Abstract
Applying comparative morphological, comparative geographical and comparative genetic research methods were able to identify and compare the features of different types of morphological structure of embriozems, formed in man-made steppe and mountain-forest landscapes and match them accordingly with background leached chernozems and brown taiga soils. This approach allowed us to determine the direction oftrends in soil-forming processes technogenic landscapes.

Abstract
Sawdust and Sugarcane bagasse waste are causing severe environmental problems. Growth and reproductive performance of Eisenia foetida in cow manure (CM), sugarcane bagasse (SB) and sawdust (S) waste and its effects on CO evolution was studied under determined laboratory conditions. The results showed that the biomass gain for Eisenia foetida in CM+SB and CM waste were greater than the CM+S waste. Cocoons produced were in the order: CM+SB > CM+S >CM. After adding worms to CM, CM+SB, CM+S, the highest CO emissions related to the fifteenth day. Statistical analysis showed that vermicompost produced after 90 days in terms of nitrogen, phosphorus, potassium and pH had no significant difference with compost. Our trials showed that vermicomposting as an alternate technology for the recycling of S and SB with CM wastes using by Eisenia foetida.

Abstract
In article considered microorganisms as bioindicators a condition of irrigated gray soils light of the South Kazakhstan area are considered. The quantitative and qualitative structure of microbes is studied. The main physiological groups are established: bacteria, actinomycetes, microscopic fungi and their representatives.

Soil fertility

Abstract
By the main purpose of the given investigations a creation of ecological models of fertility was: 1) brown mountain -wood soils middle-mountains with the predominance of beech-hombeam-oak: 2)mountain-wood soils of low-mountain with the predominance of oak and hombeam .On the basis of the creative ecological models an ecological division into districts with the calculation of soil-ecological conditions of lomountain and middle-mountain of the Major Caucasus south-east slope.

Abstract
In this article has been information about ecological situation of tekchnogen violated grey - brown soils around industrial objects of Sumqait massive of Absheron. The ecological balls along konturs were fined of vasis results balls of bonitet, balls heavy metals and correction coefficients on land constructions and shosse -iran ways, common territories and middle balls.

Soil reclamation

Abstract
The article presents data on the effect of the test plowing rice straw treated with biomeliorant on the humus status of low productive rice-marsh soils. It has been established that the introduction of the studied soil of rice straw treated with biomeliorant leads to stabilization of humus status periodically flooded rice soils, despite the peculiarities of rice cultivation in the specific conditions that create special conditions for mineralization and removal of products of organic matter mineralization with a downward current of check water for almost the growing season rice crop.

In the results of agroecological assessment of soils under suger beet on south-east slopes of Great Caucasus with using soils-climatic formula, was revealed, that grey-brown dark soils are given 97 bals, grey- brown ordinary-79; grey-brown light-52; grey-brown irrigation-69; balls in according

Abstract
In the article discusses granulometrical composition of soils and cause their changes in the soils profile across oilfield of Kokaarna and East Kokarna. It can be caused by more intense clay formatn loss of on-site ooze of surface soil horizon as a result of water and wind erosion bringing fine material from overlying horizons.

Abstract
This study investigated microstructure of gray-brown desert soil, meadow-desert solonetz and clay takyr of the Eastern Aral sea region. Micromorphological studies showed the surface of the gray-brown soils had gray porous crust, poor differentiation of the soil profile on genetic horizons, intensive mineralization of plant residues, which rich in wax-resins, formation of organic-mineral components related to a greater degree with iron compounds than calcium, the ferruginization and argillization degrees of the middle part the soil profile, distribution of carbonates as spots and gypsum's presence. The surface crust, the salinity of the entire soil profile, solonetsization signs: local distribution of movable clay as thin stream along the edges of the aggregates and distribution of clay carbonate kutan on the pore walls and around the mineral grains and the absence of modern layered humus-clay kutan's illuviation, which typical for solonetzes were determined in the meadow-desert solonetzes. The analysis takyr's microstructure allowed to establish particularity of takyr layers, presence of algae fragments and bunches of biogenic origin, poorly developed process of humus accumulation, argillaceous and carbonate content of the entire soil profile.
