The results of the study of protective forest plantations state in the Eastern Kama region of the Republic of Tatarstan are presented. The assessment of the study area landscape, the soil conditions for the formation of protective forests is given. Under the canopy of forest phytocoenoses, brown-brown forest, gray forest soils and rendzins are identified. Pine, spruce, birch, and poplar protective plantations, pure and mixed in composition, were studied. On the trial plots the taxation indicators of stands are determined. The peculiarities of the distribution of trees along the thickness steps and categories of the state are revealed. In pine biogeocenoses there are obviously more trees without signs of weakening: the content of healthy trees is 70.5-87.4%. Less stable are pine plantations created on stony soils of a steep slope. A higher proportion of healthy trees are allocated pine phytocenoses formed on loamy brown soils. Protective plantations of Almetyevsky municipal district, created from European spruce on soils with a developed profile, are distinguished by a high proportion of trees without signs of weakening. In the composition of deciduous plantations, a high percentage of trees without signs of weakening are inherent in the mulberry, which grows on brown-brown forest heavy loamy soil. There are no strongly weakened and drying trees. Birch grouse, formed on rendzine leached heavy loam on stony calcareous rocks, is less stable: the proportion of weakened trees increases to 20.1%.

Protective Forest

4 types of protective forest stands have been studied: moor, slope, soil, roadside on the degraded lands of the Eastern Kama region of the Republic of Tatarstan. Protective forests of artificial origin, formed of pine, larch, spruce, poplar, birch, maple, elm. The following types of forest biogeocenosis are distinguished: pine grass, mixed birch forest, spruce grass, poplar motley grass. Protective forest phytocenoses have a significant variety of plants, 14 species of woody, 6 species of shrubby and semi-shrub species, 39 species of herbaceous plants have been identified. In the composition of phytocoenoses, pine plantations predominate, the share of deciduous crops is low - 7-12%. Protective stands of slope landscapes of the forest-steppe of the Kama region have 1st class of age for coniferous species and I-II classes of age for hardwoods, are characterized by high productivity: they grow according to II-I class of bonitet. Pine stands are highly productive, single-stage, clean in composition. The largest reserve of wood is the mixed pine forest. The average diameter of plantations varies from 7.3 to 10.9 cm, the average height varies from 5.7 to 8.8 m. Type of forest conditions D2 (fresh oak forest). Deciduous protective plantations of poplar hybrids-38 and birch bark have a high survival rate and productivity (class I bonitet). The average diameter of plantations varies from 5.3 to 6.8 cm, the average height varies from 6.0 to 7.0 m. Plantations grow: on fertile gray forest soils developed on deluvial and loesslike loams; brown-brown forest soils developed on Permian rocks; rendzinas typical and leached, developed on limestones. The soils have a loose composition of the upper horizons, which transform into dense horizons in the lower horizons; medium loamy, heavy loam and light-clay granulometric composition, good water-resistant structure, high content of agronomically valuable aggregates of 0.25-10 mm in size, saturated with organic matter, and possess high forest growth properties.

Forest Shelter Belts

Forest shelter belts are one of the effective approaches in the fight against wind erosion, improving the microclimate of fields, protecting roads and reservoirs. The problem of assessing forest plantations and prospects for their creation is relevant for many countries of the world, due to the problem of desertification, water and wind erosion, as well as the global food crisis. The carried out analysis of scientific literature has shown that the existing assessments of forest shelter belts with insufficient degree are being taken into account the modern methods of remote sensing.Therefore, the problem of assessing forest shelterbelts from satellite imagery is relevant.The main part and research results. During the summer period of 2019, in the territory of the protective forest plantations of Fergana Valley of the Republic of Uzbekistan there were laid 170 testing plots. Then 20 test sites, which were used as reference for thematic mapping, there were laid with the collection of additional information: location coordinates and bookmark location.The purpose of the study is to assess the area of forest shelter belts zones of the Republic of Uzbekistan using remote sensing.The object of the study is forest shelter belts of Fergana Valley of the Republic of Uzbekistan.

Abstract The article presents the results of a cameral inventory of protective forest plantations of a linear type for any purpose for the steppe agricultural territories of the Crimean Peninsula in 2009 and 2019. As a result of the work, more than 20 thousand objects were identified, a geodatabase was compiled with a set of attributive information for each of the identified objects, indicating the length and quality characteristics of each object. An overview of the data obtained is presented for each of the diagrams, as well as a comparative analysis of the quantitative and qualitative characteristics of the identified objects for 2009 and 2019. It was revealed that from 2009 to 2019, 386 objects of the linear type corresponding to the parameters of protective forest plantations in agricultural areas, with a total length of 3.9 thousand were completely destroyed. That is, well-read forest stripes are present in the images for 2009, in the images of 2019 they are already missing.

