Oil products are among the most widespread pollutants of objects of environment. Near Maikop in 2008 the large center of black oil pollution was formed. This site became the range for studying of consequences of black oil pollution of soils and water objects under natural conditions. In the real work stages of a recultivation of the soils polluted by fuel oil on a site in Maikop are described. Results of application of a biological preparation Destroil for cleaning of reservoirs are considered. The obtained data allowed to draw a conclusion, that the application of the bacterial preparation Deystroil promoted decomposition of oil products before chemically neutral connections both in the soil, and in water objects
About 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that significant impact on the biological activity has duration of sealing, and the longer the period, the higher the negative impact on the enzymes activity. However, a close relationship between humus state of soil and its enzyme activity kept in a condition of ur-ban pedogenesis. The high activity of investigated enzymes is typical to soil horizons which contain the highest amount of soil organic matter

In the article, we have presented the technical and the technological aspects of the design and the construction of forestry mounted equipment proposed criteria for study and assessment of the drive system of a mounted Gripping-cuts off device for tractors of small pulling classes
In the article, the experimental data of the research of physical and mechanical properties of the modified composite materials for an arrangement of the bases of road clothes in conditions of the North are presented
In the article, it is established that in the market conditions of economic recession of repair production, the traditional technological decisions focused on mass and business lot type, have lost the practical importance. Increase of the efficiency of drawing of wearproof coverings with the electropulse way is based on the use of technological possibilities of the way and the principles of technical self-sufficiency of small repair shops. For that, the combined way of processing, replacing use of the traditional technological equipment, with obtaining quality comparable to the existing technologies has been developed
In the article, we present: the analysis of grain combines, a perfect grain combine with new cutter bar of header and new rotation separator with a gentle principle of threshing, the experiments for definition of the optimal parameters of the new separator
In the article, the questions of modeling of the combined arable unit, in particular, in the process of rejection of soil by a lateral surface of rotational working body of active action are considered. Rational values of the parameters and operating modes of rotational working body of active action are received
