The structure of the cultivated areas serves as the basis for the system of crop rotation, the main link in modern farming systems. The structure of sown areas and the system of crop rotations as the fundamental links of the farming system have close direct correlations and feed-backs with all other links of the farming system. On the one hand, they are fundamental, first of all, for organizing the soil protection and nature conservation of the territory, since in each farm the sown areas of agricultural crops on arable land prevail over the area of other agricultural lands. On the other hand, the system of crop rotation, which is developed on the basis of the promising structure of sown areas, is the basis for other links of the farming system. For more efficient use of arable land, increasing the yield of major agricultural crops, meeting the needs of farms with crop production, improving soil fertility, it is necessary to change the structure of sown areas taking into account the specific agro-climatic conditions of the steppe zone. There are two subzones in the considered zone: arid and moderately arid one. We have substantiated and optimized the structure of cultivated areas in order to increase soil fertility, ecological balance and productivity of agricultural landscapes for these two sub-zones of the steppe zone. For the arid sub-zone, in the structure of sown areas, winter and spring crops should occupy 51.7%, legumes – 9.8%, fodder – 12.5%, industrial – 21%, vegetables – 5%. For the moderately arid sub-zone in the structure of sown areas, winter and spring crops should occupy 42.0%, legumes – 10.3%, corn for grain – 13.7%, fodder – 10.5%, industrial – 17.0%, vegetables – 5%, potatoes – 1.5%.

The Creation

Soil protection in agrolandscapes is especially necessary in conditions of intensification of production and increasing anthropogenic pressure on them. This complex should fit into the landscape farming system. The more intensive the load on the land in the farm, the higher the level of soil protection against destruction. The article notes that raising soil fertility, increasing crop yields and ecological environmental improvement are possible only on the basis of agrolandscape farming system, which allows to establish the correct ratio of arable land, meadows and forests. The transition to such a system of agriculture requires: development of a project for agrolandscape land management with a set of anti-erosion measures for each farm; adjusting the structure of sown areas taking into account market conditions, that is, increasing the area of productive crops in demand (winter and spring wheat, perennial grasses), which in combination with occupied and green manure pairs determine the structure of biologized crop rotation; widespread use of legumes (peas, vetch) as factors in the biologization of agriculture. The efficiency of expanding the area of perennial grasses to 25 % of arable land in some areas of the Non-Chernozem region and the Belgorod region is shown. Here, techniques that increase the efficiency of arable land are based on strict adherence to crop rotation with legumes, the use of adaptive varieties, and the use of biologized fertilizer and plant protection systems. It is noted that the creation of a system of shelterbelts makes it possible to reduce the cost of planting and growing them in comparison with single forest belts and what is very important for farmers is to sharply increase the return on their exploitation in the form of increased increases in crop yields. The creation of forest-sized landscapes will improve the environmental conditions for the cultivation of crops.

Landscape System

In the Russian Federation, solving problems of land use, land relations, and land policy leave the basis for social, environmental, economic, and overall political stability of the state. The area of the Belgorod region is 2713.4 thousand hectares, including arable land - 1654.4 thousand hectares (61 %), pastures - 347.6 thousand hectares (12.8 %), hayfield - 68.1 thousand hectares (2.5 %), forests and other lands - 316.5 thousand hectares (22.7 %). The area of eroded soils is 53.6 % of the entire territory of the region. They include: slightly washed out soils - about 35 %, moderate washed out soils - about 13 %, strongly washed out soils - 5.6 %, and flushed - about 1 %. According to Belgorod agrarian scientific center of the RAS area of eroded lands in the Belgorod region has increased in the Western natural-agricultural zone - by 5.1 %, in the Central - by 8.4 % and in the South-East - by 9.1 % over the last 3040 years. Currently, the concept of adaptive landscape farming has been developed, which provides for comprehensive measures to prevent soil degradation and create environmentally sustainable agricultural landscapes. Adaptive landscape soil protection system of agriculture provides for expansion of perennial grasses up to 25 %, introduction of leguminous crops and annual grasses in crop rotations. With a reduction in the use of mineral and organic fertilizers in modern economic conditions, it is impossible to achieve a balance of humus acceptable for sustainable development of the studied agricultural landscape. System of agriculture adapted to local landscapes provides for introduction of the whole complex of soil conservation measures which can stop land degradation caused by soil erosion. Introduction of adaptive landscape system of agriculture in the pilot farm of the Belgorod agricultural research center allowed to minimize erosion processes, stabilize soil fertility, and significantly improve economic indicators and energy efficiency of agriculture in the economy. The area of arable land was slightly reduced, and the area of forest belts and soil protection crop rotations increased. The average yield of grain crops and sugar beets increased greatly, the use of organic and mineral fertilizers increased significantly, their payback improved, and the crop industry became profitable and cost-effective. Only through adaptive landscape agriculture it is possible to stop water erosion, create conditions for stabilizing and increasing soil fertility, ensure the biologization of agriculture and increase its economic efficiency. Ultimately, this will increase production of domestic agricultural products and increase Russias food security.

