Linear programming model is used to investigate the economic feasibility of utilizing stony lands for crop production in South-Western Quebec where stoniness is the major constraint. Results for the representative farms indicate that income variations are due to economies of size, differences in crop yields (experimental or farm level) and type of reclamation method used. The market values for stony lands (determined by regression technique) are higher compared with the productive values. Analysis also indicates that crop production is feasible within the parameters defined and that it is more economical to develop unutilized stony land rather than purchase prime agricultural land at current market prices. Parametric programming procedures indicate that the solutions are more sensitive to crop yields and prices than reclamation costs.

The article analyzes the current state of the irrigation and drainage systems of the Ryazan region. It is shown that the lack of technical operation of the drainage network led to its failure and failure to perform its functions. Irrigation, in spite of the fact that it gives stability in the years of droughts due to aging and the dismantling of machinery and equipment is not carried out. It is shown that for the reconstruction and / or modernization of irrigation and drainage systems it is necessary on the basis of inventory to determine the environmentally optimal and economically viable systems, their parts and structures that require rehabilitation, reconstruction and / or modernization. The decision to reconstruct may include not only the ameliorative system as a whole, but also some part of it, for example, a canal, pipeline or a separate hydraulic structure, taking into account the justification of economic feasibility. In dry periods, for the Meshcherskaya lowland and areas with peat soils, it is necessary to provide for land-reclamation systems for dual regulation of soil moisture, which reduces the possibility of peat ignition and the spread of fire. It should be borne in mind that the reconstruction of land-reclamation systems has its specific features, which include: socio-economic (increasing the productivity of agricultural land, obtaining additional income, creating modern infrastructure, increasing employment, living conditions, labor, etc.) ; ecological (creation of cultural landscapes, ensuring their ecological sustainability, prevention of land degradation processes, improvement of recreational conditions, elimination of waterlogging, flooding, salinization, erosion, etc.). Reclamation activities are carried out in compliance with the requirements of land, water, forestry legislation of the Russian Federation, as well as the legislation of the Russian Federation on the protection of the environment, on the subsurface, on the plant world and on the animal world.

Abstract The article examines the issues of agricultural production by the agrarians of the Russian Federation in the context of import substitution and their contribution to the formation of food independence in the region. The dynamics of agricultural production in such sectors as crop and livestock production has been analyzed. In recent years, thanks to new innovative technologies in crop production, there has been a positive trend towards an increase in gross harvest, as well as an increase in crop yields. So, in particular, for more than thirty years of the analyzed period of time, gross agricultural production increased by 6110.4 billion rubles, and in the sectors crop and livestock production there was an increase in production by 3276.8 billion rubles. and by 2833.8 billion rubles. These indicators were influenced by such innovative developments in crop production as binary crops, new varieties of agricultural crops, as well as a significant increase in the use of fertilizers on agricultural land.

Solonetz Soil

The solonetz soil cover 21.7 % of Novosibirsk Region, or 3 686.2 thousand hectares. In the Barabinsk lowland and northern Kulunda, solonetz soil is seen as agricultural land, as it doesn’t make solid massifs, but occur as small spots among zonal soils (black soils, meadow-black soils and black earth-meadow soils). Regardless the vast area, solonetz soils fulfil 20 - 25 % only of the needs of the livestock industry, which is caused by low productivity in the natural state (1.0 - 3.0 c/ha of dry matter in the steppe and 3.0 - 5.0 c/ha in the forest steppe). The authors outline the necessity to increase solonetz complexes fertility and therefore improve precision technologies of farming based on various methods of land reclamation such as chemical, agrotechnical and phytomelioration with adaptive-landscape farming systems that preserve soil fertility and crop yields. Agrobiological reclamation is based on layer-by-layer soil treatment performed once per rotation. This treatment includes milling or distillation of the upper solonetz layer with further deep nonmoldboard loosening, as well as application of dry resistant, salt resistant and solonetz resistant annual and perennial grasses into the crop rotation. These grasses extract easily soluble salts and ash elements from the soil. The research results show the effect of agrobiological melioration on solonetz soils of the Barabinsk lowland. The authors observed the decrease in the number of salts in the soil profile. Particularly, the number of carbonates and hydrocarbons decreased; that indicates slight effect of soda in the soil formation. The researchers observed variation in pH from 9.1 (in virgin variant) to 8.1 – 8.5 influenced by reclamation. Graded tillage and phytomeliorants applied in the crop rotation resulted in higher fertility of saline soils and their chemical parameters equal to the values of zone soil.

