Laws of formation of a soil cover and morphologic-genetic properties of North-Eastern Kaspy soils are studied; on the basis of generalisation and updating of existing cartographical and analytical materials, and also field researches, the electronic variant of a soil map of territory North-Eastern Kaspy scale 1:500 000, with application of geoinformation technologies in Maplnfo Professional software and use of materials of space imaging is made.

The effects of crude oil contamination on contents organic carbon are considered. Our observation showed that increasing of crude oil in soils brings as well as to increasing of organic carbon.

Stadying of the soil-ecological station the soil covering of Kenkiyak oil field determined the pollution of oil. The oil pollution and soil salinization were reveals on the Kenkiyak oil field territory. The oil and oil field sewage sg. water are the main substance of pollutation.

In this article were given information about the influence of chromium forms on Aktobe soils.

Results of researching to light of physically-chemical features of dark-chestnut soils during seasons and their pollution by heavy metal on territory of Karachaganak field are given in the article. Explored that all industrial zone is polluted by heavy metals in permissible value and only 5 % from all area of field and sanitary protected zone refer to mild dangerous category of pollution.

The article deals with the materials of the researches held in the industrial regions of the Ridder citi. The contamination of natural fresh waters by heavy metals became an especially urgent problem under intensive anthropogenic activity. Heavy metals get into natural waters either with the waste waters or with rain waters filtering through dumps.

Results of a field experiment on studying of comparative influence of biomicrofertilizer «MARS» are presented brought at crops, on productivity and qualities of grain of a winter wheat of a grade «Almaly», grown up on meadow-sierozem light loam soils of the Southeast of Kazakhstan.

Totals of the study of the saline mode of ground facilities-beneficiary are stated in work. It Is Installed, at present one of the main reasons of secondary salinities soil is a discrepancy parameter collector-drainage to network design, of no small importance is as well as breach rotation of crops in crop rotation.

The article deals roith the analysis of the materials treaing the use of ploughed field in the South-Kazakhstan region. The author compared the data roith the ones of 1990,2001, 2005,2008 years. The tendency of decreasing the ared of ploughed field in the agricultural structure is revealed.

In the result of the conducted researches it was determined that due to the combination of mineral fertilizers with manure on irrigated grey soils in Hunger steppe without damaging soil fertility and productivity of cotton, it is possible to reduced twice the annual rate of mineral nitrogen due to application of 201/ ha of manure. This ensures economic effectiveness.

The researches spent on dark-chestnut carbonate soils сухостепной of zone of Northern Kazakhstan on optimization of food and fertilizer of rape, have allowed to establish optimum levels of maintenance of basic elements of food in soil for rape: 30 ±2 mg/kg of soil P₂0₅and 12-15 mg/kg of soil N-N0₃ and a way of their achievement, using formulas: ДР = (Popt-Pfakt) *10, for phosphorus, ДМ = (NonT-Nfak) *7,5*CFhum, for nitrogen (2); It will allow to exclude a template in application of fertilizers purposefully to operate fertility of soils, providing maximum at this conjuncture efficiency of cultures, providing split-hair accuracy of definition of requirement forfertilizers and an economic return.

The article includes the results of the researches on mineral, organic-mineral and biologized systems of fertilizer application in intensive vegetable and vegetable-grass crop rotations on humus condition and contents of gross forms of nitrogen, phosphorus and potassium in the dark chestnut soil in the pre-mountain zone of South-East Kazakhstan.

The article presents the results of determining the dynamics of microorganisms, and teaching-responding to the mineralization of organic nitrogen in the rice-marsh soils. Established that the amplitude of monifitsiruyuschie microorganisms actively involved in the decomposition of organic matter, and that contribute to creating favorable conditions in the nutrient regime of rice in flooded soil Islands. It was found that the number of azotfixings microorganisms correlates with saline-Stu and soil pH: increasing the latter adversely affects freeliving microorganisms that fix nitrogen.

Data on development of private forest business in Republic of Kazakhstan are resulted. The legislative base for development of the given kind of activity is reflected. It is noticed that this sphere of business has now a poor development.

In the article results by the grow up concentration salts NaCl to salt stability seed the safflower. The proof that seeds grow in the local conditions on extent salt stability exceed seed material take from outside.
