Description

Most com producers apply fertilizer nitrogen (N) several weeks or months before com plants emerge from the soil. N is applied early to obtain price discounts, to complete some field operations early, to avoid practical problems associated with fertilization after crops have emerged, and to ensure that wet weather in May and June does not make fertilization impossible. These reasons seem valid if it is assumed that the early applications of N do not promote significant losses of N before the crop grows.

Early Season Losses of Nitrogen from Iowa Cornfields

Most com producers apply fertilizer nitrogen (N) several weeks or months before com plants emerge from the soil. N is applied early to obtain price discounts, to complete some field operations early, to avoid practical problems associated with fertilization after crops have emerged, and to ensure that wet weather in May and June does not make fertilization impossible. These reasons seem valid if it is assumed that the early applications of N do not promote significant losses of N before the crop grows.
