The aim of the research is to investigate technological process of growing of 9 promising soya cultivars, obtained from 5 originators, in dry steppe zone of Volga region (Saratov area) under irrigation. Experiment observations were done in 2012-2014 in accordance with standard techniques of experimental work and schedule of study. The experiment investigations were carried out through all elements of technological process.
The reform of the 90s led to the elimination of states monopoly of landownership and to the privatization of most agricultural lands. Within the small auxiliary sector of agricultural land the turnover arose in the early reform. But in the large agro-industrial sector, the turnover of lands received the necessary legal regulation only in 2003 (more than 10 years later than the mass privatization of these lands). For this type of turnover, a significant part of the regulatory mechanisms was borrowed from foreign experience, because the domestic experience was absent.
Studied was the impact of phosphogypsum and phosphogypsum-containig amendments on the properties of ordinary chernozem degraded due to irrigation with mineralized water (1.7-2.0 g/l), as well as on the crop yield. It was established the decreasing of soil sodicity by 50% upon applying the total calculated dose of phosphogypsum (10 t/ha), the increasing of calcium content in soil exchangeable complex up to optimal parameters (85%), the achieving of good water-stability of soil.
The estimates of emission and absorption of carbon dioxide and other greenhouse gases obtained according to the requirements of the Intergovernmental Panel on Climate Change with using methodology of the Center for forest ecology and productivity RAS are represented. The calculations were made for the managed forest lands distinguished in the territory of the Russian Federation Forest Fund (the 74% of forest land). From 1990 to 2009, managed forests were sinks for carbon dioxide from 231.5 mill. t of CO2 in 1990 to 700.8 mill. t of CO2 in 2009.
On the basis of legislative norms concerning land and nature management in Russia and scientific concepts of soil and land, new definitions of these basic concepts are suggested. Soils and lands are considered as separate components of the environment, each performing their own ecological functions. The definitions for land degradation and soil degradation are given.
Substantiated was the use of formal methods in the development of adaptive-landscape farming systems. The study was conducted in the Tver region. The article proposes to determine the values of macroagrogeosystem production potential (PP) by calculating integrated productivity parameters of different locations. There were distinguished 11 types of landscapes within the Tver region. The values of integrated indices were calculated.
The discussion paper 40 represents the results of an analysis for determining influencing factorson profits and profitability of Russian enterprises in the region of Omsk. Based on the finalyearly reports of the enterprises it is shown, that in Russia five earning ratios can be distinguished:the gross profit, the profit on sales, the profit before taxes, the profit on ordinaryactivity, and the net profit. The gross profit and the profit on sales are similar for all testedenterprises. Therefore, in this article only the gross profit, or the profitability of the grossprofit are discussed.
For the first time assessment and mapping of desertification have been performed in Russia at the 1 : 2500000 scale using data of geometrical sounding of the earth and in accordance with the approaches recommended by the United Nations Convention to Combat Desertification (UNCCD). It is shown that desertified areas, areas experiencing desertification, and areas threatened by desertification occupy about 1250000 km2. Nineteen causes of changes in natural and natural-artificial systems, seven degradation trends, and three progradation trends are recognized.
This paper discusses the economic implications of the preferential trade agreements that New Zealand is currently negotiating, using a computable general equilibrium modelling framework. The New Zealand dairy industry is a particular focus in the results, which come from the GTAP model produced by Purdue University.
Assessing the value of the state support for the agriculture is important for solving the problems of regional and federal agrarian policy. In the result of calculations carried out under the state support assessment procedure of the Organization of Economic Cooperation and Development (OECD) based on comparing domestic and world (reference) process for products and resources inadequate conclusions on the support of agriculture in Russia and its agrarian policy are made.
