Abstract: Langbeinite(2MgSO.sub.4 :K.sub.2 SO.sub.4), Na.sub.2 HPO.sub.4, and NH.sub.4 NO.sub.3 are chemically reacted in that critical order to produce a soluble suspension fertilizer of 11N, 8 P.sub.2 O.sub.5, 3 K.sub.2 O + 1.3 MgO containing 14 inorganic nutrients and two enzymes (after KCl has been added). The reactions show the increase in the number and structural changes of the nutrients, its resemblance to bird guano (in content), the ionization of magnesium ammonium phosphate, the inorganic and organic enzymes and the catalytic activity of magnesium in solution, a buffered solution capable of changing from an acid to a base with dilution by water, the evolution of free ammonia at ordinary temperatures, and the enzymes HPO.sub.4 -- and H.sub.2 PO.sub.4 - which are the phosphorus ions absorbed by the roots of plants.There are two separate and distinct kinds of Mg sulfate in this specification. The inventor knows of no other process, use or composition based on this difference.
