The article presents data on changes in volumetric mass resulting from a 4 -year collaborative research institutes 2. The given article results indicate that the density of soil using conservation technologies are not an obstacle for the crop.

Faunistic composition, quantity and distribution of them, in soil on the variants of experiments is different, meet in a few. On a quantity, so on family composition prevailing position is occupied by testacean claws - Oribatei, Collembola meet rarely and singly. Microar-tropodes moisture-loving animals.

This study was carried in order to determine the effects different various organic wastes (tobacco prodction waste, wheat straw, tea waste and hazelnut husk) under greenhause conditions on microbiological characteristics (microbial biomass C, basal soil respiration, dehydrogenase activity, urease activity and arlysulphatase activity) in clay -loam soil and rhizosphere (Zea mays indandata) soil of maize plant. The organic wastes were thoroughly mixed with the soil at a rate equivalent to 50 g kg-¹ on air-dried weight basis. Experimental desing was randomized plot desing with there replications in greenhause. The moisture content in soil was mantained around 60 % of maximum water holding capacity by weighing the pots everday. Changes in the microbiological characteristics were determined in the soil and rhizosphere (Zea mays indendata) samples and root free soil taken in 15, 30, 45, 60, 75 and 90 days after the experiment was conducted. At the end of experiment, all organic waste added soil increased microbiological characteristics of soil in comparison with the control (P<0,01) at all experimental periods. Moreover, microbiological characteristics in rhizosphere soil were higher than in root free soil at all organic waste application (P<0,01). Increased of organic wastes on soil microbiological characteristics had different trend (P<0,01), the most increases in the microbiological characteristics in the soil treated with tea wastes and tobacco production waste with supplying of low initial C/N ratio compared to other organic wastes.

Protracted and systematic application of mineral fertilizers on dark chestnut soil differently operate on biological activity of soil under the late cabbage grown in an intensive vegetable crop rotation

Primitive gray soils are mainly spread in the middle zone of Central parts of Beyuk-Duz plain in Nakhchivan AR. The soils - are loamy, low humus, alkaline and carbonate. Mineralogical composition of silt fraction is represented by hydromica, montmorillonite, chlorite, kaolinite; and non-clay minerals such as fine disperse silica and feldspar.

The article presents the study conducted by the industrial areas of the city Ridder. The date demonstrate that the wood-shrub species: Betula pendula Roth., Pinus silvestris L., Caragana arborescens Lam. have reached the ago of full maturity and formed their own phytosphere at the recultivated site. Betula pendula Roth., Pinus silvestris L. are the most frequently met species at the damp in the conditions of natural overgrowing. Caragana arborescens Lam. is not tolerant to an acid medium fnd does not grow on the dumps. Populus laurifolia Ledeb. Mainly, grows at the margins of the dump, it is also not tolerant to an acid medium, therefore the tree is in a depressed condition and the process of branch drying is observed.

The article presents the results of a study conducted on a dark chestnut soils of Central Kazakhstan on the impact of biologics on the chemical composition and the removal of the battery varieties of potatoes. The studies of the first year revealed that the chemical composition of potato varieties and removal of nutrients from the soil varies within wide limits, and are determined by the combined influence of factors such as the hydrothermal conditions of the year and the type of applied biological preparations.

Stated the need of transition to organic agricultural production, refusal from the use of pesticides, synthetic mineral fertilizers, regulators of growth, GMO; main requirements to quality of the soil; the risks expected the farmer, direct and indirect stimulation of organic producers.