The Impact

A new United Nations sustainable development Agenda underlines the relevance of Organic farming development. In the same line the Government of the Republic of Lithuania seeks to create economically efficient and competitive agriculture, based on low environmental impact farming, to develop organic farming and high quality certified agricultural and food production, conserve natural resources. Transition to the sustainable agricultural development faces the main difficulty, which is formulated as a scientific problem: how to reconcile the economic and political interests? This research is carried out by the purpose to offer alternative possibilities for organic farming development. The research was carried out using mathematical programming model and scenario analysis. Model is formulated as a linear mathematical programming optimization model, consisting of objective function, constraints, expressed as inequalities and fulfilling non-negative values conditions. The model includes existing and results provide the maximum gross value added ensuring crop production structure, taking in to account farming practices applied in Lithuania: conventional, organic, organic in conversion and integrated. The analysis of three scenarios has shown that the majority of compensatory payments and prices of organic production (2013) are insufficient to increase organic crop area to the extent of 10 percent of total agricultural land in Lithuania by 2020: only by one third (31 percent) higher organic production prices, lead to reached 10.5 percent of organic crop area from the total agricultural land. The research results provide scientifically based knowledge to the policy makers about the impact of the policy measure “Organic farming” on the development of organic farming.

Abstract The formation of agricultural land use adequate to the tasks of the market economy is the most important task of the post-reform period. Agrarian transformations were of a social and political nature and solved the problems of transition from a planned to a market economy. To implement them, we used not the experience of Russia in previous years, but examples from the practice of advanced economies of the European Union. Therefore, the appearance of such a phenomenon as unused land (in general, characteristic of the crisis periods of the market economy) caused a negative perception. The paper considers this problem as an important social and economic phenomenon and suggests ways to solve it. For this purpose, the technology of identifying and detailed study of the state of the land is proposed. The identification of the natural suitability for the cultivation of the main agricultural crops is confirmed by ensuring sufficient efficiency of crop production. Based on the analysis of the conditions of land use (labor, capital and energy supply) and their legal status, the economic feasibility of involving unused plots in economic turnover is established. This will make it possible to make the necessary and reasonable decisions to restore the land and resource potential of agricultural production. To ensure the controlled and systematic implementation of the program to solve the problem, a state-commercial center is being created in the subject of the Federation, which organizes, controls and finances the activities carried out.

On Farm

In dairy farms, the feeding cost, which includes the expenses for purchased feed but also the expenses for feed production, constitutes a very large part of production cost (more than 60%), which indicates the economic importance of the feeding strategy. This study discerns three different feeding strategies: landless farms only purchasing feed from markets (“Purchasing”), farms for which home-grown feeds stand for more than 10% of feeding costs (“Producing”) and farms with less than 10% home-grown feeds (“Multi-purpose”). Based on technical and economic data from 47 dairy cow farms in Greece, alternative scenarios of development of the dairy sector are determined taking into account the dependence on on-farm feed production. Through a parametric programming model, the study provides insights regarding the optimal structure of the system under different scenarios (changing availability of variable capital, changes in milk prices). The results indicate that “Purchasing” farms are the preferred option when variable capital is abundant and milk prices are satisfactory, while “Producing” are the ones surviving with milk prices significantly lower than the actual ones in Greece and European Union. “Multi-purpose” farms perform worse than the other two and are sidelined in both scenarios, as they do not seem to be able to specialize in the dairy enterprise or in crop production and thus to minimize costs.

