Abstract
Langbeinite (2MgSO.sub.4,K.sub.2 SO.sub.4) is reacted with diammonium phosphate (NH.sub.4).sub.2 HPO.sub.4 to yield a dry farm field fertilizer of grade 21-12-7+1.22 Mg. The chemical process is also adjusted for a dry farm field 'double cropping' fertilizer. The cost of the basic liquid fertilizer containing Magnesium has been likewise reduced. These fertilizers contain magnesium in the presence of phosphorus. The micronutrients, Zn, Cu, Fe, Mn and B may be added in rates proportional to the deficiency shown by soil tests.
