Bill Bauer, Agronomist and Owner of B&M Crop Consulting, Coldwater, Mich., says striping in the leaves of corn may indicate deficiencies of nutrients such as sulfur, magnesium or potassium, or some combination of the three. In this brief video, he shows a sample of corn at the V4 growth stage in a northeast Indiana field that exhibits some type of nutrient deficiency.  Bauer encourages growers to take tissue samples to identify specific problems, as such deficiencies can be confused with other problems including nitrogen loss or herbicide damage. South Dakota State University Extension research indicates yield losses on sandy soils, due to sulfur deficiencies alone, can exceed 20 bushels per acre.
