Abstract
This article presents the results of the analysis of soils from field experimental studies conducted on irrigated meadow soils of the Buston massif in the Ellikkala district of the Republic of Karakalpakstan. The research was carried out within the framework of the 2025 applied research project entitled “Development of Agrotechnologies for Preventing Soil Degradation Processes under Conditions of Global Climate Change.” The fertilizers applied in the experiment had a positive effect on increasing the content of available nutrients in the soil. The most favorable results were obtained with the application of humic-enriched simple superphosphate fertilizer at rates of 0.5 t ha⁻¹ and 1.0 t/ha as well as with humus-rich organomineral fertilizer produced from cattle manure, phosphorite rock, and plant residues at a rate of 7.5 t/ha.