Reclamation of land on community land funds and the hydrographic network contributes to the most effective means of protecting the soil from water erosion. However, the condition, growth, and productivity of the protective forest stands themselves depend on the species composition. Many years of studies have clearly shown that not all tree species and shrubs can successfully grow on washed soils. Extensive scientific material provides a description of the growth and current status of the studied species, a detailed taxation description of the forest plantations. Of particular value are those species that can grow on eroded lands and protect the soil from erosion.

Agriculture is a traditional branch for the Republic of Bulgaria. The favourable agriclimatic and soil conditions further the growth of 145 agricultural crops and the production of various products, many of which have leading positions in the international market. The aim of this paper is to examine the nature and specific features of the reform of the land relationships in the Republic of Bulgaria during the period of transition towards market economy. The development of land relationships in this country reflects the economic interests of its society, which show their specific nature in the relationships between the owners and the leaseholders of the plots. It is typical for this country that during the collectivisation period, which took place in the middle of the last century, the land, being the basic production factor in the agricultural branch, was public property, the private character of which was never abolished. During the transition period, a process for restoring the land ‘within its real borders’ was started. This led to delay in the reform and a significant fragmentation of the land. The completed agricultural reform contributes to the recovery and precipitation in the process of developing of the land relationships in the country. A sign of this is the formation of land market. In the year 2001, 28 878.1 ha changed their owners, and another 280 000 ha were leased. The aim is, through active laws, to achieve synchrony of the social interests with the interests of the owners and leaseholders and to create conditions for optimisation of the production process in agriculture. A favourable economic environment will contribute to increasing the efficiency of the agricultural branch in the Republic of Bulgaria and to the formation of the land relationships, which will facilitate the process.

Soil acidity and aluminum toxicity are considered most damaging soil conditions affecting the growth of most crops. This paper reviews the results of tests of pH, exchangeable acidity and mobile aluminum (Al) concentration in profiles of pseudogley soils from Cacak-Kraljevo basin. For that purpose, 102 soil pits were dug in 2009 in several sites around Cacak- Kraljevo basin. The tests encompassed 54 field, 28 meadow, and 20 forest soil samples. Samples of soil in the disturbed state were taken from the Ah and Eg horizons (102 samples), from the B1tg horizon in 39 field, 24 meadow and 15 forest pits (a total of 78 samples) and from the B2tg horizon in 14 field, 11 meadow, and 4 forest pits (a total of 29 samples). Mean pH values (1M KCl) of the tested soil profiles were 4.28, 3.90 and 3.80 for the Ah, Eg and B1tg horizons, respectively. Soil pH of forest samples was lower than those in meadow and arable land samples (mean values of 4.06, 3.97 and 3.85 for arable land, meadow and forest samples, respectively). Soil acidification was especially intensive in deep horizons, as 27% (Ah), 77% (Eg) and 87% (B1tg) soil samples had the pH value below 4.0. Mean values of total exchangeable acidity (TEA) were 1.55, 2.33 and 3.40 meq 100 g-1 for the Ah, Eg and B1tg horizons, respectively. The TEA values in forest soils were considerably higher (3.39 meq 100 g-1) than those in arable soils and meadow soils (1.96 and 1.93, respectively). Mean mobile Al contents of tested soil samples were 11.02, 19.58 and 28.33 mg Al 100 g-1 for the Ah, Eg and B1tg horizons, respectively. According to the pH and TEA values, mobile Al was considerably higher in the forest soils (the mean value of 26.08 mg Al 100 g-1) than in the arable soils and meadow soils (the mean values of 16.85 and 16.00 mg Al 100 g-1, respectively). The Eg and B1tg horizons of the forest soil had especially high mobile Al contents (the mean values of 28.50 and 32.95 mg Al 100 g-1, respectively). High levels of mobile Al were especially frequent in the forest soils, with 35% (Ah), 85.0% (Eg) and 93.3% (B1tg) of the tested samples ranging above 10 mg Al 100 g-1.

The Impact

Conducting soil studies are relevant in determining the subordination of forest types and biodiversity of vegetation to soil taxa, in determining the dependence of basic forest stand productivity from soil conditions, in creating a land registry and economic assessment of forest land, in studying the soil evolution of forest plantations under the impact of anthropogenic influences. Soil is the most important environmental factor in shaping the productivity and biodiversity of forest phytocenosis. The study of forest soils is also important in terms of basic research of their genesis, evolution. The article presents the results of research of soil conditions of vegetation growth of forest ecosystems of northern regions of Volga of the Republic of Tatarstan. The main types of forest soils are characterized in the paper. The studied forest formations grow on various soils on genesis and forest vegetation properties: sod-podzol, gray forest, brown forest, brown forest sandy, alluvial meadow, rendziny soil. The granulometric structure of soils varies from sandy to the clay. The well structured soils are formed on loamy layers under forest phytocenosis canopy. Pine and spruce ecosystems have a medi-decomposed litter of moder and multi-moder types; linden, oak, birch and aspen biogeocoenoses have strong-decomposed litter of multi type, that characterizes the intense biological cycle of substances in forest ecosystems. The wide range of place conditions of territories causes the biological diversity of forest vegetation at the level of species and ecosystems.