In OOO “Dubovitskoe” which was organized in 2006 as investment project of the AO “Shchelkovo Agrokhim” for 2010 – 2012 three advanced crop rotations have been developed. Before their introduction the grain crops fraction in the cropping system was 62%, then it fell to 49%. At the same time the portion of raw crops increased from 15 to 20%, legumes from 6 to 8%, others (buckwheat, grain maize, etc.) - up to 23%. As of 2017, the crops of leguminous crops have increased noteworthily. There are two predominant soil types here heavy clay loam podzolized chernozem (6615 ha) and grey forest soil (856 ha). Weighted average indicators (as of 2017): humus content in the soils of arable land is 5, 34%; acidity pH is 4.92; labile phosphorus - 111.8 mg / kg soil; exchange potassium - 144 mg / kg soil. The coefficient of the soil fertility in the enterprise (weighted average) is 0.66. This means that maintaining and increasing the soil fertility for arable land of the enterprise is critical task. As a result of the research, it has been established that the technologies introduced in the crop vegetation management (CVS) in the crop rotation conditions ensure high productivity of cultivated crops and stability of humus content in soils as an energy basis and a guarantor of increasing fertility. The indicators of the labile phosphorus Р205 and exchange potassium К20 in the soils depending on the crop rotation vary from a certain decrease to expressed steady growth. Therefore it is necessary to specify seeding rates based on actual data. Sustainable soil acidification in the crop rotations under crop cultivation in OOO “Dubovitskoe” it is the result of the acid feterlizers high rates application, during studying period did not carried out required agromelioration with calcium contenting elements.

Purpose: to establish the basic principles of the organization of reclamed agricultural landscapes and to substantiate the use of the agricultural landscape approach in the organization of the territory. Materials and Methods. When preparing this article, the materials of Russian scientists dealing with the issues of soil fertility conservation and ecological sustainability of reclaimed agricultural landscapes were considered. The methods used were analysis, generalization, synthesis and other methods of working with literary sources on this issue. Results. In performing the work, the main principles and indicators were determined, such as productivity, sustainability, the rule of transforming measures for the natural environment, optimization of the agricultural landscape, authenticity, principles of the formation of reclaimed agricultural landscapes, the complexity of the reclamation impact, the required diversity, the uniqueness of the reclamation impact. The basic requirements for the preservation of soil fertility of reclaimed irrigated agricultural landscape have been established. It was found that to maintain ecological balance within the irrigated agricultural landscape, it is necessary to adhere to the indicators of the reclamation load of the natural environment. The limits of agricultural lands saturation in reclaimed agricultural landscapes for various agro-climatic zones have been substantiated and recommended. Conclusions. It has been determined that the coefficient of reclamation loading of irrigated lands, showing the maximum share of irrigated lands that can be irrigated in a particular climatic zone, varies from 0.3 in the forest-steppe zone to 0.60–0.85 in the semi-desert and desert zone. This suggests that with an increase in moisture supply, this indicator decreases, the recommended amount of agricultural land in various agroclimatic zones varies from 30 to 87 %, while the area of arable land should not exceed 20–25 % in a very dry zone, and with an increase in moisture supply, it can increase up to 80 % in the semi-arid zone. The amount of irrigated land in the reclaimed agricultural landscape should not exceed 18–20 %. Irrigated meadows and pastures should account for 1–2 to 5–6 % of the area.

