“…The data are summarized in Figure 1. A similar picture is observed for the slurry density for WDC, that is, the density decreases from 1.336 to 1.289 g/sm 3 and from 1.415 to 1.379 3 . At the above temperatures and standards, the rheological properties (viscosity and density) of the main housing unit from the WDC are as follows: viscosity decreases from 41.85 to 16.08 and from 54.11 to 18.38 sPz (Figure 1.)…”

“…An assessment of the technical and economic factors that characterize the production and use of solid and liquid fertilizers indicates the high efficiency of the use of liquid fertilizers. The cost of production of 1 ton of P2O5 in the form of a fertilizer mixture produced based on ammophos is 138% in relation to liquid complex fertilizers [2][3][4].…”

The possibility of producing liquid fertilizers based on nitric acid processing of washed dried concentrate in the presence of monoethanolamine is shown. On the basis of nitric acid extract and monoethanolamine, liquid complex fertilizers with stimulating activity were obtained, composition: P2O5tot. - 10-11%, CaOtot. - 6-7%, Ntot. 12-13% and K2O-5-6%. They contribute to the acceleration of plant growth by 10- 12 days and an increase in yield by an average of 8-10% compared to the control variant. It can be concluded that they can be recommended as liquid complex fertilizers for drip application.

The article covers the decomposition of tricalcium phosphate with thermal phosphoric acid with a concentration of 20, 30 and 40% P2O5 with the replacement of 10, 20 and 30% P2O5 with sulfuric acid and it has been established that, regardless of the content of ammonium nitrate, magnesium sulfate or their combined presence in phosphoric acid, with an increase in the proportion of sulfuric acid, the content of both total and aqueous forms of SO3 in the acidic pulp increases. The highest results of the decomposition coefficient were obtained when phosphoric acid was evaporated to a content of 32.22-25.77% P2O5 and 5.54-9.76% SO3. The SO3 content of both total and aqueous forms in dried products increases with increasing proportion of sulfuric acid. When the proportion of sulfuric acid increases to 20%, the degree of decomposition increases to 93.45% and to 99.55% when replacing 30% P2O5 with sulfuric acid.

This article presents the results of research on the production of fertilizers using water-saving hydrogel on the basis of local raw materials. The reaction of ParPAN raw materials with inorganic and organic acids and in the presence of formalin has been studied. According to the results of research, a new type of hydrogel was synthesized. The degree of swelling of the hydrogel has been found to be related to the amount of formalin and other additives. The composition of the hydrogel composition with mineral fertilizer was developed, its basic physico-chemical characteristics and swelling kinetics were studied. The use of hydrogels as a means of keeping moisture and feed components in arid and low-water agricultural regions of the Republic of Uzbekistan is recommended.
