  Abstract

The objective of this study is to develop a production technology for polymer gel-type moisture-retaining complex fertilizers by neutralizing the FER-PANS MCD polymer reagent, formaldehyde, and inorganic acids along with mineral components using nitric acid or sulfuric acid. The parameters for synthesizing gel-like substances based on the FER-PANS MCD polymer reagent, cross-linking agents, and inorganic and organic acids were investigated. The consumption norms of formalin, citric acid, and inorganic acids required for gel formation were determined by analyzing their correlation with gelation time and swelling parameters. Based on experimental studies, moisture-retaining complex fertilizers were synthesized by incorporating the mineral component MAP in varying ratios into the optimally selected formulations. The key physicochemical characteristics of the synthesized complex fertilizers were examined using IR spectroscopy, SEM analysis, thermal analysis, and swelling capacity assessment. SEM analysis of the obtained moisture-retaining complex fertilizers revealed that the MAP-containing variant comprised essential plant nutrients, including O (52.59%), P (18.11%), Ca (0.04%), K (0.11%), Fe (0.03%), and S (0.03%). Additionally, the swelling capacity of the fertilizer, which indicates its moisture retention ability, was found to range from 26% to 36.5%.
