In order to ensure the food security of our country, after more than 60 years since the experience of plowing virgin lands, the state decided to return to circulation lands that were abandoned for some reason and have not been used in agriculture in recent years. The uplift of deposits will contribute to the overall increase in acreage and partial removal of the "fatigue" of actively exploited arable lands by the introduction of innovative farming systems. When introducing fallow territories into agricultural circulation, it is necessary to take into account agroecological indicators of the soil, moisture saturation of the soil horizon, which directly affects land reclamation measures and land productivity, and it is also necessary to assess greenhouse gas emissions in order to control emissions that are provided for by the Climate Agenda. The work was carried out within the framework of the NCMU "Agrotechnologies of the Future" in the areas of "Research and development of new self-learning intelligent DSS for agroecological optimization of adaptive farming systems" and "Development and implementation of IoT systems for operational monitoring of effective fertility and ecological functions of soils".

In recent years, the main problem of greening urban areas is the development of large areas, which creates an increased load on the soil and leads to a change in the water regime of the territories, thereby potentially increasing the dynamics of greenhouse gases from the soil. To regulate this process, it is necessary to conduct environmental monitoring of greenhouse gas from soils in order to analyze the patterns of their dynamics in urban areas where waterlogging of the soil is often observed. In addition, it is necessary to plant species in such areas that can withstand prolonged moisture without losing their decorative appearance and ecological functions. For scientific research experiments, it is important to create ecological station that will allow testing for environmental research. The materials of the conducted studies can be used to refine the estimates of soil greenhouse gas in conditions characteristic of urban areas with changes in the hydrological regime of the soil.
