Abstract
In the recent past, sulfur (S) deficiency showed up more frequently in Iowa fields. Large yield response occurred in corn and alfalfa fields, especially in northeast Iowa. The increase in S response is thought to be partially due to Iowa receiving less S in rainfall because of more stringent air pollution regulations, less S fertilizer applications, higher crop yields, and less widespread use of manure. Sulfur fertilizer applications can offer yield increases where S deficiencies are present. The objective of these trials was to evaluate potential for S deficiency and yield response in corn and alfalfa to S applications.
