Laws of formation of a soil cover and morphologic-genetic properties of Northern 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 Northern Kaspy scale 1:500 000, with application of geoinformation technologies in Maplnfo Professional software and use of materials of space imaging is made.

The article gives the characteristics of northern ordinary virgin and cultivated foothill gray soils. It is set those microbiological processes, which lead to complete mineralization, have the primary value in the resolution of vegetative remains. It is noted the low presence of humus, high porosity, micro-aggregation, carbonation of the whole soil profile, the presence of gypsum in a parent rock. There is a formation of optically oriented gypsum by the inner soil weathering and argillization of primary minerals influenced by the process of soil formation; also it is shown the difference in age of humus. It is identified that in the result of long-time gray soils plowing the sigh of degradation appears in arable layer; there is a lack of humus in the soil, the anthropogenic "lessivage" and the structural changers of pore space are observed.

In article is consernet with results of soil and aveliterative researches of an average pary of the Zarafshansky alluvial cone where the Dzhavbajsky district of the Samarkand area is located. In the territory irrigated alluvial-boggy, alluvial meadow swamp, alluvial meadow, alluvial serozemic meadow, alluvial-proluvial serozemic oasis, alluvial serozemic meadow soils, and also irrigated and new irrigated typical grey soils are extended. All this soils have received the full characteristic and the estimation of their ecological

The methodical problems on the determination of quantitative characteristics of soil erosion loss products from agricultural lands of piedmont zone of Kazakhstan are considered in the article. Quantity indicators of washout soils were defined: by supervision on sewer platforms, by the account of a liquid drain and deposits in closing cross section furrow and a method of measurement ravine.

The article includes the results of the research work on study of regulations of Cadmium income to the rice and wheat plants at the beginning stages of ontogenesis depending on the level of contamination of soils in conditions of rice agricenosis. It has been determined that for the sprouts and the roots of the investigated crops the barrier free type of Cadmium accumulation is typical.

In the article, the results of studying of the seasonal iron dynamics under using of rice cultivation technology by seedling method in the pre-sowing of flooded soils are shown. It was found that at the pre-sowing of flooded soils the low-valency forms of iron was not accumulated in the soils in number causing of negative influence to the root of sprouts.

In article dynamic tendencies of distribution of agricultural grounds of Akmolinsky prirodno-agricultural system from the beginning of development virgin and laylands till now are shown. The basic stages of the agricultural development caused by features of social and economic development of given region are allocated.

Sterility of maternal cells of pollen of inter species Triticum x Aegilops of hybrids of the first generation have been described.

On the basis of results of the long-term researches lead on salted groundin perfection of gradation of an index of mobile phosphorus in почвах under cultures of a rice crop rotation, providing optimization of a mineral feed of plants, economy and occurrence of efficiency of application of phosphoric fertilizers.

The article deals with the problem of crude oil pollution on the oil fields of Atraudist. Spilled oil activities still can affect environment, plants and wildlife in several ways. The direct impacts occur when operations disrupt the habitat of the industry's roads and cutlines create acces for other users who the habitat.

As a result of research there are 40 species from 14 genera of family Cydnidae in Kazakhstan. The 11 species are new for Kazakhstan.
