The article considers the results of numerical studies on the improvement of existing tillage tools, namely, the improvement of the technical parameters of the furrower, which will improve the water-physical properties of irrigated lands in southern Russia with increasing climate change. Every year, the areas of irrigated land are reduced as they are exposed to natural (for example, rains; floods; surface runoff; diversity of soil cover, the influence of micro- and macrorelief) and anthropogenic (for example, non-compliance with irrigation norms, crop rotation composition, soil cultivation rules; introducing incorrect doses of fertilizers; exclusion of technological operations in order to save resources) factors. In this regard, the solution to the problem of preserving the agro-resource potential of the lands is relevant, and its solution guarantees the food security of Russia. Numerical modeling of dangerous loadings of the technical parameters of the slotter-furrower has been carried out, the types and types of equipment have been selected, their parameters have been calculated, as well as the organization and technology of tillage processes.
