Fact Sheet:

When establishing alfalfa: Per 60 pounds of seed, apply 1/4 ounce of molybdenum (2/3 ounce of sodium molybdate) in just enough water to slightly moisten the seed. (CAUTION: DO NOT EXCEED THE RECOMMENDED AMOUNT OF MOLYBDENUM.)

For maintenance, apply 3 pounds of boron (B) per acre annually. Apply 3 ounces of molybdenum (Mo) (8 ounces of sodium molybdate) in 25 gallons of water per acre every two years. Apply the foliar application of Mo in late winter or in spring before new shoots reach 2 to 3 inches in height. To extend the life of alfalfa stands, apply half of the potash (K2O) in spring and half in late summer.
