This presentation will help consultants, growers, and other practitioners in the North Central Region of the U.S. Nitrogen management of corn related to weeds will be discussed. Specifically, three questions will be addressed, “How does nitrogen application rate and critical time of weed removal influence corn grain yield?” “How much nitrogen do weeds remove?” and lastly, “What happens to nitrogen in weeds?” By the end of this presentation, the practitioner should know more about nitrogen uptake of weeds in a corn grain production system and how that nitrogen is eventually released back to the soil after weeds are controlled.
