Results of research for status of humus and buffer properties of chernozem soils in southwestern Ukraine are summarized. Geographic and genetic features of humus status of soils on the territory under study are identified. Chernozem soils under study are found to reveal a tendency, in dehumification processes, to retain their parameters being typical for soils of the chernozem-type soil-formation. Features of humus formation processes under impact of natural and man-caused factors were studied as well.

The results of the study of dark chestnut soils of fallow lands, which are under restoration in the steppes of central Kazakhstan. The features of the formation and transformation of soil cover soil deposits wormwood plant development stage. Showing the comparative data of soil deposits in relation to the undisturbed counterparts.

The study of the theoretical foundations of conservation and improvement of soil fertility in minimizing processing systems in order to effectively waterkeeping, reducing the rate of mineralization of humus and improve the culture of farming.

In arable lands of Askeran calcium carbonates mostly prevail over magnesium carbonate. In the composition of exchangeable bases dominates the calcium ion. On the soil lots where the content of exchangeable magnesium is more than 30 % of the base it is recommended to add simple super phosphate to the soil.

In cropland of Armenia the development of the erosion is largely promoted through traditional moldboard plowing in the Republic. Moldboard plowing is applied everywhere, regardless of the relief terrain, soil and climatic conditions, agricultural techniques, predecessors, etc. As a result of an enhanced development of erosion processes lead in some cases to the accelerated degradation of arable land. Preliminary determination showed that the magnitude of annual soil loss from erosion by moldboard processing system in a mountain-steppe zone of the republic is from 1,5 to 24,0 t/ha or more. The last was the root cause of searching for relevant agronomic measures to protect arable land on the slopes and develop soil treatment methods.

The faunal and quantitative composition of soil nematodes of no-till and minimum tillage in the chernozems of northern Kazakhstan are presented in the article. Indices, characterizing nematode fauna, showed that no-till are best treated for a habitat of free-living and parasitic nematodes.

The selected key points were laid soil sections with a description of the morphogenetic properties of soil oil-polluted soil and unspoiled natural landscapes. On the site oil-slime on loamy breed with artificial oil pollution and soils, natural landscapes of the oil-contaminated due to spills were laid field experiments on the subject of the destruction of oil products in natural conditions under the influence of ameliorants. The experiments included agronomic techniques of the processing of ground (loamy breed) and the soil, application of mineral fertilizers (N, P), the use of ameliorants - rice husks and bentonite clay. Were defined the field of humidity and the volumetric mass of soil and soil, humus content, nutrients, water extractor hood on the subject of salinization. The soils are characterized by low moisture content, high density. High humus content in oil-contaminated soils is explained by the organic composition of the oil. Zonal soils, subjected to degradation processes, characterized by a low content of humus, elements of power, saline, sum of salts is >1. Type of salinity sulphate, chloride-sulphate on anionic composition, on the cationic composition of calcium and sodium-calcium.

All green plantings have the shape. The green furniture defines architectural and art shape of the city of Astana. Modern methods take root into gardening of the city with complex improvement of objects, use of fountains, reservoirs and other small forms of architecture that, undoubtedly, improves microclimate, sanitary and hygienic conditions.

There were posed field experiments to amend the system of fertilizers on chestnut soils in the south-eastern and north-eastern exposure. Winter wheat of Bezostaya-1 variety was planted in non-irrigated conditions. It is established that during cultivation of winter wheat in non-irrigated conditions in the chestnut soils of Askeran region, the best option is manure 30 t/ha + N₆₀ kg/ha, which provides 22,7 t/ha of the grain yield. With increasing rates of nitrogen on chestnut soils it is possible to obtain a larger yield of winter wheat, and grain yield under irrigation may reach 4050 kg/ha.

Data of long-term researches on a mineral food of the oil crops cultivated in short crop rotations in the conditions of an irrigated zone of the southeast of Kazakhstan are provided in article. Specific responsiveness of flax, mustard, castor-bean tree, colza on change of a food mode of soils at application of fertilizers is studied. The colza and mustard, carthamus on nitrogen-phosphorus appeared the most sympathetic on change of conditions of a phosphoric and nitrogen-phosphorus food, and soy generally on introduction phosphoric and microfertilizers, well respond on introduction of organic and mineral fertilizers flax olive and a castor-bean tree

The micromorphological characteristic is given to the inundated meadow soil with the buried humus horizonformed on thehighfloodplainterraceof the riverSyr Darya.The main featureof soil formation- the development ofalluvialfloodplainprocesses is established.lt is shown thatthe elements ofbeing aweakly stable to the time factor, the vegetable remains and a humus after burial undergo quantitativeand qualitative changesas a resultof secondary (diagenetichesky) processes.. In the buried horizons lying near a day surface, and developing as open system, signs of modernsoil-forming process.

Technology of vermifiltration enables the treatment of the wastewater quickly and easily with a minimum expenditure of energy, without the use of expensive equipment and at low cost. Water is clean, detoxify, disinfected and can be re-used for technical purposes, especially in agriculture, landscaping and gardening. This will save huge amounts of fresh water. The technology is suitable for both rural and urban areas and can be used decentralized, which will reduce the load on the wastewater treatment plant.

World experience and practice in recent years shows that cultivation of corn without scientifically justified agri technology leads to the depletion of arable land and decrease of yields of this crop. Energy-information land cultivation oragroenergy- information agro-technology, widespread implementation of which-is the requirement of future but present day. Application of nanoagromeliorative methods of seed processing and vegetative plants provides a stable growth of crop yields.
