To improve soil water regime and moisture supply of plants, moisture-swelling polymeric materials are used in the form of hydrogels, which, upon contact with water, rapidly absorb and retain it for a long time in its volume. However, widespread of such hydrogels used in plant growing is currently limited by its high cost. In this connection, from the economic point of view, the use of composite materials as soil conditioners is of great importance, including inexpensive natural raw materials in its composition while maintaining high rates of moisture sorption and water retention. The task is to improve the mixture to maintain the soil balance of various agricultural crops by changing the quantitative ratio of components, significantly cheaper the composition, improving its quality indicators. The purpose of the scientific article is the mixture for maintaining the soil balance of various agricultural crops, which contains an active product based on a granulated hydrogel and a targeted additive.

Complex research is carried out on the rational use of natural pastures with seasonal use in a specific area. The research was conducted in 2015-2017 on the lands of “Batyr” farm in Korday district of Zhambyl region. The pasture lands of the farm consists of 5 independent sites and are located in 3 geographical areas: foothill-steppe (950 hа), foothill-dry steppe (1370 hа) and foothill-semi-desert (1880 hа). The total area of distant pastures is 4.200 hectares. As a result of conducting of geobotanical researches, the farm territory of peasant farm "Batyr" in Korday district of Zhambyl region was divided into seasons (spring-summer-autumn) of their use, the yield of natural herbage and live weight gain of animals was determined. Results of accounting of productivity of natural herbages on zones, seasons of year are given in article and the gain of livemass of animals for the pasturable period is defined. When determining efficiency of sheep it is revealed that higher additional weight of a liveweight is received in experimental group of animal. The seasonal pasture on average in three years of researches at the end of the pasturable period provided an increase of a live weight of rams on 3.370 kg/head at ewes on 8.020 kg/head and lambs of birth year on 8.640 kg/head is more in comparison with control groups of animals. It should be noted that for the pasturable period the increase of alive mass of animals in experimental group in 2017 is higher than a research in comparison with previous years. In 2017 at a pasture of animals on seasonal sites it was applied intra seasonal pasture turnover at which unproductive driving of animals in search of a forage on the grazing square is practically reduced three times, besides degradation of the pasturable territory is completely excluded. It was found that the use of seasonal use of pastures provides more weight gain studied animals compared to animals that graze in one place with an unsystematic manner of grazing. The implementation of the results created the conditions for the restoration of degraded pastures with an increase in the growth and development of vegetation cover up to 15-18 % and an increase in livestock production through rational grazing up to 12 %.

Main problem: Microbial-plant relationships, including epiphytic microflora, are the subject of attention of many scientists. Numerous works confirm the high interest of researchers and the relevance of studying this topic. Despite many years of research, some questions concerning the characteristics of the epiphytic microflora still remain open. It is already a well-known fact that the epiphytic microflora is directly related to the physiological development of the plant, including yield. This is due to the close interaction of the plant with the microorganisms living on its surface throughout the entire growing season. It is also proved that epiphytic microflora has the ability to change characteristics under the influence of environmental factors (temperature, humidity, soil contamination, sunlight, etc.). In this regard, the study of this topic is one of the important areas of biological and agricultural sciences and is of high importance. It should be noted that a significant role in the development of agriculture in the Republic of Kazakhstan and the Pavlodar region is played by representatives of vegetable crops, including tomatoes and potatoes belonging to the Solanaceae family, which indicates the high importance of the plants selected for the study. The combination of the above arguments determines the need to study the epiphytic microflora of plants and establish the regularities of its influence on the adaptive properties of the studied plants of the Solanaceae family, as well as on their productivity. In turn, the study of epiphytic microflora can also contribute to the search for new ways to increase the yield of plants and their resistance to various diseases. Purpose: The article is devoted to the study of the properties and characteristics of the epiphytic microflora of the surface of various organs of plants of the Solanaceae family (on the example of tomato and potato). The variability of the composition and number of epiphytic microorganisms in seasonal dynamics is shown. Methods: bacterioscopic method, fingerprint method, flushing method, Gram staining method. Results and their significance: The characteristics and properties of representatives of epiphytic microorganisms of aboveground (leaf, fruit, flower) and underground (potato fruit) plant organs were studied. The role of the influence of environmental factors on the variability of epiphytic microflora is determined on the example of plants Lycopersicon esculentum Mill. (common tomato) and Solanum tuberosum L. (tuberous nightshade). The differences in the microflora of different plant organs in different periods of vegetation are shown.

