Synopsis Forage production was increased by sulfur applied up to 40 pounds per acre. The subclover component increased up to 80 pounds of S per acre. Annual grass yields at the high rates of S were decreased by clover competition. Higher rates of S application had a greater carry‐over effect than the 20‐pound raw. Subclover and hardingrass had the greatest increase in uptake of S with increasing rates of applied S, while annual grasses had the least.
