Abstract
This article examines the influence of oxidative methods of poultry manure processing on the formation of humus-like substances and the agronomic efficiency of organic fertilizers. Poultry manure in its initial form was treated with ozone and the O₃+H₂O₂ system. The study showed acceleration of polymerization and aromatization processes, an increase in total humus-like substances (HLS) up to 53,7%, and changes in the ratios of humic and fulvic acids. Elemental analysis revealed a decrease in C and H, an increase in O and N, reflecting structural stabilization. Vegetation experiments on cotton (variety “Sultan”) confirmed increased growth and yield, with the maximum effect observed at a 100 kg/ha application rate, demonstrating the high environmental value of the technology.