An analysis of the mechanical, chemical and pyrogenic impact of the Baikonur Cosmodrome on the environment showed the presence of man-made impacts of the first stages (FS) used on the ecosystems of the impact zones (IZ). This article presents the concept of a controlled landing of spent launch vehicles with liquid rocket engines (LRE) in the expected zones of damage to the ecosystems of the area while maintaining the energy-optimal launch scenario of the launch vehicle. Purpose of the article - development of effective technologies for reducing the anthropogenic impact during launches of promising rockets from the Baikonur Cosmodrome based on theoretical and experimental studies of innovative technologies: reducing the area of impact of parts from launch vehicles; fire and explosion safety, no danger of rocket launchers; controlled descent of used first stages; To solve the problem, it is proposed to create an additional IASM, which will be included in the environmental management system of the Baikonur Cosmodrome. Possible design solutions are proposed based on the evaporation of untreated liquid waste from the tanks of separated parts, their fire and explosion safety, and the use of the obtained vapor-gas mixtures for controlled unloading of separated parts while moving along the landing trajectory to the optimal area. The authors of the article have developed evaluation criteria that characterize the main environmental indicators of the studied areas: fire hazard, soil cover and impact on vegetation are studied for inclusion in the IASM. There are objective requirements and basic rules for the creation of HIASM, which is an integral part of the environmental management system of the cosmodrome.

Main problem: Bird droppings and animal manure contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Purpose: To study the effectiveness of the use of organomineral fertilizer from poultry waste, obtained using biocatalytic processes on the growth and development of plants. Methods: An application for a Patent for the invention of the Republic of Kazakhstan "Method of obtaining organic fertilizer" has been submitted for the developed technology for obtaining organic-mineral fertilizer. In the soil intended for growing seedlings of tomatoes of the “Pepper-shaped Orange” variety and peppers of the “Bogatyr” variety, the resulting fertilizer was applied in the amount of 1 kg per 1 m2 of soil, which was dug to a depth of 8-10 cm and used to grow seedlings in closed ground and subsequent for planting it in open ground. Soil without fertilization was used as a control. The process of soil preparation for open ground, intended for planting seedlings, was carried out for the experimental field with the introduction and control without fertilization. Experimental and control studies were carried out under equivalent climatic conditions, the scheme and technology of watering plants. In total, 100 bushes of each plant species were used in the experiment. Results and their significance: The use of the obtained organomineral fertilizer allows to increase the yield of vegetable crops (tomatoes, peppers) by 20-25% compared to the control. In addition, in the experimental samples, an increase in the number of fruits on a bush was noted with an increase in their size, a decrease in the growing season and the number of damaged fruits.

In this article, comprehensive studies have been conducted on the effective use of natural pastures in conditions of vertical zonality in the project territory of Batyr Korday district (Zhambyl region). The data presented shows how important it is to comply with the norms and loads of pastures for further preservation of pasture yields and prevention of degradation. Consequently, there is a need to develop effective and scientifically-based systems of pasture turnover and the introduction of measures to restore pasture lands in the Zhambyl region, taking into account the peculiarities of the climate and geo-botanical indicators. Pasture lands make up about seventy percent of the entire territory of the Republic of Kazakhstan. The potential productivity of these lands reaches twenty-five and more million tons of fodder units. Pasture is the main renewable forage plant resource. It should be emphasized that haphazard use has led to the fact that land degradation processes occur on 27.5 million hectares of pastures, feed capacity decreases, biological diversity decreases, erosion processes manifest themselves, etc. All this requires the development of science-based approaches to the exploitation of pasture resources, compliance with the basic elements of rational grazing. The current situation may have a twofold path of development. The first way is the absence of strategic initiatives for the effective use of pastures for small producers will lead to a final reduction in the feed capacity of the pastures used. And the second way is small and large-scale use of the huge forage potential of the restored pastures.

