Molybdenum is recommended in Kentucky for legumes (soybeans, alfalfa, clovers and other forage legumes) beginning in 1969. The application should be made as a seed treatment and at the rate of 0.4 to 0.8 (4/10 to 8/10) ounces of molybdenum per acre. Molybdenum is recommended only on soils testing less than pH 6.2.
