DETERMINATION OF THE PHYSICO-CHEMICAL AND COMMERCIAL PROPERTIES OF A NEW TYPE OF PREPARED GRANULAR NITROGEN-SULFUR FERTILIZERS.

The increasing per capita population and the reduction in the area under agricultural crops in the world are intensifying the problem of food security. Providing the population with high-quality food and clothing is a priority task of agriculture in each country. In this regard, the production of mineral fertilizers, which are widely used in increasing the productivity of all types of agricultural crops, is of particular importance. The main commercial properties of the grains of samples of modified AS with the addition of (NH4)2SO4 and NS-fertilizers obtained on the basis of nitrate, ammonium sulfate and urea, were determined using standard methods: grain strength, stickiness, porosity and diesel oil absorption. From the data presented, it was found that with an increase in the mass fraction of modifiers added to the AS slurry in the studied ratios, the commercial properties of NS-fertilizer grains improve compared to AS.
