Nitrogen is a very important nutrient for corn production and agronomists invest a lot of time in determining an appropriate application rate/time, assessing N credits from manure and legumes, and worrying about N losses. All aspects of N management impact profitability and environmental quality. Phosphorus is another agronomically important nutrient, which, in recent years, has become a driving force in nutrient management plans. So much focus is placed on N and P, that at times, other nutrients may not be given adequate attention. The goal of this paper is to highlight two nutrients, which will likely have increasing agronomic importance in Wisconsin cropping systems.
