The purpose of research. Analysis of the advantages and determination of the efficiency of machines for subsoil application of liquid nitrogen fertilizers in resource-saving technologies by evaluating the quality of the DRAGON 6000 applicator. Research methods: theoretical (analysis and synthesis of information resources); experimental field; statistical (mathematical processing of research results) according to generally accepted methods. Results. Experimental studies of the influence of the speed modes of the injector wheel of the DRAGON 6000 applicator for application of liquid nitrogen fertilizers CAS on the quality of the technological process were carried out. It is established that during radical fertilization with liquid fertilizers of corn crops with a row spacing of 70 cm the unit is able to provide a daily yield of 120 hectares in 16-row performance and projected 180 ha - in 24-row, provided proper organization of work and staff training. It is noted that in the conditions of growth of prices for mineral fertilizers and climate change introduction of ecological approaches and resource-saving technology of entering CAS on the basis of the DRAGON 6000 applicator is an urgent task which will allow to compete successfully in the world market. Conclusions. Analytical review of domestic and foreign information resources confirms that the technology of subsoil application of liquid mineral fertilizers, in particular urea-ammonia mixtures (CAS), compared with the application of dry and other liquid fertilizers, is becoming more widespread due to better efficiency, which is a derivative of plant nutrition, rational positioning of fertilizers at the required depth, minimization of evaporation losses, improved drought resistance in the cultivation of crops, and also has significant benefits by reducing losses of active substance, ease of adjustment and management of the work process. Studies have confirmed the possibility of providing the presented design of the machine a constant depth of penetration of needles into the soil with a wide range of humidity and different speeds, as well as the ability to choose rational protection zone for cultivation of corn plants without damage to achieve acceptable efficiency of liquid fertilizers. LLC "ROPA-UKRAINE" presents to the market to consumers the applicator of the Ukrainian production DRAGON 6000 which passed production check on the area of 500 hectares during continuous entering of liquid fertilizers of CAS on vegetative plants of wheat and in the course of interrow (radical) entering of CAS on corn crops. 1100 hectares.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Addition of organic amendments is a commonly used practice to offset potential loss of soil organic matter from agricultural soils. The aim of the present study was to examine how long-term addition of organic matter affects the abundance of different soil biota across trophic levels and the role that the quality of the organic amendments plays. Here we used a 17-year-old fertilization experiment to investigate soil biota responses to four different organic fertilizers, compared with two mineral nitrogen fertilizers and no fertilization, where the organic fertilizers had similar carbon content but varied in their carbon to nitrogen ratios. We collected soil samples and measured a wide range of organisms belonging to different functional groups and trophic levels of the soil food web. Long-term addition of organic and mineral fertilizers had beneficial effects on the abundances of most soil organisms compared with unfertilized soil, but the responses differed between soil biota. The organic fertilizers generally enhanced bacteria and earthworms. Fungi and nematodes responded positively to certain mineral and organic fertilizers, indicating that multiple factors influenced by the fertilization may affect these heterogeneous groups. Springtails and mites were less affected by fertilization than the other groups, as they were present at relatively high abundances even in the unfertilized treatment. However, soil pH had a great influence on springtail abundance. In summary, the specific fertilizer was more important in determining the numerical and compositional responses of soil biota than whether it was mineral or organic. Overall, biennial organic amendments emerge as insufficient, by themselves, to promote soil organisms in the long run, and would need to be added annually or combined with other practices affecting soil quality, such as no or reduced tillage and other crop rotations, to have a beneficial effect.

The article explores the biotechnological potential of growing Torch tomatoes in the territory of Dagestan. The characteristics of the hybrid varieties of tomatoes Torch are given. The comparative characteristic of yield indicators of tomato varieties Torch with other varieties cultivated in the southern part of Russia is presented. Five universal soil fertilizer schemes and their application regimes for growing tomatoes were tested as part of the field experiment. The most optimal ratios of the application of nitrogen, phosphorus and potassium for fertilizing soils and fertilizing plants, as an alternative to natural organic nitrogen fertilizers. It is proved that with the introduction of mineral fertilizers against the background of the aftereffect of manure in the soil, the content of nitrates, mobile phosphorus and exchange potassium increases. The influence of the timing of the use of fertilizers on the accumulation of dry matter and the area of the assimilation surface of tomatoes of the Torch variety during the growing season was studied. The dependence of the yield of commodity fruits of the Torch tomato on the doses and timing of the use of fertilizers was established. The effect of fertilizers on individual biometric indicators of Torch tomato plants on the period of mass ripening of fruits is shown; individual indicators of the quality of the Torch tomato fruit in full ripeness are determined depending on fertilizers. It has been shown that the application of fertilizers ensures the yield of fruits of sown tomatoes of the Torch cultivar at the level of 480-500 centner, and also that the tomato plants of the Torch cultivar form the maximum assimilation surface during the period of mass fruit formation. It is shown that the amount of nitrates in the fruits, regardless of the background of cultivation, does not exceed their maximum permissible concentration; in practice, the high yield of tomatoes Torch cultivar in the climatic conditions of Dagestan has been proved.

