Ph of phosphate
WebThe solubility of phosphate minerals is very dependent upon soil pH. The soil pH for optimum phosphorus availability is 6.5 ; At high or neutral pH, phosphate reacts with calcium to form minerals, such as apatite. Under acidic conditions, phosphorus may react with aluminum and iron to form minerals, such as strengite and varescite.
