Abstract:
     Magnesium oxide derived from caleination of marble in ground to fine powder, than mixed with granulous ammonium phosphate and ammonium bicarbonate, formimg magnesium-ammonium phosplate hydrate which covers the ammonium ficarfouate crgstels and prevents them from afsorbing ambient moisture. Properties and chemical stability of this product is better for agricultural fertilization. This product can again be mixed with potassium chloride to be a more valuable compounded fertilizer. This compounded fertilizer looks dry and loose and does not agglomerate. Its stability in 8 times better than common ammonium bicarbonate.
