Sulfur deficiency in your wheat could be showing up in the spring

WOW……fall harvest tended to linger on forever this year! However, we are thankful for the moisture for the wheat crop and crops for this coming spring. It soon will be time to think about your fertilizer topdressing application and you might think about adding sulfur to the tank. In recent years, sulfur (S) deficiency in wheat has become common in many areas of Kansas, particularly in no-till wheat. The likely reasons for this is a reduction in sulfur additions to the crop from atmospheric deposition (there is less S in the air now) and cooler soil temperatures as a result of no-till which slows S mineralization in the soil according to Dr. Dorivar Ruiz Diaz, K-State Research and Extension Soil Fertility specialist. Some crops in the rotation, such as soybeans, can also take up significant amounts of S, resulting in a S deficiency for the following wheat crop.
