The paper describes the mechanism of changes in wall ceramics physical-mechanical properties and structure when additives of various types and quantities are doped. The authors come to the conclusion that composite modifications of ceramic mixtures improve their molding properties, reduce the firing temperature for 150-20007deg;C and increase resistibility and frost resistance of end products. These composition additives consist of crushed glass fine powder mixed with oil sludge in 1/5 proportion. The paper proves that these composition additives 30-35% reduce energy consumption in wall ceramics production and provides wall ceramics of high quality for civil and industrial engineering. © 2015 The Authors.

As in old times today the formation of a reliable, well-balanced fodder base add the reduction of fodder nutritive value during the gathering is to the great extend determined by the proper organization of fodder production and conservation. The creation of high-value fodder base for the development of breeding depends both on the proper selection of crops and their biological peculiarities. Thus in the investigations we studied the biological peculiarities of growth and development, capacity formation of different crops of pure and mixed sowing. As the result of these investigations we have obtained the data? Which allow us to estimate the capacity of feed crops of pure and mixed sowing in soil and climatic conditions of West-Kazakhstan region for using in innovative techniques of production of fodder protein?

The centuries of human impact on ecosystems caused the appearance and progressive growth of the processes of degradation and desertification, which have now become global in nature. Now these areas account for approximately 145 million ha of irrigated land, 170 million ha of rainfed arable land and 3.6 billion ha of pastures. There are about 860 million people here, or almost 20 % of the world's population. As a result of an active human impact on the environment there is a constant change in its ecological status, mainly to the downside. Such adverse changes include the processes of degradation and desertification, caused by the adverse natural preconditions, and, above all, by the unsustainable economic activities in very «fragile» and easily «vulnerable» ecosystems. The article presents the results of a research which was made in the semidesert zone, and was monitoring the processes and factors of degradation of soil and vegetation cover of the grassland of Zhangalinsky area of West Kazakhstan. However, an important task for humanity is the prevention of degradation and restoration of lands disturbed in a process of degradation and desertification. In the semi-desert zone of West Kazakhstan region, one of the ways of improving the condition of devastated and degraded land and improving the efficiency of forage production is the restoration of bio-resource potential of the grassland. Thus, for the improvement of conditions of hayfields and pastures there is a high importance of a correct selection of single-species perennial grasses and their mixtures. The article also contains the results of the research, allowing estimating productivity of perennial grasses in single-species, mixed crops in the conditions of semi-desert zone of West Kazakhstan region to restore the bio-resource potential of degraded meadows and pastures. The research has established the highest productivity of grass mixtures with the participation of Yellow sweet clover and Wheatgrass (0,60-1,03 t/ha of dry weight) compared with a single-species crops of these perennial grasses of a hay use. In a pastures among the perennial grasses the most productive were a single-species crops of Wheatgrass (0.55 to 0.77 t/ha of dry weigt). © 2010 RJPBCS. Source

The studies conducted have provided data enabling one to evaluate the productivity of feed crop in the frontier zone of the West Kazakhstan Province of the Republic of Kazakhstan and the Saratov region of the Russian Federation for use in innovative technologies on feed protein production. The studies have ascertained the feasibility of cultivation of sorghum, Sudan grass and millet agrophytocenoses in the noted frontier zone instead of the conventional barley crops. Suggested croppers are distinguished by active photosynthetic activity. Over the 5-year period the average maximum leaf area of sorghum crop makes 52.0 thousand m2/ha, crop of Sudan grass and coarse millet generate 46.0 and 42 thousand m2/ha, respectively. And in the barley crop it does not exceed 23.6 thousand m2/ha. Studied agrophytocenoses of annual forage crop differ by yield of fodder units, digestible protein, feeding protein units (FPU) per unit of land, and the accumulation of the metabolic energy. Over 5-year study period, the highest yield of green mass was provided by sorghum and Sudan grass crop-26.1 t/ha and 16.2 t/ha, respectively. Productivity of barley was significantly inferior to sorghum and Sudan grass, accounting for just 12.0 t/ha. Source

In recent years the strengthening of anthropogenic impact onto an arable land, an unsystematic use of land and the lack of measures to preserve the fertility have led to the intensive soil degradation. In this regard, the priority direction was the increase of in the plant growing productivity and quality of crops while preserving the soil fertility by the biological factors activating that do not violate the natural essence and the ecological balance of agro-ecosystems. With the comprehensive research we could find an influence of organic fertilizers (animal manure, a straw, green manures) on the crop yields. In the conducted researches we have studied the dependence of crop yield on the conditions of their moisture provision, agrophysical and agrochemical indices of the dark chestnut soil. Source
