Abstract
The present invention relates to an amorphous, vitreous phosphorus-potassium fertilizer obtained by melting raw materials containing phosphorus pentoxide (P2O5), potassium oxide (K20), providers of Si02 and silicates, and providers of MgO and CaO. The fertilizer of the present invention is produced by a process of melting the raw materials, followed by quenching, enabling the formation of a vitreous and amorphous material containing phases of phosphorus and of potassium, which are soluble in a weak acid.
