i4i CO Ia'brogé is related to the gupology of the ammonium septic acid and it can be used in the chemical industry for the production of granulated ammonium septic with improved physicochemical and mechanical properties for agricultural storage and storage, and in the agricultural application, and in the agricultural application, and for agricultural chemicals that are used in the agricultural industry, they can be used in the agricultural industry. . A known method of obtaining granulated AMF septica by introducing into it its decomposition gpauconite with a particle size of 45-100 microns in a quantity of O.b. weight.L. Kedostag of this method is the substrate hygroscopic fertilizer, driving the yoke to the adhesion of the granules during storage. The closest in technical significance and the achieved result. The proposed method is to creep granulated ammonium nitrate by introducing into the fertilizer the aluminum booster ™ nitrate or sulfate additive in the amount of OD - 2, O wt% with success. by dusting granules with 0.2% talc from medium I with a diameter of 10 microns. The disadvantage of the known method is that the obtained granules are unstable to the 1U-2W modification transition, as a result of which the fertilizer loses friability and coagulates during storage. Introduced additives do not improve agrohee lichiekie properties of fertilizer. The aim of the invention is to eliminate caking, increase the strength, stability of the granules / to the modification transition during storage, while simultaneously enriching the product with a water-soluble microelectric suspension. The goal is achieved by the fact that according to the method of producing granulated ammonium nitrate by introducing into the fertilizer an aluminum additive additive that is followed by the granulation of the product and dusting the granules, aluminum hydroxide is used as the aluminum-containing additive, which is added together with the cobalt dehydrated salt, and dusting granules as a dusting agent is used perlite hydrophobized with organosilicon compounds. Moreover, hydra-aluminum oxide is introduced in the amount of 0.510%, and the release of cobapt salt is up to a cobalt content of 0.37-0.75% by weight of the fertilizer, as dehydrated 1

The granules obtained are powdered with 6.5% perlite hydrophobized with organosilicon compounds. Modified ammonium nitrate is subjected to physico-chemical tests. Data on the strength of granules

and caking. ammonium nitrate (AC), depending on the amount of the trace element cobalt (Co) and aluminum hydroxide A (OH), in comparison with 902 sbpi cobapt, is administered anhydrous two-porous cobapt. The introduction of dehydrated cobapt (P), formed by huspical flux (for example, sop) in the melt of ammonium separator, promotes the formation of the hexaamine-kobapt-hporida Co complex (NLb) g C8 (2 Hydroxide anKJMKHto, which is added to the fertilizer, has amphoteric properties. The interaction between aluminum hydroxide and the cobapt compound with the formation of a complex (OH) occurs in ppava. The formation of such complexes helps to increase the strength and thermal stability of the granules, reduces their caking. Balta (chlorins, sulfates, etc.) are completely dissolved in ammonium nitrate, which increases the absorption coefficient of microelements by cultivated plants. Silicone water repellents which are produced by domestic industry in the form of a 30% hydroalcoholic solution — hydrophobic creams are used in the form of organic liquids that are produced in the domestic industry in the form of 30% water-alcohol solutions — hydrophobic creams are used by organic manufacturers in the form of 30% aqueous alcohol solutions.

To ammonium nitrate,. Heated to IIO-IOO C add finely dispersed aluminum hydroxide with a dispersion of 10 ~ 10 microns in an amount of 0.5%. The mixture is thoroughly mixed and, at 180-190 ° C, the dehydrated cobalt (II) salt is introduced in an amount corresponding to its 0.37% Go content. Again, the whole mass is stirred for minutes and poured into a porcelain dish filled with glass tubes of 2.5 mm. After cooling the water, fertilizers are knocked out of the tubes and
