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.

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%.

Emission Of Greenhouse Gases

Planned crop rotation offers a pragmatic option to improve soil fertility, manage insect pests and diseases, and offset the emission of greenhouse gases. The inclusion of legume crops in crop rotations helps to reduce the use of external nitrogen inputs for legumes and other crops because legumes may fix the atmospheric nitrogen. This also helps to reduce the environmental pollution caused by volatilization and leaching of applied nitrogen. The inclusion of allelopathic crops in rotation may be useful to suppress noxious weeds due to release of the allelochemicals in the rhizosphere. The rotation of tap-rooted crops with shallow rooted crops may result in efficient and productive use of nutrient resources and conservation of soil moisture. Continuous monoculture systems may cause the loss of biodiversity. Land fallowing is an efficient agricultural management technique mostly practiced in arid regions to capture rainwater and store it in the soil profile for later use in crop production. During fallowing, tillage operations are practiced to enhance moisture conservation in the soil. Keeping soil fallow for a season or more restores soil fertility through nutrient deposits; increases organic matter, microbial carbon, and soil microbial diversity; and improves the soil’s physical properties, including aggregation stability and reduced soil compaction due to decreased traffic. In addition, fallowing of land provides biological means of pest (weeds and insects) control by disrupting the life cycle of pests and decreasing reliance on pesticides. Land fallowing can help offset the emission of greenhouse gases from agricultural fields by reducing traffic and increasing carbon sequestration within the soil. Summer fallowing may help to preserve moisture in diverse soil types in the rainfed regions of the world, although it may reduce the carbon sequestration potential of soils over the long term. Energy resources are decreasing, and the inclusion of energy crops in crop rotation may be highly beneficial. Many of the processes, factors, and mechanisms involved in crop rotation and land fallowing are poorly understood and require further investigation.

Energy Flows

The purpose of the study is to determine the suitability for making sound decisions on the reproduction of soil fertility of the following quantitative laws of the methodology for managing material and energy flows in crop rotations: the energy content of 1 ton of humus (in GJ) is equal to half the nitrogen contained in it (in kg); the amount of exchangeable energy (in GJ) in 100 kg of phytomass is equal to the halfsum (in kg) of nitrogen and phosphorus pentoxide (about 2/3 of it falls on nitrogen). The approbation was carried out on the data of long-term stationary experiment. The results are as follows: with an increase in the level of fertilizer, nitrogen removal with the yield increased by 30–40%, and that of phosphorus by 6–12%; due to doubling the manure rate and the use of mineral fertilizers, the phosphorus balance became positive, and the nitrogen one remained negative, but improved by 17–28% depending on the type of a crop rotation. The deviation of the calculated balance of the exchangeable energy from the actual one on the poorly and most richly fertilized backgrounds was -5.5 to -11.9% and 3.0 to 8.6%., respectively.

Methodological Approaches

The article deals with the issues of the management of soil fertility based on the application of two methodological approaches to arable land normative monetary evaluation (NME). These researches have been conducted on the results of economic activity of the Poltava region agrarian enterprises of Ukraine. The differences between the two methodological approaches to the calculation of the NME of arable land in the Poltava region are shown. These approaches, namely, on cereals and on five agricultural crops, presuppose the calculation of the NME of arable land on the basis of capitalized rent income. The approaches are similar to the Ricardian model of land pricing, which is being widely used with its various modifications in different countries of the world. Our own methodology for analyzing the approaches to the NME of arable land, based on the developed stochastic harmonic models (SHM), is represented in the article. The application of the two methodological approaches to the calculation of the NME of arable land in the Poltava region of Ukraine, which presupposes its consideration on the data concerning cereals and five agricultural crops, revealed essential differences between them in the course of the conducted economic-mathematical analysis. It has been found that the methodological approach on cereals has a lower level of the explanatory attribute variation (of humus content in soils) compared to five agricultural crops. That finally leads to the essential difference in the optimum values of the arable land NME at increasing humus content in soils. Thus, the optimum value of the arable land NME within the second methodological approach is twice as much as within the first one. The measures to improve the arable land NME, based on the data of the Poltava region and can be successfully used all over Ukraine, as well as in many countries of the world. The advantages of applying the methodological approach based on five agricultural crops were studied and grounded in the current research. This approach proves the dependence of arable land NME on the humus content and enables higher objectivity for effective and rational management of soil fertility.

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

The use of nitrogen fertilizer is becoming a global problem; however continuous fertilization with nitrogen ensures large and constant harvests. An 8 year research (2006–2013) was conducted to evaluate the relationships between differently fertilized cultivated plant rotations. The research was conducted in Lipliunai (Lithuania) in the agroecosystem with nitrogen metabolism in fields with deeper carbonaceous soil, i.e. Endocalcari Endohypogleyic Cambisol (CMg-n-w-can). The research area covered three drained plots where crop rotation of differently fertilized cereals and perennial grasses was applied. Samples of soil, water and plants were investigated in the Chemical Analysis Laboratory of the Aleksandras Stulginskis University certified by the Environment Ministry of the Republic of Lithuania. The greatest productivity was found in a crop rotation with higher fertilization (N32-140). In crop rotation with lower fertilization (N24-90) productivity of cereals and perennial grasses (N0-80) was 11–35 % lower. The highest amount of mineral soil nitrogen was found in cereal crop rotation with higher fertilization. It was influenced by fertilization and crop productivity. The lowest Nmin and Ntotal concentrations in drainage water were found in grasses crop rotation. Crop rotations of differently fertilized cereals increased nitrogen concentration in drainage water. Nmin concentration in water depended on crop productivity, quantity of mineral soil nitrogen, fertilization, and nitrogen balance. The lowest nitrogen leaching was found in the crop rotation of grasses. Cereal crop rotation increased nitrogen leaching by 12–42 %. The usage of all crop rotations resulted in a negative nitrogen balance, which essentially depended on fertilization with nitrogen fertilizer.
