For Phosphorus Also called colloidal phosphate. The best natural source of phosphorus and calcium. It is comprised of the bony structures of prehistoric marine creatures mined in Florida from the best deposit in the country. Not the same as the hard rock phosphate, sold by most nurseries and farm suppliers, which is not nutritionally as readily available. Both an immediately available and a long-term source of phosphorus. Available only in 50 lb bags (FOB Grass Valley). Averages 20% P2O5 (3% immediately available), 20% Ca. Soft Rock phosphate should be applied and worked in prior to planting. Use at 5 lb/100 sq.ft. or 1 ton/acre on phosphate deficient soils, less on fertile soils. Supplies P and Ca for up to 5 years after application, depending on the crop. Trees and perennials, use 1-10 lb per planting hole, depending on plant size.
