Abstract
In the past several years, sulfur (S) deficiency has been showing up more frequently in Iowa fields. This has been especially true in corn and alfalfa fields of northeast Iowa. This is thought to be partially due to Iowa receiving less S in the rainfall due to more stringent air pollution regulations, less S fertilizer applications, and less widespread use of manure. Sulfur fertilizer applications can offer yield increases when S deficiencies are present. The objective of these trials was to evaluate potential for S deficiency and grain yield response in corn and soybean to S applications.
