“…As is known, groundwater has significant influence on the saline soils formation. Therefore, the depth of the groundwater table and the degree of mineralization are among the main factors determining the meliorative state of lands and the entire complex of agro-meliorative measures (Babaev et al, 2015;Dixon et al, 2009).…”

The optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m 3 /ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for forecasting their meliorative regime. This work was conducted with the use of traditional ground-based methods of soil research. As a result of the research, data were obtained that allow assessing the water-salt regime, groundwater levels, their mineralization, as well as changes in the physical and hydrophysical properties of the previously reclaimed meadow solonchaks under natural conditions and under alfalfa in the background of deep, horizontal drainage and developing soil biota control techniques, including improvement of the meliorative state of the soil and indicators of their effective fertility.

It was determined that beginning from 1990s increase happened in temperature and amount of the precipitations significantly reduced. These climate changes affected the quantitative indicators of the Kur water. The ion content of the river water considerably rose in 2018 in comparison with 1952 and 1990s. This rise was more intensive towards the river mouth. In 1952 the ion sum in the Girag Kasaman station was 419,0 mg|l, but in 1990 this figure was 608,3 mg|l, in 2018 it was 620,5 mg|l. But in Banka near the river mouth a quantity of ions was 865,0 mg|l in 1952, 874,7 mg|l in 1990, but it was 888,1 mg|l in 2018. The climate alteration affected mineralogical composition and amount of biogenic elements. A quantity of minerals legally rose while approaching the river mouth. Especially this increase has risen even further for 30 years.Change of the Kur water quality in this direction causes formation of some problems in irrigation use. Tons of harmful salts enter every hectare of land. The undrained and old unrepaired drained soil are salinized and create condition for degradation.

“…It is known that erosion leads to a negative impact on the quality of agricultural soils, changes in chemical and biochemical properties, a decrease in the content of organic substances and basic nutrients, and changes in the total content of organic carbon content of humic acids and C:N ratio, levels decreases enzymatic and microbiological activity (Park et al, 2014;Sarapatka et al, 2018). At the same time, there is a transformation of temporal and spatial dynamics agrophysical properties, first of all, erosion and accumulative processes increase, power of humus accumulative horizon decreases (Gabbasova et al, 2016), soil bulk density and porosity change (Gurbanov, 2010), the soil structure becomes degraded and water resistance become essentially reduced (Travnikova et al, 2010;Babaev et al, 2015) and the hydrological regime become disrupted (Wilson et al, 2020).…”

Agriculture is one of the leading branches of the economy in the Republic of Bashkortostan (Russia). Long-term agricultural use of land with the use of plowing has led to a decrease in the thickness of humus-accumulation horizon of soils, reduction of organic matter and nutrients. There is also a deterioration in water-physical properties, the development of water and wind erosion, and a decrease in productivity. Recently, the use of soil conservation farming systems has started, including the use of No-till system. This study presents the results of assessment of physical properties of agrochernozems under conditions of No-ill use. The physical properties of the soil, such as bulk density, humidity, temperature, structural and aggregate composition, were studied using methods and tools accepted in soil science. It is shown that in the upper soil layer (0-20 cm) there is an accumulation of soil moisture, the values of capillary and total moisture capacity, as well as bulk density are approach to the values of nature soil and are optimal for the growth and development of agricultural crops. Structural and aggregate composition is characterized by excellent aggregate state with their excessively high resistance to damaging effects of water. However, in a single case, the soil density increases to a depth of 45 cm. This fact was caused by the impact of heavy agricultural machinery. The declining of soil density can be achieved by treating it with a special bioorganic agent and growing perennial grasses.
