On the example of the territory of the Altai Krai, the article traces the consequences of destruction of the natural landscapes structure, the creation of artificial elements of their ecological framework of agricultural landscapes, which currently needs restoration and optimization. The thesis is substantiated that the ecological frame of the Altai Krai territory should be as close as possible to the structure of its natural landscapes, which will ensure the productivity of farmland. The most important elements of the ecological framework of forest-steppe and especially steppe landscapes are forest belts, for the creation of which it is necessary to use elements of a water-erosion network, tree species that form a zonal type of vegetation. Creating a system of protective forest plantations in combination with ponds and terrace embankments can increase crop yields up to 25-50 centners per hectare. Landscape planning can serve as a tool for creating an ecological framework for a territory.

From acceptance of the 1948 Plan of Field-Protective Afforestation to the present (2019), this article considers the new agroforestry paradigms protracted formation. Scientific achievements from the 1940s, introduced into practice, served as the basis for decisions on natures global transformation. Pilot facilities from the beginning of the 20th century (the Bogdinsky agroforestry stronghold, the Stone-steppe oasis) still serve as reference objects for agroforest reclamation of territories, with a scientific approach that allows them to function productively today. The plans main idea is to combat drought and desertification of steppe lands, erosion processes, and to prevent sand and dust storms. Creation of 5709 thousand hectares of protective forests, afforestation of 1106 thousand hectares of ravines, fixing and afforestation of sand on an area of 322 thousand hectares, and implementation of many planned activities during a short period locate this plan among other ambitious international projects. The authors draw attention to the time of creation and the volume of plantings of paramount importance, that is, state protective forest belts and protective forest plantations. Understanding the importance of agroforestry for modern agricultural landscapes led to formation of sustainable and durable agroforestry systems in subarid landscapes based on a combination of agricultural and landscape-ecological ideologies. Allegedly, considering terrain ecotopes, three-dimensional evaluation of the agrolandscape and a non-linear approach make it possible to create multifunctional, highly productive agroforestry systems in critical agriculture zones.

The Creation

Purpose. To characterize the methodological approaches that we develop in the formation of a system of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes and to show the results of their implementation on the example of the territory of some agricultural enterprises of the Kharkiv region. Methods. Cartographic, geoinformation analysis, calculation, statistical and mathematical. Results. Some results of the work of the collective on the issues of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes. Namely, verification of erosion models, studies of the functionality of shelter belts, the formation of an agroeconet (an extensive network of natural and quasi-natural landscapes) on agricultural land massifs, which ensures the maintenance of stable functioning of meso and macrolevel agrolandscapes, as well as the experience of using magnetic prospecting methods to verify the results of mathematical modeling of erosion processes. Conclusions. A number of methodological approaches to information support of the formation of sustainable agricultural landscapes in the natural and socio-economic conditions of Ukraine have been developed. They relate to the functioning of anti-erosion measures of permanent action, the processes of modern transformation of agro-landscapes, the ecological impact of erosion processes on the environment. The connection between the length of forest belts per unit of arable land and soil erosion is shown. A methodical approach has been developed to estimate the amount of soil washed away from arable land and to calculate the measures necessary to eliminate its harmful effects on the environment.

Protective forest plantations are an important part of forest-agricultural landscapes and one of the most effective long-term and relatively inexpensive measures to combat wind and water soil erosion. They have a positive effect on the microclimate of the surrounding areas and can significantly increase crop yields. Also, under certain conditions, they can become an important source of bioenergy feedstock. Goal. Development of theoretical bases and practical measures of the use of agroforestry reclamation plantations of Ukraine for energy purposes. Methods. In the course of the research it was envisaged to develop schemes of protective forest plantations on the basis of the analysis of the existing information, long-term production and scientific experience which, at full performance of ecological functions, can be used for obtaining bioenergy feedstock. Results. It is established that for the simultaneous use of protective forest plantations as a source of energy biomass it is necessary to include fast-growing woody plants (willow, poplar, acacia, maple, etc.) in rows or backstage, which are expected to be periodically cut for biomass. Such plants are then intensively restored by growth from stumps. The basis of such plantations for long-term and permanent performance of their protective functions should mainly consists of the rows of oak trees. Conclusions. Protective forest plantations, in addition to the positive impact on the microclimate of the environment and a significant increase in the productivity of agricultural land, can also play an important role as a source of bioenergy feedstock. Today, forest protection plantations are losing their functions for various reasons and need to be reconstructed. At the same time, along with the restoration of protective plantations, it will be possible to obtain about 54.6 million tons of wood for energy needs and form new protective plantations, which, along with improving the ecological environment, will create a reliable feedstock base for bioenergy. The schemes presented in the article can be applied at the stage of restoration and expansion of the field protection system to increase their energy role.

