Calcium phosphate derived from volcanic ash

VolcanoPhos gives a good calcium, phosphorus, and manganese response on most soils, including high pH soils. High phosphorus availability promotes plant energy and early maturity. VolcanoPhos is particularly helpful for reproductive / fruiting crops because of its high phosphorus and manganese content, which both stimulate fruit set. Apply up to 200 lbs. per acre in low phosphorus soils.
