The worldwide importance of soybean and the main limitations to crop yields. Because of its potential for large-scale production, soybean (Glycine max (L.) has excelled in the world agricultural economy as a major oilseed crop. At present, soybeans are grown primarily for oil extraction and for use as a high protein meal for animal feed. Soybean has a protein content of approximately 40% and an oil content of approximately 20%. This crop is currently being produced around the world. Indicate that to obtain increases in soybean yields, it is necessary to understand the interaction between cultivars and the production environment. Based on these factors, crop management can be adjusted to achieve proper development of plants in each production environment. Soybean is very responsive to environmental conditions, and the main climatic factors affecting its crop yields include the photoperiod, which influences the availability of full light, temperature and water availability. Although the effects of various environmental factors interfere with the performance of crops, water restriction is the main limiting environmental factor that contributes to the failure to obtain maximum soybean yields influencing the use of other environmental resources. Two-thirds of world food production through cultivation occurs under water stress. In this context and because of the prospect of global climate change, most crops will be exposed to negative impacts caused by drought.

Abstract Continuing consumption of fossil fuels around the world, which has led to an increasing concentration of carbon dioxide CO2 in the atmosphere and global climate change caused by greenhouse gases, has become one of the main challenges for humanity. Heterogeneous catalytic hydrogenation of carbon dioxide in order to obtain valuable carbon-containing products and materials is one of the decarbonization directions. There is much research in the world dedicated to the hydrogenation of CO2 to various hydrocarbons, such as methane, lower olefins, long-chain hydrocarbons, formic acid, methanol and higher alcohols, which are produced by catalytic reactions with various mechanisms. There are still significant challenges associated with the need for an external source of hydrogen, high process temperatures, and the development of active, selective, and stable catalysts that would be suitable for large-scale production. This paper presents results of research on a CO2 utilization method with hydrogen and hydrocarbons production – the transformation of wastes into a source of energy, which allows solving environmental and energy problems. The method described in this paper consists in the interaction of metallic fillers with water saturated with carbon dioxide in a reactor at low (room) temperatures and further analysis of the resulting gas mixture using a chromatograph. Qualitative and quantitative evaluation of the produced gas composition, study of the effect of reaction system volume, filler composition and structure, and process temperature on the reaction product yield are presented. The results of theoretical and experimental analysis of the reactions underlying the process are given, and the economic potential of the proposed laboratory method is evaluated.

Abstract. Large-scale production of feedstock crops for biofuels will lead to land-use changes. We quantify the effects of realistic land use change scenarios for biofuel feedstock production on isoprene emissions and hence atmospheric composition and chemistry using the HadGEM2 model. Two feedstocks are considered: oil palm for biodiesel in the tropics and short rotation coppice (SRC) in the mid-latitudes. In total, 69 Mha of oil palm and 92 Mha of SRC are planted, each sufficient to replace just over 1 % of projected global fossil fuel demand in 2020. Both planting scenarios result in increases in total global annual isoprene emissions of about 1 %. In each case, changes in surface concentrations of ozone and biogenic secondary organic aerosol (bSOA) are significant at the regional scale and are detectable even at a global scale with implications for air quality standards. However, the changes in tropospheric burden of ozone and the OH radical, and hence effects on global climate, are negligible. The oil palm plantations and processing plants result in global average annual mean increases in ozone and bSOA of 38 pptv and 2 ng m−3 respectively. Over SE Asia, one region of planting, increases reach over 2 ppbv and 300 ng m−3 for large parts of Borneo. Planting of SRC causes global annual mean changes of 46 pptv and 3 ng m−3. Europe experiences peak monthly mean changes of almost 0.6 ppbv and 90 ng m−3 in June and July. Large areas of Central and Eastern Europe see changes of over 1.5 ppbv and 200 ng m−3 in the summer. That such significant atmospheric impacts from low level planting scenarios are discernible globally clearly demonstrates the need to include changes in emissions of reactive trace gases such as isoprene in life cycle assessments performed on potential biofuel feedstocks.

With the globalization and rapid development every filed is taking an increasing interest in physical geography and human economics. There is a surging demand for small scale world map in large formats all over the world. Further study of automated mapping technology, especially the realization of small scale production on a large scale global map, is the key of the cartographic field need to solve. In light of this, this paper adopts the improved model (with the map and data separated) in the field of the mapmaking generalization, which can separate geographic data from mapping data from maps, mainly including cross-platform symbols and automatic map-making knowledge engine. With respect to the cross-platform symbol library, the symbol and the physical symbol in the geographic information are configured at all scale levels. With respect to automatic map-making knowledge engine consists 97 types, 1086 subtypes, 21845 basic algorithm and over 2500 relevant functional modules.In order to evaluate the accuracy and visual effect of our model towards topographic maps and thematic maps, we take the world map generalization in small scale as an example. After mapping generalization process, combining and simplifying the scattered islands make the map more explicit at 1 : 2.1 billion scale, and the map features more complete and accurate. Not only it enhance the map generalization of various scales significantly, but achieve the integration among map-makings of various scales, suggesting that this model provide a reference in cartographic generalization for various scales.

