Abstract
Abstract Provided is a freely flowing particulate fertilizer essentially consisting of potassium phosphate of the formula K3H3(PO4)2 and of less than 8 wt % water. The stable and not caking fertilizer is characterized by an XRD signal corresponding to 2-theta of about 70°. An economic process for making the fertilizer is also provided.