The article summarizes materials on the development and establishment of a scientific field - agroforestmeliorative soil science. Agroforestmelioration arose in the nineteenth century  based on it, with the active participation of V.V. Dokuchaev, agroforestmeliorative soil science developed as a forest soil science. The factors of soil formation under forest belts, the evolution and polymorphism of soils, the biogeocenotic horizon of the forest litter, soil regimes in the agroforestmelioration landscape, the influence of protective forest plantations on the soil, their role in reducing environmental pollution were studied, agroforestmeliorative zoning of Russia was carried out, and the forest suitability of soils was assessed. The ecological, energy and economic effect of CO2 sequestration from the reclamation effect of protective forest plantations  in Russia in the 20th century was calculated, which amounted to 256 trillion rubles. The cycle and balance of nitrogen and ash elements in the phytomass of field-protecting forest belts of the forest-steppe, steppe, dry-steppe and semi-desert zones of the Russian Federation was studied. The features of the type of cycle of elements are revealed. The average increase in humus in a meter layer of soil under protective forest plantations was 43.26 t/ha, gross nitrogen 2.181, phosphorus 0.704 and potassium 3.462 t/ha and at a distance of 4H from them, respectively, 8.22; 0.423; 0.271 and 2.243 t/ha. It was established that biologized crop rotation in the forest-reclaimed territory in the forest-steppe, steppe and dry-steppe natural zones increase soil yield by 1.9-17.0 points and crop productivity by 4355-9320 MJ/ha per year. For the first time in agroforestmeliorative soil science, materials are presented on changes in soil properties in the butt of tree species, soil reclamation of the phytogenic fields of trees and shrubs. The participation of agroforestmeliorative soil science in agroforestmeliorative agriculture, agroecology is shown. The tasks of agroforestmeliorative soil science for the coming period are proposed.

With an increase in the anthropogenic load on agricultural landscapes and global climate change, the role of not only the forests of Russia, but also artificially created, man-made forest stands, especially systems of protective stands, is growing. The system of forest belts of the Stone Steppe consists of forest strips of different ages, species composition and width. The oldest stands are 126 years old, the youngest are 28 years old. After the drought of 2010, the death of birch, poplar and partially ash began in many forest belts of the southeast of the Central Chernozem region. Forest strips of the Stone-Steppe system were not an exception. The death of birch and poplar occurred not only in old plantings, but also in middle-aged ones. It is necessary to know their renewable potential to restore the protective functions of forest strips. Old-age forest belts have suffered more from drought. Therefore the article is devoted to the study of the main reserve of renewable potential - the presence of reliable undergrowth and the conditions of its existence under the canopy of the parent forest stand of forest belts aged 62 to 120 years. The article touches upon the concept of a new direction in agroforestry: the mechanism of spatial expansion of protective forest belts on arable land due to the appearance of forest edges consisting of maple and the role of forest edges in the forest-forming process of man-made strip stands have been shown

An interesting aspect is the issue of acquiring natural features by artificially created tree plantations on the territory of the forest steppe zone of Ukraine. This paper analyzes the conditions of emergence and formation of new habitats rare plant species populations in different types of artificial trees and shrubs of the Forest Steppe of Ukraine. Complexes of natural and anthropogenic factors of necessary conditions creation for realization of this process are defined. The peculiarities of the negative impact of various economic measures on the reduction of the number of individuals of sozophyte plants and even the disappearance of some of their populations are reflected. The peculiarities of the negative impact of various economic measures on the reduction of the sozophyte plants individuals’ number and even the disappearance of some of their populations are reflected. To improve the protection of sozophytes in the forests of the forest steppe zone, it is advisable to review the implementation of certain methods of forest management measures. In particular, it is necessary to completely ban continuous felling in forests of natural origin and the allocation of biofields for natural reforestation. To improve the condition of forest coenoses of protective plantations, including field protective forest strips, it is necessary to conduct a series of experiments with the subsequent development of technology for their coenotic correction in order to increase the general ecological, including phytososological, significance. The implementation of a set of phytomeliorative measures in the creation of protective forest plantations to some extent will help prevent possible climate change, local disasters and will have a positive impact on the processes of crop formation. The creation of sustainable forest plantations will allow the application of environmental protection measures using the regulatory and protective functions of forest ecosystems. Compliance with all these conditions will contribute to the manifestation of various environmental measures for the development and conservation of biological diversity.

