Corn Nitrogen Use Chart

Corn Nitrogen Use Chart - Pioneer scientists are conducting extensive research designed to increase corn yields by improving the nitrogen use efficiency (nue) of hybrids. However, when planted in cool soils, the combination of n and. Depending on what growth stage your corn is in, you can utilize growth and uptake charts to estimate how much of your nitrogen uptake is still yet to occur. It further allows the adjustment of nitrogen from the soil, water,. The chart below offers a look at nitrogen uptake throughout the growing season. To optimize uptake of nitrogen (n) fertilizer eficiency and to minimize the adverse impact of n on the environment, we recommend that n be applied at the right time, in the right form, at the. These changes, keys to the availability of nitrogen (n) for uptake by crops, are illustrated in figure 1. Discussion of their significance to the management of n fertility follows. For grain corn production, using 1.1 pounds of n per bushel of expected yield and then subtracting all of the appropriate credits for nitrogen is recommended. This tool provides the optimum nitrogen rate recommendations for the most profitable corn production in nebraska.
