The article presents research materials on the impact of shelterbelts on the growth and development of spring barley. It has been established that the reserves of productive moisture on the inter-strip cell are distributed unevenly and vary depending on the distance from the forest belt. The greatest spring moisture reserve (in the conditions of agroforestry) accumulates in the zone from 5H to 15N from forest shelter belts. The yield of spring barley in the inter-strip space is formed depending on the distance to the forest belt. The distance from the forest belt and its influence on the phases of plant development has been critically evaluated based on mathematical modeling and empirical data. Data on the average daily moisture consumption of barley plants by development phases have been processed to clarify the factors affecting the formation of the crop. Functional relationships have been obtained using STATICTIKA computer program. High correlation between the distance from the forest belt and the phases of barley has been found: tube forming (R = -0.94), booting stage (R = -0.93), blooming period (R = -0.93). The forecast for barley development in the phases of grain filling and ripening is slightly lower and amounted to R = -0.89. The relationship between the coefficient of water consumption and the distance from the forest belt has not been identified. The analysis has showed the influence of the barley water consumption coefficient depending on the distance to the forest belts on the vegetation phases of this crop. The results of the study indicate the important role of forest belts

xModern forest shelter belts do not fully protect arable land and most often have a different life state. In theseconditions, the preservation of forest belts, their performance of protective functions in the system of agroforestry andother complex measures remains an urgent task. The studies were carried out in a field-protective forest belt located in thevicinity of the Oktyabrsky village of the Krasnoturansky district of the Krasnoyarsk Territory, where a temporary test plotwas laid using generally accepted methods. The aim of the research was to study the current state of this forest belt by identifying the sanitary state and preservation of the stand and growth rates of Scots pine. Analysis of the current state of thestand showed that the average category of the state of trees is 1.3 points. The stand safety is 44.9%. Pine trees at the age of 28after planting have reached an average height of 11.6 m with an average diameter of 19.1 cm. The forest belt has an optimalopenwork-blown design and is capable of self-renewal naturally. To prevent further degradation of arable leached chernozems in treeless areas of the steppe zone of the Krasnoyarsk Territory, it is advisable to create pine forest shelter belts.

The authors in this article reviewed and analyzed works that consider the features of the distribution of snow cover under the influence of field protection belts. The aim of the work is to study the influence of forest shelter belts on snow accumulation depending on the climatic conditions of the city of Lugansk. The research was carried out in the city of Lugansk, on the basis of the educational and production agricultural complex "Kolos" of the Lugansk national agrarian university (UNPAK LNAU "Kolos"). The object of research is forest shelter belts of openwork-blown structure. A VS-43 snow meter was used to measure the mass of the snow cover. The depth of the snow cover was measured with a portable snow gauge M-104. The density of the snow mass and the water reserve in the sample were calculated mathematically. The authors found that the average height of snow cover on the windward side of the shelter belt is from 6.00 to 10.25 cm and the sample weight is from 33.50 to 68.75 grams. The data obtained indicate that more snow accumulates on the leeward side of the field protection strip than on the windward side. The minimum height of the snow cover on the windward side is 3 cm, and the maximum is 9 cm. Whereas the minimum height of the snow cover on the leeward side is 10 cm, and the maximum is 17 cm. The authors emphasize that as a result falling out of common ash from the strip, there is a tendency of transformation of the strip from openwork-blown to blown, when the height of the snow cover rarely exceeds 1 m and snow is blown out from under the canopy of the forest belt.

Features of fertility dynamics indicators of typical chernozem determining agroecological state soil under these ecosystems are established under differentage forest shelter belts located on various slope exposures on the territory of the experimental field of All-Russia Research Institute of Arable Farming and Soil Erosion Control (Kursk Region, Medvensky District). The study period was 16 years, the age of the forest shelter belts is 20 and 36 years. It is found out that longterm growth of woody plants on typical chernozem results in an increase in its fertility. Moreover, there is the variation of soil properties differs in intensity in forest shelter belts that differ by location in the relief. In all forest shelter belts, regardless of the location in the relief, there is an improvement in the agrophysical state of the soil, an increase in the content of humus, mobile humus substances, mobile potassium, and phosphorus. However, the intensity of changes varies depending on the exposure of the forest shelter belt on the slope. So, on the southern slope there was a maximum increase in the content of humus, mobile phosphorus, exchange bases, and water-flow aggregates. In the soil of the watershed plateau, there was a significant increase in the content of humus, the degree of humification, mobile humus substances, but their qualitative composition and content of agronomically valuable aggregates have not changed. On the northern slope, there was the maximum increase in the criterion of water resistance of soil. With increasing age of forest belts, the aboveground herbaceous phytomass increases with an increase in its share of green biomass and the amount of accumulated litter decreases. The highest phytomass productivity was in the offshore forest belt of the southern slope. Studies have shown that long-term growth of forest shelter belts improves the agroecological state of the soil, regardless of their position in the terrain, which contributes to an increase in the ecological potential of the agricultural landscape. A correct understanding of the direction of changes in the agroecological state of the soil will optimize the structure and functioning of the agricultural landscape.

