For Coastal Plain Soils Only: If the soil test manganese (Mn) level is low, apply 10 pounds of manganese per acre either as manganese sulfate or manganese oxide as a broadcast application.

Fact Sheet:

Inoculate seed at planting. Apply 1 ounce of molybdenum salt per bushel of seed as a seed treatment.

Apply a soluble source of boron (B) at 1/4 pound boron per acre as a foliar spray at the R2 (full bloom) to R3 (early podding) stage. The boron material may be mixed with a compatible pesticide. Your County Extension Agent can provide additional information about boron and pesticide combinations.
