The relevance of the topic. Intensive and often irrational use of land in agro-landscapes significantly increases the degree of anthropogenic load on the soil. Within the agro-landscape, there is a decrease in the level of soil fertility and a violation of the ecological sustainability of agrocenoses, in some cases there is an increase in the processes of land degradation. In the process of land management activities, organizational and territorial conditions are created for the rational use of arable land, within which it is necessary to replenish the elements of nutrition (N, P, K) to increase the humus content. One of the effective direct ways to ensure the balance of nutrients and organic matter is to apply organic fertilizers during the implementation of a set of agrotechnical measures. The article notes that by improving the technological processes for processing and applying organic fertilizer (using barley straw as an example) with the indigenous strain Humicola fuscoatra VNIISS 016, an accelerated transformation of organic matter and activation of humification processes are observed, which contribute to an increase in humus content in the soil. Purpose. Analysis of land use and development of proposals for improving technological processes of soil cultivation and application of organic fertilizers in order to increase fertility. Methodology. Monographic method, methods of comparative analysis. Results and conclusions. Based on the reliable positive results of the conducted research, we can recommend the use of an improved technological process of processing and applying such an organic fertilizer as barley straw when selecting methods for increasing the fertility of agricultural lands based on organic fertilizers. The practical significance of the study lies in the fact that the improved technology of straw processing and application for improving the fertility of agricultural lands can be used to increase the resistance of agroecosystems to anthropogenic loads, as well as to promote ecological farming, as it has proven to be effective in improving soil fertility. Scope of application. Practice and economics of agricultural environmental management.
