Description

Nitrogen (N) fertilization is essential for profitable corn production. Nitrogen is a major input cost and can contribute to water quality impairment. Because application rate is related to economic net return level and nitrate-N concentration in drainage water, rate selection is important to improve overall N management. Also, required N rates can vary between years, therefore, in-season decision aid tools or tests can be helpful for guidance on application rate.
