Plan, Execute, and Evaluate: In-Season Nitrogen Application

Being Minnesota weather is as variable as the soils across the state, utilizing the nutrients in the soil is something farmers are tasked with each year. With nitrogen being arguably the most important nutrient when it pertains to corn growth, there is much debate as to when to apply nitrogen and how to optimize the availability of this nutrient during the important stages of growth.
