Sulfur deficiency in corn, soybean, alfalfa, and wheat

Sulfur deficiency is occurring more frequently in Indiana and Michigan field crops due to decreased sulfur deposition from the atmosphere, increased crop removal due to higher yields, and adoption of cropping practices that reduce the release of sulfur from soil organic matter. In this publication, Purdue and Michigan State researchers explain why it is wise to consider sulfur deficiency as a cause of crop growth problems where yellowing of the foliage is the primary symptom.
