Description
Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer

Description
The article considers the mathematical task of calculating the transient flow of water in the regulation of concentrated releases of water discharges on stream flows in lower tails of spillway waterworks. An algorithm, analytical solutions based on hydraulic calculations of the process of propagation and transformation of long waves described by Saint-Venant equations are constituted. These equations are nonlinear and have no exact solutions. To obtain approximate solutions these equations are linearized. The efficiency of spillways depends on how accurately hydraulic processes characteristics are measured. Control and direct measurement of characteristics of hydraulic processes in natural conditions is difficult, which requires applying methods of mathematical modeling and simulation studies of transient processes, which are based on the algorithms of functioning of transient hydraulic processes control. Introduction of the developed method for hydraulic calculation of discharge releases to streams, diverting the water from water discharge structures, allows optimize idle and non-technological discharges of water from reservoirs. Considering the highly dynamic nature of the water flow in the lower tails of the dams at concentrated releases of water discharges from reservoirs, development of new methods of hydraulic calculation of extreme discharges and water depths at the critical sections of watercourses with transient regime of water flow is an important task

Description
In this article, we present the results of the experiments on the potential of productivity and accumulation of the root mass of the Alfalfa and Brome-grass, on the content of the main nourishment elements and the consolidation of gross energy in the roots and agroenergetical effect of the collected gross energy in the conditions of permafrost turf soil of the Middle Lena valley. The maximum productivity potential of beans and cereals grass mixture was reached on the basis of the organic mineral nourishment regime: the collected exchange energy – 21,3 GJ, feed units – 1568 and collected raw proteins – 428 kg per ha. Thus, the content of digestible protein in beans and cereals grass mixture agrophytocenoenosis was increased from 118 to 124 g, that exceeded a zootechnic norm (105 g). In general the nitrogen contained in the total root mass of beans and cereals grass mixture agrophytocenoenosis was up to 26,6 centner per hectare and movable phosphorus- up to 33,6 kg per hectare that can serve as the source of nourishment for sown herbs. The maximal stock of gross energy in roots was got in beans and cereals grass mixture agrophytocenoenosis at organic-mineral degrees (humus of 40 centner per hectare once in 4 years + of N120PK60 annually) up to 157,1 GJ/ha, while the accumulation of the root mass reached 140,3 centner per hectare at average annual rates of accumulation of dry substance up to 24,5 centner per hectare. The processes of formation, decomposition and death of roots in the beans and cereals grass mixture agrophytocenosis take place almost in a balance state. Wherein the biological factor, as the inclusion of the Yakut yellow variety of the Alfalfa in the grass stand, plays a positive role

Description
In the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones

INFLUENCE OF ENRICHMENT SEEDS WITH COPPER ON RICE YIELD
06.00.00 Agricultural sciences
Description
We have studied the effect of presowing enrichment with copper on the seed yield of rice. We have found optimum concentration of water solution of copper, which provides higher yields of seeds and evaluated the impact of the enrichment with copper on the growth processes in the plants of rice. The studies were conducted in elite seed-growing enterprise "Krasnoe" of All-Russian Research Institute of rice. It was found that for rice-growing farms of the Kuban region with the aim of increasing the quantity and quality of grain yield it is necessary to make sowing of rice seeds enriched with copper. This application should be carried out by wetting the rice seeds with 0,5 % water solution of the microelement with a semi-dry method, i.e. the rate of 10 liter working solution of copper in 1 ton of seed. The article proves the economic feasibility of enrichment of rice seeds with copper

PROCESSING METHODS OF THE INTENSIFICATION OF EXTRACTION OF NUTRIENTS FROM FRUITS OF WILD PLANTS
06.00.00 Agricultural sciences
Description
The nutrient structure of fruits of the Mountain ash of ordinary Sorbus aucuparia L., sloe of Prunus spinosa and their extracts is investigated. Inside them, the standard methods in biochemistry have determined the content of extractive substances, sugars, titrable acids, vitamins C and P, phenolic and pectinaceous substances. Results of analyses demonstrate that the fruits of wild plants ripening in the conditions of Dagestan – mountain ashes and sloe - can be effectively used as raw materials for receiving extracts which are rich in vitamins, carbohydrates and phenolic connections. The possibility of production of highquality nutrient-rich extracts from these fruits with application of various technological modes and ways of extraction is revealed: duration of insisting of raw materials; various concentration of ethanol in an extractant and ratios raw materials/ extractant. Results of researches demonstrate that at a ratio of raw materials/extractant 1:3 and the 70% content of ethanol in the extractant have come the greatest extraction from vitamin fruits P (routine) and phenols which made respectively 56,0-65,7% and 51,4-68,3%. Increase in extraction of titrable acids and vitamin C is noted at 50% concentration of ethanol in the extractant. The maximum release of sugars has come from all fruit substrata at 30% ethanol in the extractant. Results of biochemical analyses of extracts have shown that carrying out extraction in the way of double insisting on condition of selection of optimum: concentration of ethanol in the extractant, ratios of the raw materials/ extractant and the best time of insisting, allow to provide on average a 55-60% exit of nutrients from the studied fruit raw materials

MODERN TOOLS OF STATE REGULATION FOR AGRICULTURAL PRODUCTION
06.00.00 Agricultural sciences
Description
This article notes that agricultural production is not a self-regulating system. The article highlights specific features of agricultural production and forms of ownership of the major productive resource – land, ineffective policies of promoting development and introduction of innovative technologies. It is noted that the system of measures and tools of state regulation of agricultural production have two directions of influence: governmental regulation of the agricultural market mechanism and industrial governmental support for manufacturers. The authors give classification of methods and instruments of state regulation, liberalization of the agricultural sector in the WTO, levels of aggregate support for agriculture; as well as identifies the key growth areas of the governmental support and discusses the basic institutions of governmental regulation: ownership, legal Institute of economic management and the Institute of organization management. It's pointed out that the current dynamics of the development of agricultural production in our country is determined by four major external factors: the Institute of Western sanctions imposed against our country, Russia's integration into the international market by joining the World Trade Organization, the functioning of the Single Economic Space within the Customs Union, and the necessity of solving problems of import substitution and food security of our country. Implementation of these methods requires significant institutional transformation and transition into the new levels of legal, commercial, and economic regulation with observance of equitable international cooperation. In conclusion, the authors discuss an insufficient level of development stimulation in domestic agriculture
