Several grain crop producers in Southern Wisconsin have strived to minimize nitrogen (N) loss and improve profitability by side-dressing the majority of the crop’s N requirement when the corn is 12-20 inches tall. Side-dressing minimizes the threat of N loss by leaching or denitrification, which often occurs when N is applied during the fall or spring. However, current UW recommendations do not provide an adjustment factor for side-dressed N. A group of grain producers participated in an on-farm N-rate study to evaluate optimum side-dress N rates for corn. From the study, questions arose whether the 40 pound N credit for soybeans should actually be increased.