Large fluctuations in crude oil prices and the diminishing oil supply have left economies vulnerable to energy shortages thus placing an enormous pressure on nations around the world to seriously consider alternative renewable resources as feedstock in biofuel applications. Apart from energy security reasons, biofuels offer other advantages over their petroleum counterparts in that they contribute to the reduction in green- house gas emissions and to sustainable development. Just a few decades after discontinuing its large scale production of bioethanol for use as en- gine fuel, South Africa (SA) is again on its way to resuscitating its biofuel industry. Herein an overview is presented on South Africa’s oilseed and biofuel production, biofuels industrial strategy, industry readiness, chal- lenges in switching to biofuels and the strategies to overcome potential obstacles.

Soils are one of the most important, basic resources that is essential for the creation of a large number of goods and services that are an integral part of the ecosystem and human well-being. Soils, both actively used and others, provide ecosystems services which are important for regulating of the global climate and for large-scale regulation of various natural resources. About 33 % of global soil resources are degraded due to erosion, pollution, compaction, salinization, acidification, dehumidification and other adverse processes associated within appropriate management of ground water resources. About 33 % of global soil resources are degraded due to erosion, pollution, compaction, salinization, acidification, dehumidification and other adverse processes associated with inappropriate management of soil resources. Excessive lowing of the land fund, non-compliance of modern agricultural systems, neglect to agronomic land use norm sand ecology, lack of proper system of soil fertility management contributes to the development of degradation processes. The degradation is almost inevitable companion of humanity for many centuries of its development. Of course there are differences in this process, and they depend on the level of development of society, the understanding of the patterns of soil formation, and the state of the economy. Providing the rational, scientifically grounded use of soil, Ukraine, possessing a huge reserve of soil fertility, may be one of the world leaders in the production of high-quality food products. However, unfortunately, the soil does not occupy a privileged position in society. It is considered exclusively from the utilitarian side as a means of getting of agricultural products. The most important thing for the survival of humanity is the attitude of people to the soil, which is formed by culture, economic and social system of society. In the modern world, when the interconnection of elements in the mechanism of the world economy intensifies and the number of the population is steadily increasing, the management of soil resources plays more important role than ever before. Societies that have almost exhausted their environmental potential are often forced to maximize their crops to feed the population, regardless of the depletion of the soil and the need to protect and preserve it for next generations. Key words: soil, degradation, use of the soils, fertility, ecological crisis, society, soil area.

The article examines the current tendencies of entering the oil and fat subcomplex of Ukraine intothe world markets. It has been revealed that oil crops and their products are the main export commodity inagro-food export of the state. The large scale production of the sub-complex products, with modest domesticconsumption, is first and foremost associated with successful integration into international trade. Foreigntrade thus becomes an important factor in the development of the subcomplex. Considering the complexityand multidimensionality of the problem, the main segments of the market - oilseeds, oils and oilcake - arehighlighted in the research. On the basis of statistical data, the analysis of export volumes, dynamics, position on the world market and opportunities for their strengthening were made. It has been established thatUkraine, as a powerful producer and active participant in the world market, influences, to some extent, theexcess of world production over consumption of oil and products of their processing, which leads to a decrease in export prices and, as a consequence, to a loss of export earnings of domestic exporters. The studysubstantiates the need to improve the structure of production of oilseeds, the balance of use of soybeansand rapeseed, constant monitoring of the situation in foreign markets.

Abstract An acidic thermostable xylanase (AT-xynA) which was stable at low pH and high temperature was considered to have great potential in animal feed. For large-scale production, AT-xynA activity was enhanced about 1-fold in Pichia pastoris by constructing a double-copy expression strain in this study. Furthermore, impacts of different AT-xynA levels on growth performance, nutrient digestibility, short-chain fatty acids, and bacterial community in weaned piglets were determined. Compared with the control group, ADFI and ADG were higher for the pigs fed 4,000 or 6,000 U/kg AT-xynA (P < 0.05). AT-xynA supplementation also significantly increased the digestibility of OM, GE, and DM (P < 0.05). AT-xynA supplementation increased the concentrations of acetate in ileal (P < 0.01) and cecal digesta (P < 0.05). Isobutyrate (P < 0.05) and valerate (P < 0.05) concentrations in colonic digesta also significantly increased compared with the control group. AT-xynA supplementation increased the abundance of Lactobacillus in the ileal, cecal, and colonic digesta of weaned piglets (P < 0.05). AT-xynA alleviated anti-nutritional effects of nonstarch polysaccharides (NSP) by preventing the growth of Pateurella and Leptotrichia in the ileum (P < 0.05). AT-xynA increased the abundance of NSP-degrading bacteria, such as Ruminococcaceae, Prevotella in the cecum and colon (P < 0.05). In summary, AT-xynA addition could improve the growth performance of weaned piglets by altering gut microbiota.
