Similar results have shown up in the Southeast. In Kansas, the addition of sulfur produced higher forage yields at nearly all locations. At a research site in Douglas County, the addition of 20 pounds of sulfur per acre increased forage yields by more than 1,800 pounds per acre. According to Ray Lamond, Extension agronomist with Kansas State University, the actual return from sulfur application varies with hay prices. Donald Messick, an agronomist with The Sulphur Institute in Washington, D.C., notes that farmers should consider the type of sulfur used.
Elemental sulfur can be a good choice if it is going to be applied annually.
