In Ukraine’s territories, there is a potential for rapid growth in organic agricultural production, not only for the domestic market but also for the global market. However, achieving this requires a shift in plant production technologies and ensuring the production of necessary agricultural machinery to facilitate specific technological operations. Global climate change necessitates alterations in regional crop rotations due to reduced plant productivity, especially during the germination stage, where moisture requirements fluctuate. Conversely, the pursuit of maximum yields has led to intensified use of mineral fertilizers, contributing to ecological degradation and decreased soil fertility. Maintaining the balance of nutrients in the soil can be achieved by regular local application of moisture-retaining organic fertilizers in the range of 10–12 tons per hectare. These fertilizers should be derived from organic raw materials possessing a well-developed colloidal structure capable of gradual moisture accumulation and release. Proposed components for producing these fertilizers include sapropel with natural moisture content sourced from freshwater reservoirs. This study presents laboratory and field research results from experimental plots cultivating potatoes, vegetables and soybean, affirming the effectiveness of the proposed technology. The article also describes the construction of machines for local application of moisture-retaining organic fertilizers. A theoretical study of the interaction of organic fertilizer particles with the working body of such machines is presented, and the dimensions and rotation speed are substantiated.
