Abstract

In the past several years, sulfur (S) deficiency has been showing up more frequently in Iowa fields than what had been seen in the past. Yield response has especially occurred in corn and alfalfa fields in northeast Iowa. Increase in S response may be partially due to less S in rainfall from more stringent air pollution regulations, less S fertilizer applications, higher crop yields, and less widespread use of manure. S applications can offer yield increases where S deficiencies are present. The objective of these trials was to evaluate grain yield response in corn and soybean to S.