Today forestry in Russia is going through one of the most difficult periods in its history, which has resulted in decades of extensive wasteful land use. So, change of climate can bring desertification of some territories and various forms of degradation (desertification) cover about 60 percent of the land in the Rostov region, and the rest is potentially dangerous in this regard. The reasons are anthropogenic impact, drought, erosion, deflation. Despite the fact that in recent years Russia has been developing forestry legislation and has taken a course towards the development of sustainable growth and "green" one, the regions are taking measures aimed at protecting lands from degradation and preserving soil fertility, soil-destructive processes and desertification are increasing many times over. An inventory of forest resources in Russia was carried out in 2019 and it showed that the forest cover in Russia tends to decrease, and on the territory of the Rostov region, forest inventory was carried out in 2006, only 40% of all forests were taken into account - about 240 thousand hectares of protective forest plantations, from of them 125.8 thousand hectares are shelter belts. It’s imperative to enact urgent measures for reforestation and landscaping of territories and annually reconstruct forest belts and create new ones to improve environmental conditions in regions with low forest cover, otherwise in 10-15 years their mass natural death may occur.

Coccinellidae perform the function of biological control of pests in nature, they eat aphids and other insects, which is important in organic agriculture. The aim of the work was to establish the distribution and species composition of the family Coccinellidae in the organic agro-landscape. The research was conducted at the Skvyra research station of organic production (Kyiv region, Ukraine). Insects were collected by entomological mowing with a net in four stages of plant development. The organic agro-landscape included crops of buckwheat, oats, soybeans and winter wheat. Data from neighbor conventional soybean and winter wheat ecosystems were used for comparison. The agroecosystems of these crops, which included felds, ecotones ”feld – feld protective forest shelter belt”, feld protective forest shelter belts, were studied. The study identifed 10 species of the family Coccinellidae, the number of species ranged from 1 to 89/100 waves, the largest in the ecosystem of organic winter wheat. H. axiridis belonged to the recedents and was found in fve agroecosystems in the amount of 1-7 individuals / 100 waves. The most common species were C. septempunctata, T. sedecimpunctata and larvae of Coccinellidae, which were eudominant in the organic agro-landscape. Species Vibidia sp. was found only in organic agroecosystems of buckwheat and oats. The variety of ladybugs in organic winter wheat was higher than in conventional. Organic soybeans, in contrast, had less variety of Coccinellidae than conventional soybeans, as confrmed by cluster analysis. Species richness in crop ecosystems ranged from 3 to 8 in different study periods. High correlations of insect numbers were found between felds, ecotones and forest shelter belts, as well as between neighbor ecotones and neighbor forest belts, which indicates the migration of insects between these areas. Thus, the diversity and prevalence of Coccinellidae in the organic agro-landscape, compared to the traditional one, has been established. Key words: ladybugs, organic farming, agrolandscape, agroecosystem, crops, species.

The article analyzes the experience of the impact of the system of forest belts and mineral fertilizers on the yield of spring wheat, including on irrigated lands. Vegetation irrigation is designed to maintain the humidity of the active soil layer from germination to maturation at the lower level of the optimum-70-75%, and in the phases of tubulation-earing - flowering - 75-80% NV. However, due to the large differences in zones and microzones of soil and climate conditions and due to the weather conditions of individual years, wheat irrigation regimes require a clear differentiation. In the Volga region in the dry autumn rainfalls give the norm of 800-1000 m3/ha, and in saline soils – 1000-1300 and 3-4 vegetation irrigation at tillering, phases of booting, earing and grain formation the norm 600-650 m3/ha. the impact of the system of forest belts, mineral fertilizers on the yield of spring wheat is closely tied to the formation of microclimate at different distances from forest edges.
