agricultural systems is inevitable, but with proper knowledge and technology, N loss and environmental detriment can be minimized while maximizing economic return. The potential to lose over 30% of the applied N in urea ammonium nitrate via ammonia volatilization is present if proper application methods and proven urease inhibitors are not utilized. Appreciable N loss potential via leaching is also present if proven nitrification inhibitors are not utilized. Proven technology is available to provide the most economic and environmental value to the farmer and retailer.
