description Purpose: to develop a systematic approach to solving the problem of soil fertility based on a model for managing the flows of organic carbon and nitrogen on reclaimed lands. Materials and methods: the working hypothesis of the study is the assumption of the possibility of creating a system of tools for regulating the flows of organic carbon and nitrogen, working within the framework of the principle of nature-likeness and ensuring comprehensive regulation of soil formation factors and increasing the agroecosystem productivity. Results. The conceptual model for managing organic carbon and nitrogen flows on reclaimed lands was developed. The model includes a quantitative calculation of the organic carbon and nitrogen cycles in agroecosystems, the development of scenario forecasts, the development of a control decision and assessment of its execution consequences, the determination of the basic controller’s parameters, the determination of the composition and options for using the controller’s tools, the organization of process monitoring and the assessment of scenario forecasts for actual data. The controller structure of carbon and nitrogen cycle processes for agroecosystems is detailed by the model. The controller includes tools for influencing small nitrogen and carbon cycles, possible ways to implement the tool in a practical application and technologies through which the impact is carried out, with parameters and restrictions specified for a particular case. The basic controller tools are: the plant physiological activity regulation, the phytomass accumulation regulation, the phytomass turnover regulation, the circulation of animal waste regulation, the C:N ratio regulation, the regulation of soil microbiota activity. Conclusions: a conceptual model for managing the flows of organic carbon and nitrogen including a system of tools for the integrated regulation of soil formation factors and increasing the productivity of agroecosystems has been developed.
