A new approach to obtain prolonged nitrogen fertilizers, based on the “gauging” of industrial instant nitrogen fertilizers (ammonium nitrate and urea) by Sorel cement, is proposed. The resulting alkaline complex N(Mg)-fertilizers help neutralize soil acidity (“Sorel cement” - nMg(OH) 2 • Mg(SO 4 , NO 3 ) • mH 2 O also contain plant nutrients). The main quality criteria for prolonged N(Mg)-fertilizers have been developed. The results of evaluating the agrochemical effectiveness of prolonged N(Mg)-fertilizers (as well as urea-formaldehyde fertilizers - UFF) are presented. In the growing experiments the application of these fertilizers contributed to increase in the yield of wheat and green mass of Sudan grass by 20-30%. In the weather and climatic conditions of Tatarstan, prolonged UFF make it possible to obtain a full second mowing of Sudan grass in the autumn period and N(Mg)-fertilizers contributed to an increase in wheat yield by 15%.
