In this article, the main issues of legal regulation of state administration of subsoil use in the Khanty-Mansi Autonomous Okrug – Yugra are considered. The relevance of the article is determined by the fact that the Okrug’s further development depends on the effective state (legal) regulation of subsoil use. The importance of the issue of state regulation of the activities of subsoil use entities is due to the fact that the Russian economy has a pronounced raw material orientation. In this connection, the article analyzes the activities of the Department of Subsoil Use and Natural Resources of the Khanty-Mansi Autonomous Okrug – Yugra, which ensures the existence of an effective mechanism for subsoil use management in the region.

The article deals with the issue of optimizing the parameters of a non-driving rotary agitator to ensure high-quality operation of the unit and determines the rational values of the studied parameters in terms of the power intensity of the process.

The article discusses the issue of the destructibility of soil lumps and lumps depending on the processing speed and the definition of rational values, proposed a method for evaluating the working bodies in terms of the energy intensity of the process.

The article is devoted to the issues, problems and solutions arising in the construction in The far North on permafrost soils, in severe natural conditions and at abnormally low temperatures. The authors note that low temperatures below freezing, fogs, short summer and long winter can be significant barriers to construction in this area.

It is promising to create multifunctional forest machines equipped with a set of multifunctional modules for reforestation, fire fighting, road construction, among which modules can be found using soil-grenades, mulchers and other techniques for laying mineralized strips and actively extinguishing forest fires.

Some directions of research of increasing the efficiency of the functioning of disk working organs of forest tillage machines are shown

The article contains data from studies conducted in 2015–2016 in the North-Еastern part of Kazakhstan. In the experiments the effect of various doses of non-traditional fertilizer together with mineral fertilizer on the yield of sunflower was investigated. Various doses and ratios of mineral fertilizers have been applied, which can affect the yield of sunflower. As a source material, varieties of sunflower of Russian breeding Zarya and a hybrid of Fortimi USA breeding and non-traditional fertilizers – zeolite are taken. In order to determine the effect on the fertility of soils, the agrochemical characteristics of soils in land areas and the content of mobile forms of nutrients were studied. The main agrochemical characteristics and content of mobile forms of nutrients for soil of land plots are investigated in the article.

The article presents the results of studying the influence of various schemes of planting seed tubers of Jerusalem artichoke on the rate of plant growth and development in the soil and climatic conditions of the Republic of Karakalpakstan. Differences in the rate of growth and development of plants are revealed, depending on the varietal features of Jerusalem artichoke and the density of their standing. The most optimal scheme for planting tubers of Jerusalem artichoke is 70x40 cm.

As part of logging operations performed patent search of technical solutions for fighting forest fires discussed the possibility of using for this purpose the method of throwing soil studies of the processes of creating a multifunctional machine for a flexible technologies technologies.

The article describes the results of studies on the influence of different doses of mineral fertilizers on armored mites – oribatid mites. It is found that the increase in population density of oribatid mites is in direct relation to the volume of the crops root system. According to the changes in the numbers of oribatid mites under the influence of different doses of mineral fertilizers and comparing population density of these areas with the controlled ones, it was noted by the authors that mineral fertilizers applied to the agricultural crops, have a positive effect on armored mites – oribatid mites.

This article seeks to assess the stress state of the soil mass and forecasting its changes under load from the constructed buildings and structures. This assessment includes the development of the original program, to calculate the voltage at any point in the soil mass; the creation of a mathematical model to estimate the change in voltage, depending on changes in the parameters of the system "The base-foundation".

In field experiments it was tasked to pick an effective system oto protect of spring rape crops from weeds, allowing to receive stable high productivity from commodity rapeseeds. Evaluation of productivity and suitability for the cultivation of oilseeds on commodity and seeds in the region of the Middle Urals in nine cases of intensification of the use of plant protection products in order to evaluate and use in a production environment. It was found that the studied drugs have unequal impact on the growth and development of plants and yield formation.

This article presents the results of microbiological tests of soils in emergency oil and gas facilities in Yakutia. The author found that in the process of self-healing soil is not sufficiently cleansed of hydrocarbon contamination and are in the environmental stress. The signs of soil degradation are thinning or absence of vegetation, phytotoxicity, changes in physical and chemical properties of the soil: formation of lumpy soil structure, hydrophobicity, salinity, high pH values, lack of available phosphorus, nitrate nitrogen, ammonia nitrogen, phytotoxicity.

As part of logging operations performed patent search of technical solutions for fighting forest fires discussed the possibility of using for this purpose the method of throwing soil studies of the processes of creating a multifunctional machine for a flexible technologies technologies.

Soils of moderately dry subzones suffer from periodic drought, deflation and require actions that can weaken the effect of adverse environmental factors. The most relevant measure to stabilize the process of desertification of a dry steppe is to create and maintain viable shelterbelts. Shelterbelts provide soils with favorable conditions, which change the morphological features of soils profile.

The study of the river was carried out when entering the route and in the comparison of the main argument for transparency, turbidity and the flushing of soil particles into the river.

In article the problem of degradation of lands in Primorsky Krai and possibility of use of geobionts as bioremediant is considered.

The following paper discusses the quiestion of soil toxicity on technogenic zones of Orenburg. The work describes the main characteristics of soil covering of the city, soil biological analysis methods and the results of key zones soil biotesting.
