Title: Ca-N-P SOLUTION FERTILIZER
Abstract:
The invention relates to an acidic stock solution manufactured from urea calcium phosphate nitrate, Ca(H2PO4)(NO3)•CO(NH2)2, which can be used for the manufacture of a solution fertilizer. By using the double salt according to the invention, a considerably high calcium content can be achieved in the stock solution compared with the ratio of phosphor and nitrogen; however, so that the sparingly soluble salts in the solution are not precipitated. The physical properties of the salt used are good and it remains homogeneous in storage.
