b'Nitrogen is an important nutrient for corn which, when applied as a fertilizer, can increase yields. However, too much nitrogen can lead to negative impacts on human health, water quality, plant health, and the environment. This episode, Carrie discusses her work testing nitrogen rate recommendation tools and how we can best balance profitability, plant health, and the environment.
