Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields north of Golden City for the June 14 crop scouting update.

Corn
Corn was in the 8-12 leaf stage and did not show visual signs of nitrogen deficiency.

According to Peter Scharf, the best time to determine if nitrogen deficiency is present is once the soil is no longer saturated. “If making a rescue nitrogen application on corn 4 foot or less tall, broadcast or in-row urea causes less than an average of 4 bushel loss when using a low dust formula on dry leaves. Agrotain coated urea improved yield response on 1-2 foot-tall corn, but not on 3-4 foot-tall corn; the volatized urea may be captured by the leaves of taller corn, reducing the need for Agrotain. Dribble UAN between rows instead of broadcasting to avoid severe yield loss due to leaf burn. If possible only apply nitrogen in deficient areas to get the most economical benefit,” said Scharf.