Protective Forest

Field protective forest plantings of the steppe zone of Ukraine are one of the most important links in the system of protective forest plantations on arable lands. The presence of well-functioning field protective forest belts is a fundamental condition for efficient agricultural production in the steppe regions of Ukraine. The paper presents the facts about the expediency of creating protective forest belts as an important measure to support the agricultural potential of the steppe zone of Ukraine. The current state of forest belts is analyzed and historical literature information on the creation and prospects of development of protective afforestation in the steppe of Ukraine is presented. The legal aspect of the mode of operation of field protective plantations is highlighted. Given the low forest cover of a large area of Ukraine, the difficult and ambiguous situation of afforestation of forest-deficient areas of the country, the creation of new and preservation of existing protective forest belts in the steppe zone of Ukraine is an extremely important task today. The problem of ensuring the effective functioning of field protective plantations in the conditions of ecological inconsistency of forest vegetation conditions for the existence of woody vegetation in Dnipropetrovsk region, in the zone of weeds-fescue-feathergrass steppes is acute. Against the background of a number of well-known indisputable facts about the positive impact of forest belts on the soil and climatic properties of steppe landscapes, the condition of most existing protective plantations today is unsatisfactory, and some of them – critical. Almost everywhere in Ukraine, in conditions of high plowed lands and the absence of forest strips or their neglected condition, there is a rapid destruction of the upper fertile layer of soil. This leads to soil degradation, reduced yields and causes great economic damage to the country. Mass uncontrolled logging, destruction of protective forest belts, their irrational use and lack of proper care are a critical problem of national scale and may soon turn into an environmental disaster. An acute modern problem in the existence and functioning of forest belts is the solution of the legal regime of field protective tree strips and the introduction of appropriate legislative state regulation. An equally painful problem for field protection strips today is the lack of reliable information about their real condition. Therefore, obtaining a general idea of the current state and dynamics of field protection strips is possible only if they conduct a detailed comprehensive study and conduct a thorough inventory. For successful planning and implementation of measures to increase the forest cover of forest-deficient regions with difficult forest vegetation conditions and create an effective system of protective forest belts should take into account the history and many years of experience in creating forest plantations in the steppe of Ukraine.

Biological Potential

In Ukraine 57.5 % of agricultural land is subjected to erosion with 10–24 million tons of humus, 0.3–0.96 million tons of nitrogen, 0.7–0.9 million tons of phosphorus and 6–12 million tons of potassium lost annually. Degradation processes are also common on chernozems, which cover about 60 % of the Ukrainian territory. The aim of the research is to defi ne the most eff ective soil conservation practices and legislative decisions aimed to conservation/recovering the Ukrainian chernozem fertility. The experimental data of the agrochemical certifi cation of Ukrainian lands, data from scientifi c papers, stock and instructional materials as well as our own fi eld and laboratory studies were used. It has been established that the long-term use of deep subsurface tillage on typical chernozem increases, compared with plowing, the content of 10–0.25 mm of air-dry and water-resistant aggregates, the bulk density, soil water storages, water infi ltration rates, the content of mobile phosphorus and exchangeable potassium, pHH2O, CaCO3 stocks, the contents of humic and fulvic acids, molecular weights of humic acids – by 5.5 and 3.06 %; 0.05 g/cm3; 25.5 mm; 22.6 mm/h; 0.1 and 3 mg/100 g of soil; 0.03 pHH2O; 18 t/ha, 0.02 and 0.04 %, 91195 kDa, respectively. Fertilizers may contribute to the crop yields increase from by 60% in the Polissya, by 40 % – in the Forest Steppe, by 15 % – in the Wet Steppe, by 10 % – in the Dry Steppe and by 40 % – in the Irrigated Steppe areas. In soil-conservation rotations, the crop placement and alternation are advisable to combine with strips or hills sowing, taking into account the local relief features; soil alkalinization, applying anti-erosion structures. Ukrainian agriculture will receive additional 10–12 million tons of forage units or 20–22 % from all fodder in a fi eld agriculture under increasing 8–10 % of arable lands for intercrops. It is advisable to mulch the eroded chernozems of Ukraine depending on their texture composition: 1.3 t/ha of mulch for sandy and loamy soils, 1.9 t/ha – for sandy and 1.1 t/ha – for loamy soils. The implementation of soil conservation agriculture can minimize some soil degradation processes and improve eff ective soil properties required to realize the biological potential of cultivated plants.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

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.
