2024 Abstract - CORN SESSION - NEW TOOLS FOR NUTRIENT MANAGEMENT IN CORN: Corn has become a staple portion of the crop rotation across the Mid-south and more producers are interested in how to properly manage nutrients to optimize yield and productivity. Researchers and Extension personnel have worked diligently to develop new decision support tools to aid producers in corn nutrient management. These tools cover the gamut from preseason potash rate calculators to in- season tissue tests. Our presentation will cover the tools available to producers to help ensure their yields are not limited due to nutrient availability. 2024 Abstract - RICE SESSION - RICE NITROGEN MANAGEMENT: WHAT IS PROTECTING YOUR N FROM LOSS?: Nitrogen volatilization loss in rice production can be severe, and not all volatilization inhibitors are created equal. Volatilization inhibitors have a competitive mode of action on the urease enzyme active site which means that the amount of active ingredient applied to the fertilizer really makes a huge difference on volatilization inhibition and ultimately yield. Volatilization and rice yield data comparing different urease inhibitors will be shown.
