Forest Shelter Belts

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.

The paper focuses on the insect community as a "link" between ecosystem producers, secondary consumers and decomposers and the mobile and informative indicator of structure, biological stability and productivity. Consortium and other subsystems of agricultural ecosystems are mainly destroyed annually as a result of technological measures - chemical, mechanical, biological. External ecological factors, including the structure of the agrolandscape, in particular field protective forest shelter belts and ecotones between them, also have a certain influence. The research was conducted in organic agrolandscape (Kyiv region, Ukraine), comparing it with the conventional one. Insects were collected in winter wheat fields, ecotones and adjacent forest shelterbelts. The number of orders, families and individuals is greater under organic farming. The highest number of families and individuals was recorded in the forest shelterbelts adjacent to the organic landscape (26.3 and 111.7, respectively). The number of individuals in organic winter wheat fields was twice as large as in conventional fields and amounted to 85.3 individuals on average; the number of families was by 1.8 times larger. Biodiversity indices (Shannon, Menhinick, Margalef, Berger-Parker, and Pielou) confirm the greater diversity of insects in the organic fields of winter wheat. The Sørensen similarity coefficient was higher in the organic fields and forest shelterbelts near the conventional fields (Cs=0.7), which is explained by the largest number of phytophages in these ecosystems. The share of predators and parasites that control pests in the agricultural system was highest in organic ecotones and forest shelterbelts - 26.21% and 33.12% (against 10.24 and 18.16% in conventional, respectively).

Forest Shelter Belts

The influence of recreation of varying intensity on the health condition and structure of forest shelter belts formed by common oak (Quercus robur L.) and green ash (Fraxinus lanceolata Borkh.) is estimated. The long-term impact of recreational pressure on shelterbelts that were identical at the time of creation was evaluated. It was found that the long recreational influence of different intensity leads to a significant decrease in the stocking of the tree stand (by 27.5%), changes in the stand structure, deterioration of health condition (in the S-2 section, the health condition index was І.7 and in the S-1 section, ІІ.3) and a decrease in the average diameter of the trees (by 20.5 %). In addition, such an effect led to a significant reduction in the density, both for advance growth (by 73.5 %) and undergrowth (71.3 %), which ultimately affected the change in the openness of the vertical profile of the shelterbelt. Frequently, uncontrolled burning of refuse and dry grass by recreators provoked the emergence of surface fires and additional weakening of the trees in the stand (the health state of damaged trees fluctuated within the 3-4 category of health condition) as well as partial destruction of the advance growth and undergrowth. Cenomorphic analysis of forest phytocoenoses by Belgard revealed the predominance of ruderants. Sylvants (typical species for the forest) and Pratants (steppe species) are represented by three species and have occurred seldomly.

Forest Shelter Belts

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.
