Abstract

There are a lot of misunderstandings regarding sulfur (S) nutrition for Kentucky crops. Sulfur is considered a seconda r y pla nt nutrient because, although the crop requirement for S is relatively large, it is usually found in soil at concentrations adequate for plant growth and yield so that no fertilizer S is needed. For many years, soil S was maintained by atmospheric deposition. However, more stringent clean air standards require greater removal of S during burning of fossil fuels. That fact, along with increasing crop yields, has caused many Kentucky grain producers to begin to question if S fertilization will increase yield.
