Relef of economy is characterized by a considerable variety. It especially difficult in those places where coal deposits (sandstones and slates) come to a surface and are not covered with quarternary deposits.
Diluvial deposits pochvoobrazut in the lowered relief elements (on the bases of beams, vypolozhenny lowlands of a slope. Delyuvialny deposits were formed by readjournment by the thawed and rain water flows which are not absorbed to the soil, the friable loamy material demolished from nearby slopes of the territory. Signs of slide-rocks are lamination and some sortirovannost of the mechanical particles composing it: larger settle above on a slope, the smallest at a foot of slopes. In places of a close bedding of ground waters they are salted. Here meadow and meadow and marsh soils are formed.
Sandwort and their elyuviya Kamyshevakh's rivers pochvoobrazut mainly on slopes of the radical river bank Kalmius and partially. Elyuvy of sandstones – a product of aeration of the mountain coal breeds which are deposited on a place of the initial education. Sandstone as the general name for sedimentary breeds, consists of fine grains roundish or angular, cemented in more or less dense weight. They incorporate ferruterous connections.
The minimum of rainfall comes for March, April and September. In May, in the period of a kushcheniye when plants need rainfall, them drops out a little. This circumstance is reflected extremely negatively in development of grain crops because the dropping-out summer rainfall is not able to correct adverse effects of dry spring any more.
In the winter after thaw with the subsequent temperature drop of air lower than 0 quite often on fields the ice crust is formed. The period with steady negative air temperatures comes to an end in the first decade of March. By this time also the end of a winter season belongs.
In some cases, on privodorazdelny slopes, mainly in the lower and their middle part and especially on negative elements of a relief, the mineralized ground waters approach close a surface. Education them is connected with penetration, in the spreading rocks of an atmospheric precipitation by an infiltration to a waterproof layer. The mineralization of ground waters is caused by leaching of the salts containing in breeds that is confirmed by analogousness of structure of water extracts from examples of breeds and composition of salts in ground waters.
Formed on a soil sandstone elyuviya srednesuglinisty and tyazhelosuglinisty, hryashchevata, zashchebnena. Dense breed lies superficially therefore an atmospheric precipitation badly filters deep into that leads to very strong superficial drain and washout of soils. Elyuvy of sandstones trudnopronitsay for plants.
In the territory of collective farm pochvoobrazuyushchy breeds are various. The most widespread pochvoobrazuyushchy breeds are the loess and lessovidny loams which lie on the leveled, sublime sites of watersheds and their slopes. Diluvial deposits are much less widespread a sandwort and their elyuviya.
Date of transition of average daily air temperature through 10 is taken for an early autumn. It is observed for the first time to decade of October then frosts begin and there is quite noticeable temperature drop of air. The end of the vegetative period coincides with date of transition of average daily air temperature through 5 and below. At the end of the second decade of November transition of temperature through 0 is observed. The end of an autumn season is connected with this transition.
The great influence renders humidity of air on growth and development of plants. If humidity of air falls lower than 30, the plant develops not normally. The greatest number of days with low humidity fall on summertime, and with high humidity the greatest number of days is necessary for the winter period. Force and the direction of dry winds which increase evaporation of moisture from the soil has impact on reduction of humidity of air and dry up air. In this district east winds are dominating, is more often than others causing a wind erosion. Dry east winds bring frosts and blizzards, and in the spring and summer of a drought and heat in the winter, causing withering of plants. Speed of a wind of 3-5 m/s is often observed., but winds from 10-15 m/s sometimes blow.
Extent and the steepness of slopes renders on extent of manifestation of a water and wind erosion. The increase in length of a slope causes increase of mass of the water arriving to the lower part of a slope in this connection destructive energy of a stream increases.
