Background: This article investigates the process of obtaining liquid organo-mineral fertilizer (LOMF) based on poultry manure (PM) and phosphorite sludge (PS) in the presence of potassium hydroxide (KOH). Methods: Experiments were conducted with PM:PS mass ratios ranging from 95:5 to 65:35 and solid-liquid (S:L) ratios from 1:1 to 1:3. Results: The results indicated that a decrease in the proportion of poultry manure in the raw material and an increase in the extractant volume led to a reduction in the concentration of total organic matter, humic acids, and fulvic acids in the liquid phase. The maximum organic matter content in the liquid fertilizer (12.78%) was recorded under the conditions of PM:PS 95:5 and S:L 1:1. Scientifically substantiated optimal parameters were identified, allowing for the production of high-quality liquid fertilizer while enabling the efficient utilization of solid residues.
