“…The amount of incoming organic material also depends on the use of ecosystems. On a pasture plot, the annual intake of organic matter is lower than in ecosystems without grazing and is about 60% in steppe plant associations and 66% in desert ones (Kulakova 2020).…”

“…In the steppes, the return of shoot herbaceous residues to the soil surface is equal to their E upt and the shoot shrubs them at 37% of their annual E upt (Titlyanova et al 2018). The root input accumulating in the soil per year is 41 and 35% of their E upt for desert and true steppes, respectively (Kulakova, 2020).

AimsIn time to the climate changes occurring in the recent decades, studies on the assessment of the influence of climatic factors on the changing natural ecosystems are becoming particularly relevant. This study assesses the relationship between vegetation response to climate aridization and the effect of these changes on soil properties, which is crucial for understanding the sustainability of steppe among the trend toward further global warming. Methods The study demonstrates the influence of climatic factors on the changes in plant biodiversity and biomass, the dynamics of the total stock and the rate of return of chemical elements to the upper soil horizons with the plant organic matter. The chemical composition of soils of different types of steppe was studied, and the effect of changes in vegetation cover on the variability of these soil parameters was estimated. Results The study revealed that during aridization in the steppe zone, there is a change in plant association, what lead to the biomass and bio-productivity of steppe decrease, and chemical elements associated with salts accumulate in soils (Ca, Mg, Na, S, Sr). The accumulation of Ca, K, Na, S, Cl by arid species leads to further degradation of the soil cover (salinization, forming of cambic horizon) and a decrease in its sustainability.Conclusions The data obtained will contribute to a better understanding of the role of plants in the sustainability of the soil cover of modern steppes, which is necessary to predict the response of landscapes to future climate changes.