Abstract The relevance of the topic of scientific research is associated with the use of new liquid fertilizers and a growth regulator in spring wheat crops to increase the yield and quality of grain in the central zone of the Orenburg region. Ensuring food security today is becoming one of the most urgent tasks set by the government of the Russian Federation for domestic agriculture. To solve this problem, it is necessary, first of all, to increase the yield of agricultural crops, rationally using all the factors affecting it. One of these factors is the timely and sufficient application of mineral fertilizers, the cost of which largely determines the size of the cost of production. The emergence of precision farming is associated, first of all, with the improvement of all types of agricultural machinery and technologies, as well as with the rapid development of computer technology, methods of computer modeling and information technology. The integrating basis of the technology is geographic information systems that allow registering and processing information characterizing the state of soil and crops. This information makes it possible to effectively use one of the most significant resources in crop production - mineral fertilizers.

Statement of the problem. The currently used waste (asphalt granulate) for milling non-rigid pavements differs in its characteristics from hot and cold asphalt concrete mixtures as well as crushed stone. The used fleet of machines for compacting the material layer is characterized by a wide range of roller weights and roller parameters, which affects the compaction effect. Ensuring the quality of compaction depends on the compliance of the technological modes of the mechanized link of machines with the properties of the materials used. It is necessary to develop a technology for the device of layers using asphalt granulate and taking into account its properties, thickness, as well as the parameters of compaction machines. Results. The method of development of technology for the device of road structures in the reconstruction and repairs of highways with the use of asphalt granulate is considered. Based on experimental studies the dependence between the load and the deformation of the layer of material, deformation and compaction factor and the values of the angles of contact of the roller with the surface layer of the compacted material is identified with regard to its granulometric composition and thickness of the stacked layer. The simulation results are presented of the interaction of the roller rink with the sealing material obtained analytical dependence for the calculation of stresses in the contact zone of the roller with the material allowing one to set the parameters of the rollers depending on the properties of asphalt granulate.Conclusions. An analytical dependence is obtained for calculating the stresses in the contact zone of the roller with the asphalt granulate layer, which allows one to assign the parameters of the rollers depending on the properties of the material being laid. The suggested method for developing the technology of layer arrangement using asphalt granulate enables the required quality of compaction taking into account the properties of the material, the thickness of the layer to be laid and the parameters of compacted machines.

The purpose of the research is to investigate the quality of spring-finger harrow surface tillage to provoke the germination of carrion depending on the angle of the fingers. Research methods: theoretical – analysis of information resources and research results of spring harrows; laboratory-field – economic tests of the machine with planning of experiment, fixing of agrotechnical indicators; instrumental measurements; mathematical and statistical – processing of the obtained indicators and expert evaluation. Results. Experimental field studies of the quality of surface tillage with a spring-finger harrow were carried out in order to provoke the emergence of winter rapeseed. It was found that the harrow loosens and mulches the top layer of soil well, creating optimal conditions for the germination of weeds and weed seeds. The importance of the agrotechnical measure of field litter management and prospects for the use of spring-finger harrows in the system of soil-protective agriculture is analytically substantiated. Conclusions. The physical parameters obtained as a result of researches of a spring-finger harrow testify that at speed about 20 km / h with increase of an angle of inclination of spring fingers depth of their course increases in 1,6 times from 7,2 cm to 11,3 cm that corresponds to agricultural requirements to spring harrows (4-12 cm). The quality of soil crushing in terms of agronomically valuable aggregates up to 0-25 mm in size increases with satisfactory to excellent values with increasing angle of inclination of the fingers. The results of experimental studies show that the heavy spring-finger harrow Degelman Strawmaster SM 7000-50, in the presence of freshly cut rapeseed stubble of large size and clumps of chaff, provides satisfactory tillage, promoting the germination of rapeseed seeds and improving phytosanitary conditions for future field operations.

In order to obtain high, qualitative and economically profitable rape yield one needs wholesome and integrated manure, with the aim to ensure the plants' needs for nutritive components and to renovate the soil fertility as well. During 2005 - 2007 there was carried research on the increasing rates of potassic mineral fertilizers K0 - K160 against the background of nitrogen fertilizers N80 and N80+40. Using nitrogen fertilizer 80-120 kg ha-1 the obtained yield increase was remarkable indeed: 0.49-1.09 t ha-1. Increased potassium rate K80 - K160 ensured the yield growth up to 0.17–0.42 t ha-1 The highest oil content 48.22-48.89% was ensured by potassium rate K160. Optimal and economically grounded manure rate is N120P60K80 kg ha-1 with the yield level 2.50 t ha-1 and the oil outcome 1086 kg ha-1. In 2007 and 2008 there was carried research on the rates of stick matter AVENTROL (0.7 and 1.0 l ha-1), and its impact on rapeseed yield and quality. In spring rape sowings the yield increase was 0.49-0.78 t ha-1, but in winter rape sowings –0.72-1.03 t ha-1. The seed humidity, at harvest time, was diminished by 2-6 %. The content of oil in seeds increased by 0.52-1.49 %. The use of the preparation AVENTROL ensured the net income: 57,7 - 161,7 EUR ha-1.
