AbstractSoil as an ecosystem is actively involved in the climate formation process. Therefore, it is important to assess soil quality indicators such as total carbon and CO2 emissions. Soil respiration shows carbon emission from soil into the atmosphere. This is a great indicator illustrating the biological activity of soil. The most effective COj emission can be noticed in the afternoon and may reach 0,201 g COj m'^h''. Soil organic matter is considered to be its indicator of quality, which is one of the most important components of biosphere consistency and stability. Following the conducted study, a significant trend towards the content of total carbon in the layer of the surface (0-10 cm) soil was observed.