In order to successfully conduct agricultural work and obtain a competitive harvest, it is mandatory to carry out spraying operations of crops that require highly qualified personnel, expensive equipment and suitable weather conditions. The use of tractors for spraying fields is the most common solution available at the moment, has disadvantages: high cost, risk of damage to the crop by "hitting", "hooking" or otherwise; environmental damage; due to exhaust gases, the demolition of the solution increases with increasing speed. Using a device designed specifically for spraying equipment is an ideal solution. The purpose of the article is to develop a working model of an automated sprayer for processing agricultural crops. The methods used are: technical justification of a controlled device for processing agricultural crops. Calculation of functional capabilities, algorithms of operation of the proposed automated device: selection of the type of sprayer, engine, chassis, controller, battery, as well as justification of the possibilities of using alternative energy sources (wind energy, solar energy); development of a 3D model of an automation device for anti-weed processing of agricultural crops, printing of parts, assembly of mechanical and electronic parts. Making a prototype using 3D printing; development of the wiring diagram of electronics, software (firmware of the microcontroller; application that controls the settings), testing of the prototype, assembly of the current model; rationale for the optimal use of Arduino and Raspberry Pi boards in this device in a pair: Raspberry Pi will allow you to control processes on the Arduino and easily interact with the Internet when the Arduino itself will perform simple operations such as interacting with electronics and reading sensor readings. The manufactured operating model showed compliance with the goals, a high degree of controllability, environmental friendliness, reduction of energy consumed, labor resources and can be used to scale this device. The developed model of the automation device for anti-weed treatment of agricultural crops can be used not only in agricultural pollination, but also as a mechanism for studying soil parameters: humidity, mineralogical composition and chemical content in the ground, using electronic sensors, as well as an automated mobile platform for any purpose requiring accurate navigation through the territory.

On the territory of the Northern industrial zone of Pavlodar in the area of the industrial wastewater reservoir «Bylkyldak» in some areas of the earth there is soil contamination with mercury, exceeding the MPC for mercury (2.1 mg/kg) by 500 times. The total mass of mercury dispersed in the surface layer of soils is 2.8 tons. The mass of contaminated soil is approximately 208,000 tons. Pollution of the territory is historical. The purpose of the article is to determine the efficiency of chemical binding (immobilization) of mercury in the soil with the Japanese drug Denite® in real field conditions of the territory of mercury contamination in the Northern industrial zone of Pavlodar using an experimental study; to determine the stability of insoluble mercury compounds formed by the preparation at extreme winter and summer temperatures and seasonal fluctuations in open ground. Soil samples were taken for the study at 11 points in the centers of mercury pollution. Laboratory studies were carried out in an accredited analytical laboratory of the Testing Center of JSC Caustic. Soil samples were treated with Denite®, the preparations obtained were stabilized, and water extracts were prepared. The content of mercury in soils, extracts from them, and plants was determined by the atomic absorption method on a RA-915+ spectrometer equipped with RP-91 and RP-91S attachments. As a result of research, the effectiveness of Denite® in the chemical binding of mercury in the soil has been proven and its optimal dosages have been determined. As a result of the positive tests of the technology of chemical immobilization of mercury, the prospect of a practical solution to the issue of demercurization of mercury-contaminated soil on the territory of the Northern industrial zone appeared.

The development, grovth and productivity of livestock depend primarily on providing it with a variety of nutritious feeds. Daily feeds should consist of microbiologically synthesized protein, as well as a variety of seeds, mineral and vitamin supplements of animal and vegetable origin. Indeed, the maximum disclosure of the genetic potential of livestock largely depends on both the quantity and quality of feed. One of the stages of feed quality assessment is the measurement of their chemical composition. The chemical composition is not always constant and depends on many factors, including the species composition of plants, fertilizer application rates, climatic conditions and storage methods. The least accumulation of moisture in the soil was observed in areas where pasture grasses were regularly treated with wormwood. Pacture productivity was also the lowest in the control plots, where the average phyto-chemical composition over three years showed that the dynamics of protein content was the same in all pastures – the protein content reached a maximum at the beginning of the growing sea son and decreased from spring to autumn, while the lowest content of crude protein during harvesting in summer was in control plants of varieties
