Abstract. The exceptional role of organic substances in improving soil fertility constitutes one of the main research directions of modern agrochemical science. In this regard, the application of organic–mineral complexes that positively affect the productivity and quality of agricultural crops, the determination of optimal fertilizer rates, and the development of new technologies represent an urgent issue of scientific and practical significance. The intensity of biological processes occurring in the soil directly determines fertility indicators. The activity of microorganisms requires sufficient soil moisture, the presence of organic matter, and a favorable soil reaction. Within the framework of the present study, a technology for the preparation of organic–mineral complexes based on local raw material resources was developed, and these complexes were tested under cotton cultivation conditions.
