Obtaining of complex hydrogel fertilizers with moisture-retaining NPK based on local raw materials

Abstract

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.

Obtaining water-saving complex fertilizers based on local raw materials

“…FarPAN creates a strong alkaline environment (pH=14) due to the high content of ammonia. On the basis of FarPAN, studies were conducted on obtaining complex-acting fertilizer hydrogels, and physico-chemical analyzes of raw materials were also performed [6][7][8][9][10]. IK-spectroscopic studies of FarPAN in Figure 1 were determined on a Perkin-Elmer FT-IR Spectrum 3 spectrophotometer at a frequency of 4000±400 cm-1, and the obtained results were checked based on special references [11].…”