Fava Bean

<p>Including legumes in intercropping systems may be regarded as a sustainable way to improve soil quality, fertility and land productivity, mostly due to facilitation processes and high rhizospheric activity which can mobilize soil nutrients for plants. Improvements in production and soil quality depend on inherent soil properties, climatic conditions, adopted management practices and fertilization, among others. The aim of this study was to assess the effect of the association between broccoli (Brassica oleracea var italica) and fava bean (Vicia fava) grown under different intercropping patterns on crop production, soil organic carbon (SOC), total nitrogen (Nt), soil aggregate stability (SAS) and soil fertility, compared to a broccoli monocrop. We defined a randomised block field experiment with three replications assessing the effect of monocropping, row 1:1 intercropping, row 2:1 intercropping and mix intercropping, with 30% reduction in fertilization in intercropped systems compared to monocrop. Soil sampling took place at harvest in February 2019. Results showed that the broccoli-fava bean intercropping significantly increased the general land production, with similar broccoli yield of 20000 kg ha<sup>-1 </sup>in all treatments, plus 8000 kg ha<sup>-1</sup> coming from fava bean. Crop diversification and fava bean cultivation even in monocrop significantly increased SOC and Nt compared to broccoli monocrop. SOC and Nt were 1.06% and 0.09%, respectively, for broccoli monocrop, while they had average values of 1.29% and 0.12%, respectively for the intercropped systems. SAS was also significantly affected by crop diversification, with increases in the proportion of the macroaggregates (size >2 mm) with intercropping. Broccoli monocrop showed an average proportion of these macroaggregates of 9.19%, while they increased up to 17.51% in intercropped systems. CEC was not significantly affected by intercropping SAS showing almost same percentage of aggregates independently of the treatment. Available P significantly increased in intercropped systems, likely due to increased microbial activity with the simultaneous growth of the two crop species. However, no significant effect of intercropping was observed with any other nutrient (Ca, Mg, K, Mn, Cu, Fe, Zn and B), suggesting that microbial communities activated by the crop association are highly related to P mobilization but not so intensively involved in other nutrients. Thus, intercropping systems like broccoli-fava bean association can be regarded as a viable alternative for sustainable crop production while increasing soil fertility despite reducing the addition of external fertilization. However, more crop cycles are needed to confirm this trend.</p>

Agriculture Sector

Agriculture is the most important sector of Indian Economy. Indian agriculture sector provides employment to 50% of the countries workforce. India is the world's largest producer of pulses, rice, wheat, sugarcane, pomegranates etc. The current scenario of agriculture business in India is not up to the mark as expected. There are number of reasons which causes less yield in the agriculture such as unpredictable environmental conditions, excess use of fertilizers (cost is increasing day by day), increased draught frequency and its severity, increasing labor rate, less difference between the income and expenditure, ripeness of soil, influenced suspensions, non-appropriate water management, diseases on crops, invasion of animals and so on. There is need to find the ways which makes the use of Information Technology (IT) concepts and tools wherever possible for increasing automation in the agriculture business, which results in the efficient and effective outcome of agriculture i.e. higher yields. The production efficiency can be increased significantly with technological advancement in agriculture. Internet of Things (IoT) is a novel design approach for precision farming. Farming has seen number of technological transformations in the last decade. By using various smart agriculture gadgets, farmers have gained better control over the process of raising the growing crops and livestocks. One of the major issues which cause fewer yields is the soil health. This paper mainly analyses/reviews the problems related to the soil health (soil fertility), which is a main obstacle in the crop production. Also this study focuses on the use of IoT applications in precision farming. It gives an overview of the relation between crop productivity and soil health

