The lithologic structure of deposits is presented by alevrita thin-layer, micaceous clays brownish-gray, places yellowish-gray, interstratifying sand. Sand fine-grained, places medium-grained to gravel, with inclusions of the ugletsefirovanny remains of plants. Power of rainfall of abrosimovsky suite is measured in limits. 10 m.
On the surveyed sites the greatest weight is occupied by gray forest soils (74 - 89% of total area). They are optimum for meliorative development and agricultural use. Marsh soils make 5,86% (site N, solodi-10 - 23% of the surveyed area of sites.
Gray forest soils are widespread among soils of meadow type of soil formation and are formed, as a rule, on carbonate, is more rare not carbonate quarternary deposits, is more often than srednesuglinisty and tyazhelosuglinisty particle size distribution in the conditions of washing and periodically washing types of the water mode. The dated soils of this type to the raised relief elements with the level of ground waters of 2,0 - 4,0 m.
Alluvial deposits of the third nadpoymenny terrace / alqsh3/have small distribution in the southern boundary territory of a site. The section of a terrace is presented, generally sandy loams, sand with rare pro-layers of clay material. Sandy loams brownish gray, easy dusty, are often replaced with loams, Sand brownish-gray, fine-grained, clay with inclusions of a vegetable derit. Power of rainfall of a terrace makes. 17 m.
Pochvoobrazuyushchy breeds of solonetzic soils are quarternary deposits of heavy and average particle size distribution, contain water-soluble salts, carbonate. Salinization type soda, extent of salinization the weak.
For deposits of suites existence of the legnitizirovanny vegetable remains is characteristic. As well as in all territory of distribution of deposits of suites on this square rainfall of suites is lithologic not sustained in vulgar distribution and on a section.
Peat soils of marsh type of soil formation are presented by the peaty and humous and gley soil with a power of organogenic horizon of 10 - 30 cm. Peat of low-lying type with extent of decomposition more than 35% and an ash-content less than 30%. From vegetation sedge, a willow bush meet. Peat of brown color, water-saturated, sedge and reed. As a rule, under a peat layer, there is the 10 - 12 cm humic layer. Further from top to bottom there is an ogleenny loam.
Thus, it is necessary for improvement of water and physical and agrochemical properties of meadow solonetzic soils: introduction of a half dose of plaster or a phosphite, bezotvalny processing by plows with narrow racks (6sm) on depth of 35 - 45 cm in combination with introduction of organic and mineral fertilizers.
In a damp state the solonetzic horizon strongly bulks up, becomes viscous and in the spring the soil keeps up to sowing works for 10 - 15 days later. In a dry state the arable layer conjoint, is difficult processed.
Soils of short-term excess moistening (gray forest and light-gray forest opodzolenny and the osolodela demanding agrotechnical receptions for improvement of the water-air mode and additional moistening during the droughty period.
On extent of moistening 2 subtypes solody are allocated: malt meadow and malt the meadow and marsh. The majority of the solody are opened and on whitish coloring of the horizon of A2 involved in an arable layer, spots of the solody are accurately allocated against the gray forest soils surrounding them.
Ground waters it is greatest are widespread in the alluvial and lake and alluvial rainfall of srednechetvertichny and sredneverkhnechetvertichny age composing the high plain and the IV nadpoymenny terrace and in verkhnechetvertichny deposits of the II nadpoymenny terrace. Other deposits of quarternary age have very small distribution and ground waters to them, povidimy, makes one water-bearing horizon with ground waters of the second nadpoymenny terrace.
Soils of continuous excess moistening by surface and ground waters (meadow and marsh soils, bolotna, these soils need a drainage and carrying out agrotechnical actions for improvement of the water-air mode.
