Abstract:
     Features of this invented process are the addition of a small amount of gleyed curing agent and nitric acid reductase inhibitor into ammonium hydrogencarbonate, and the formation of an eutecticum or mixture. The procedure of production is accomplished by improvement of prior process of production of ammonium hydrogencarbonate. Fertilizer produced by said process can increase utility of nitrogen up to 25-30%, extends manurial effect up to 40-60 days, reduces the quantity of manure application by 20-30%. Before planting base fertilizer is applied only once, and top application is saved. The increase in harvest is over 10%.
