Abstract (English):
Developed technology Slow dissolving granular alkali nitrogen- magnesium fertilizers by mixing nitrogen fertilizer Sorel cement . It is shown that the main products of the interaction of magnesia binder ( MgO ) solutions of magnesium salts [MgSO 4, Mg(NO 3) 2] are nMg(OH) 2·MgSO 4·mH 2O and nMg(OH) 2·Mg(NO 3) 2·mH 2O variable composition. In pot experiments with some grains (wheat, barley ) and industrial crops ( Sudan grass ) growth of grain and green mass using the proposed fertilizer reaches, respectively, 25 % and 35 %.