Abstract Reclamation is an effort to repair the damaged mining sector to provide optimal benefits. This review article aims to propose a natural product technology approach to the reclamation of post-coal mining land by increasing the content of soil organic matter so that the post-mining land becomes fertile and can be used for agricultural land. The method used is an observation and literature study. Literature searches were using them ScienceDirect, Scopus, PubMed, and Google Scholar databases. Land-use change of post-mining site to agricultural land provides prospective economic value to the community. However, the land quality of the post-mining area should be improved before food crop production. Tephrosia vogelii is a member of the Papilionoideae subfamily is important for land revegetation. They can fertilize the soil because of mutualistic symbiosis with the bacteria Rhizobium sp. which is capable to fix nitrogen in the soil and hence provide available nitrogen. Thus, the use of post-mining land as agriculture can improve the economy and sustainability as well as protect life and the environment with natural product technology.

The reestablishment of agroforestry systems in Central Asia, combining crop production with protective tree shelterbelts, provides significant potential to improve farming systems. This includes increasing crop yields, additional income from timber, as well as reducing soil degradation and wind erosion. Thus, adopting shelterbelts as a form of pro-environmental behavior provides a number of socio-economic benefits, although some trade-offs need to be considered as well. This paper investigates factors that shape the perception of—and attitude towards—the establishment of tree shelterbelts by farmers in two case study regions in Kyrgyzstan. Applying a conceptual framework distinguishing between extrinsic and intrinsic factors, research methods included semi-structured interviews with farmers and local policy makers. The results show spatial differences in the perception of shelterbelts, both on the regional and on the village scale. In general, shelterbelts were negatively perceived by more than half of the farmers. The main concern raised by farmers was the shading of crops by shelterbelts, resulting in a decrease of yield. In addition, small field sizes and potential conflicts with neighbors were key concerns. Furthermore, rules set by local self-government bodies were inconsistent with the legislative framework, posing significant restrictions to the adoption of sustainable land use practices.

Abstract Agriculture, crop production, analysis, statistics The aim of the study is to assess the state of the crop industry of the Republic of Buryatia and determine the directions of its. The efficiency of use of land resources, production of the main types of crop production, dynamics of crop yields were analyzed; directions of crop production industry development are determined. When preparing the article, methods were applied: comparison, index, relative and average values, graphic, etc., the empirical base is presented by the publications of the Territorial body of the Federal State Statistics Service for the Republic of Buryatia in agriculture, in particular on the crop industry. The results of the study show that the current level of production of crop production does not correspond to the modern needs of the republic. The constraints to the development of the industry are the low level of agricultural culture, frequent droughts, poor technical re-equipment, a small proportion of reclaimed land in the structure of agricultural land and others. Currently, the priority areas in the crop production of Buryatia are the production of feed to meet the needs of the livestock industry and the cultivation of grain crops.

Waste Soil

<p>The global expansion of infrastructures is generating vast amounts of waste soil (soil excavated from construction sites that cannot be used on-site); the amount of waste soil accumulated in the European Union in 2014 was estimated at 463 x 10<sup>6</sup> tons. The regulation and management of waste soil disposal are currently limited to: (1) local use for various engineering projects; (2) stockpiling on-site for future use; (3) transferal to landfills, which are currently overfilled, as padding material or for disposal. Despite a number of permitted actions for handling waste soil, a significant portion of it is disposed of in the area surrounding the construction site, thus raising the risk of pollution and landscape spoilage. Waste soils are commonly excavated from deep layers, and are therefore saline, sodic, and lack organic matter, preventing their use without pre-treatment. Moreover, due to the intensification of crop production, one-third of the global agricultural land area is susceptible to soil loss by erosion, constituting ~50% of total estimated soil erosion. Here we show a new approach for environmentally, agronomically and economically sustainable use of reclaimed waste soil to rehabilitate degraded agricultural land. In a 3-year field experiment under rain-fed conditions in a semi-arid region of Israel, we found that waste soil ploughed into agricultural soil had low erodibility, similar to that of the original agricultural soil, despite its high sodicity. Waste soil application tended to decrease the soil organic carbon concentration but had no detrimental effect on wheat hay yield or wheat grain yield or quality in the second and third year, respectively. The economic analysis suggested an average reduction of 8.7 million USD in waste soil disposal costs if 50% of the waste soil produced in Israel annually were to be utilized in agricultural fields. Thus, waste soil can be utilized successfully in degraded agricultural lands; this opens a new route to land reclamation and provides land managers and stakeholders with a sustainable way to reduce costs while transforming an environmental burden into a resource.</p>
