Abstract
It has been another moist spring in Iowa. Some locations, like areas in southeastern Iowa, have experienced excessively wet soils several times this spring. Loss of applied nitrogen (N) is once again an issue. But yellow corn does not always equate to N deficiency; plant response to cold and wet conditions (slowed root activity and growth) also impacts foliage color. When corn is small the impact of cold, wet weather, not lack of N, is probably the cause of discoloration because the amount of N taken up by corn to the V6 stage is small (20 lb N/acre or less).