Results of researches of efficiency in short crop rotation with busy steam are given in this article. Researches were conducted in the Omsk district of the Omsk region on typical black soil, with the maintenance of humus of 6.7% (in a layer of earth of 0-30 cm).  Cultivation of field cultures against the background of application of means of chemicalixation was carried out in a crop rotation the occupied steam (green manure) – wheat – barley – oats. During the conducted researches the quantity and dynamics of moisture, the maintenance of the main macrocells in the soil, and efficiency of all crop rotation was defined. The received results allow to draw a conclusion that in a crop rotation with busy steam and four fields at application of means of chemicalixation the increase of a harvest of the first wheat for 45.2%, barley repeatedly 31.5% and oats for 9.9% is noted. Application of fertilizers, at the rate of N30P30 on 1 hectare of an arable land, and herbicides, provided increase in productivity grain on 0.53 t/hectare, an exit of grain of 0.44 t/hectare, and feed-protein units to 1.29 t/hectare. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia.

Peculiarities of natural conditions of the territory of Ukraine have historically determined mainly the agricultural use of its lands, the indirect consequence of which was the formation of agro-landscapes as a specific form of spatial realization of anthropogenic activity. The study of agrolandscapes, a comprehensive assessment of their condition and development trends, development and implementation of adequate land management solutions are a key task to avoid degradation, especially arable land. In the context of the above, the shortcomings of modern proposals and indicators for assessing the state of agricultural landscapes and their land management are considered and identified. Concerns about the recommendations of domestic scientists and practitioners to transform about 12 million hectares of arable land into other lands are justified. The motivation for this decision was the idea of excessive plowing of the territory of Ukraine, although world experience provides positive evidence of successful agriculture, even under such conditions. Allegations of insufficient study of the problem of land management formation of sustainable agrolandscapes are given. It is proposed to use the term "sustainable" for the agro-landscape, the state of which corresponds to the ecological and social-industrial conditions of land use. Systematic analysis of the structural components (lands) of the agro-landscape revealed the significant role of their interaction in creating and maintaining a microclimate favorable for crop production in adverse natural conditions. The legitimacy and expediency and practical efficiency of using the spatial-functional method of land management formation of the stability of agro-landscapes are substantiated.

The article presents the results of the agroecological composition of soils for different agricultural uses. Under modern conditions of increasing intensification of agricultural production, the agroecological condition of soils is deteriorating, which increases the risk of obtaining low–quality products. Along with this, there are various problems, such as loss of soil fertility, increased erosion, groundwater pollution and environmental pollution in general. Therefore, there is a need for constant monitoring of agroecological indicators of the soil in the conditions of intensive agriculture and horticulture. The great importance is the problem of finding reserves to increase soil fertility and improve their agroecological condition. Therefore, regular testing of soil nutrients and factors that have a major impact on their availability are extremely important to achieve sustainable levels of crop and fruit production. The main purpose of the research was to study and analyze agricultural lands: arable land and perennial plantations and the main agrochemical indicators of the soil of the central part of Vinnytsia region during intensive agriculture and horticulture. The object of research is the soils of agricultural lands used under intensive horticulture and crop production. The subject of research is the agroecological indicators of soil. The research was carried out in the farm of Agro–Etalon LLC in the village of Vasylivka, Tyvriv district. The soils of agricultural lands used under orchards (apple orchard) and agricultural crops (wheat after sunflower predecessor) were studied for comparison. According to the results of soil analysis, it was found that the highest difference in the studied indicators was found in the exchangeable potassium (К2О), mobile phosphorus (Р2О5), which was observed more in the soils involved in horticulture compared to the soils of field crop rotations. Farm soils with different agricultural uses were characterized by lower humus content. The highest difference in the concentration of chemical metals was found for molybdenum (Mo) and cadmium (Cd), which were more in the soils used in horticulture.
