| The study aims to develop a method for producing complex organomineral fertilizer that reduces energy consumption, improves fertilizer quality, and enhances environmental safety. The study utilized lignite and weathered coal, as well as phosphorites from four deposits—Kara-Zhyra, Lenger, Maikove, and Shubarkol (Kazakhstan)—collected in 2024 (24 samples). The samples’ pH, moisture content, and water-holding capacity were measured. A statistically significant difference in humic acid content was observed between the Kara-Zhyra and Maikove deposits (p < 0.05). A correlation was identified between potassium carbonate concentration and the conversion degree of humic acids to humates (Pearson correlation coefficient: 0.75, p = 0.03). An increase in phosphorus bioavailability was recorded with a higher proportion of potassium carbonate (p = 0.02, correlation coefficient: 0.78). The impact of urea (p = 0.04) and vermiculite (p = 0.03) on the conversion of humic acids was established. Additionally, urea (p = 0.05) and vermiculite (p = 0.03) influenced phosphorus bioavailability, with an increase in P₂O₅ availability by 4–5% following dosage optimization. Fertilizers containing coal and vermiculite exhibited a “high impact” on soil, while phosphorite and potassium carbonate demonstrated a “moderate” impact. A relationship was identified between heavy metal content and soil toxicity, as well as the influence of fertilizer type on soil pH. The findings facilitate the optimization of the composition and production technology of organomineral fertilizer to maximize nutrient bioavailability, improve fertilizer characteristics, and minimize environmental impact. The developed fertilizer is recommended for agricultural applications. | ||
