As a result of the soil researches morphological and chemical properties of Northeast Aral Sea region of virgin and antropogenic transformed soils are determed. Key parametres and criteria of an assessment of degradation of soils are developed. Map of soil degradation of Northeast Aral Sea region (scale 1:100 000) is created.

The accumulation of carbonates is hydrogenic and biogenic tetem. The C0₂ content of carbonates is directly proportional to groundwater salinity, evaporation rates , and their content in the soil layers is inversely proportional to the salinity of these horizons.

In article the results of researches are driven on influence of different doses of lead and cadmium on biological activity of rice-marsh soils of Akdalinskiy region of the irrigation.

The paper presents the results of surveys on total and mobile forms of heavy metals in the soils of the head of an ancient delta Bakanass river Ily disbursed under the rice crop. Defined background contents studied metals in the soils studied. Found that among mobile forms of metals in the soils studied the biggest share of lead and nickel. A small proportion of the mobile copper. The maps of the content of mobile forms of heavy metals in soils. Is a cartographic analysis of heavy metals in soils.

Questions of contamination of soils and plants in Almaty by heavy metals (Pb, Cd, Zn). The reasons for the deterioration of environmental conditions in the city and possible ways to address them.

The soils are a little stability to petrochemical and concomitant substance in the oil fields Karaarna and East Kokarna

As a result of research on light and meadow gray soils the Hungry Steppe set different efficiency of phosphorus fertilizers on growth, development and productivity of cotton.

In this paper are given the results of investigation the physical- chemical and agrochemical properties of soils in the Kukart watershed of Jalal-Abad region of Kyrgyzstan, i.e. soil texture, humus, C0₂, pH, exchangeable bases and total forms of nitrogen, phosphorus and potassium of soils.

Conducted simulation experiments showed that the zeolite promotes destructive capacity of the indigenous microflora. In all variants of the model experiment making zeolite gradually increased as the level of catalase and gehydrogenase activity. No significant difference in the values of the level of activity of these enzymesin the soil so as to natural and chemically modified zeolite was not observed. Determination of loss of oil in the soil thus showed that the chemically - modified zeolite has no advantages over the natural analogue.

In this paper are given the results of investigation the biological productivity and nutrient cycling of soils in the Kukart watershed of Jalal-Abad region.

New approaches to soil decoding of remote sensing materials of the Earth by the differentiated synthesizing of images in different frequency bands were firstly published in this article. Considerable attention devotes to the infrared range and the luminance of directional light reflection for the analysis of plains regions soil landscapes where using of digital terrain model for these purposes is not applicable.
