Soft Rock Phosphate® - GrowGreen Fertiliser
Not all phosphate is immediately available. A number of different factors impact on the solubility of rock phosphate and its availability to plants – this includes the chemical properties of the rock phosphate itself; as well as soil and management factors. The solubility of rock phosphate increases with decreasing particle size.
