The article considered soils-melioraive condition soils of the lover part of Ural river. The action of quality and varies norms of irrigated water to melioration condition, soils fertility are determined.

The study found that one of the main factors limiting soil fertility Akdala array irrigation is content was excessive amounts of soluble toxic salts. To increase the effective fertility suggests a number of technologies.

At cultivation crops to use the basic system plainly the carved processing for 10-12 cm with or without processing, which provides a significant increase in the overall environmental and economy of agriculture in comparison with the system used in the manufacture of ploughing. In the subzone of light chestnut soils Ili Alatau in order to improve their humus status on non-irrigated arable land is recommended to use short rotary grain steam converted into grain crop rotations, by replacing the fields of pure steam on the field with oat-pea mixture, or better with a chickpea.

The article deals with the results of the researches of soil nematodes in Kostanay region in new soil and under wheat with treatment.

This article contains the results of studies on the strains of nodulating bacteria chickpeas and lentils in a chernozems southern of Kostanai region.

In work the main regularities of formation of soils and a soil cover of a seaside part of the peninsula Buzachi are shown. Change of morphogenetic properties of soils depending on soil formation conditions is analyzed. Seasonal dynamics of a zasoleniye of saline soils seaside, caused by influence of climatic factors, including atmospheric moistening, flooding is considered at the sgonno-nagonny phenomena and level of a zaleganiye of ground waters.

Results of long-term researches of a problem of nitrogen in agriculture of Northern Kazakhstan are presented. The maintenance and nitrogen forms in soil, laws of change of a nitric mode of soils are major factors defining efficiency of nitric fertilizers and efficiency of cultures. Essentially new approaches to diagnostics and optimization of the nitric food, guaranteeing high profitability and efficiency of use of fertilizers are stated

The analyses of water sample, taken near the tailing dumps of Zyryanovskiy mine fields gross pollution by heavy metals. These sources of water are dangerous to all living organisms. The average coefficient of water migration of copper is 0,014 - 0,58; as for zinc - 0,007-1,08; and for lead - 0,004 0,79; and for chrome - 0,034-0,44. The element blooms out stronger as the coefficient is higher, and water migration is going more intensive.

According to the description of cuts, laid in the natural areas overgrown spoil deposit "Zhanatas" revealed initial signs of soil formation. At the site where the natural overgrowth jf plants has the character of individual process of soil formation is almost absent or very weakly expressed. The profile of all the cuts visible differentiation of dwarf horizons The assessment of soil-ecological functions under technogenesis conditions at the phosphorite deposits opencast development is given in the article. Waste industrial dumps and initial processes of soil formation have been determined in technogenic eluvium of different rock composition.

The article presents the study on the migration of heavy metals in the soils of technogenic zones of Vanadzor chemicals plant. Heavy metals migration depends on the rate of soil pollution, agrichemical indexes and chemical properties of elements. Within the strongly polluted soils the migration of bulk and movable forms of HM is observed at 25-30 cm to 30-45 cm and from 35-40 to 40-50 cm, respectively.

The article contains the precise analytical data of landscapes located on gray soils. According to these data have been mapped terrain slope of 1:100 000 scale map landscapes located in the gray soils in the foothills of the Trans-Ili Alatau, genetic and morphological description of the soil, the overall composition of humus and texture and relative changes of carbonates. Has been created a map of the terrain and slope and also given the degree of erosion. Soil profiles were collected from areas on the 8° slopes and watershed plains, have been refined and defined genetic and morphological changes, soil samples were taken from 10 cm to the material of the breed. For these samples were calculated overall composition of humus, carbonate and texture. It was also determined that the soil erosion is more intense in comparison with plowing virgin soil.
