The article presents the current state assessment and suggests the methods for additional moisture supply of soils under stable tree plantations of Siberian elm (Ulmus pumila L.) on brown soils of semi-desert. The research area belongs to the arid zone. This is a treeless zone of dry steppe and semi-desert, where about 1,000 ha of plantations with a predominance of elm of different species have been planted since 1949–1953: shade clumps, pasture protection strips, massifs, separated forest stands. The soils are brown desert-steppe alkaline sandy loam and light clay-loam in combination with solonetz (10 %). Siberian elm stands form plantations of different ages and for different purposes. The research is based on biomonitoring materials and field experiments using standard forest inventory techniques. Test sites of a rectangular shape with an area of 0.4 ha were laid out in order to study the Siberian elm stands. We described in detail the location of the test sites, the soil composition thereon, and gave a comprehensive assessment of the growth and durability of the plantations. It is shown that the stand state is determined by 2 sets of factors: zonal-edaphic and pastoraleconomic. Viable stands of Siberian elm at the age of 57–64 have been preserved on sandy loam and dark-colored soils located in micro- and inter-hill depressions. The dynamics of soil moisture under plantations is largely independent of the tree location method. Satisfactory indicators of growth and durability of plantations depend on the level of availability of soil moisture and the degree of its salinity. The moisture supply of soils under elm plantations can be increased by using melt water runoff in hollows and micro-depressions and increasing the growing space of a tree to 25 m2. Formed elm plantations respond positively to the presence of resting animals. The “alliance” relationship between the stand and livestock does not arise immediately, but rather from a certain age of the stand and the moment it forms a certain structure of the tree layer, which should be provided by forest cultivation and silvicultural measures in conjunction with the regulation of pasture load. There is a positive effect of resting animals at the appropriate load on the growth, state and durability of the Siberian elm stands.

The article presents the results of an assessment of the chemical composition and nutritional value of the most common vegetation of various life forms (trees, semi-shrubs, perennial grasses) in the forest pastures of the semi-desert zone of the Northwestern Caspian Sea. The research was carried out on forested pasture areas of the Neftekumsky district of the Stavropol Territory. The basis of the research was the laboratory-field method. The twig-leaf and herbaceous phytomass of forest pastures, in accordance with its chemical indicators of organic matter content, meets zootechnical requirements. The maximum protein content is observed in spring in the woody greenery of Ulmus pumila (at the level of 18.19%) and decreases in autumn (17.4%). In addition, it was found that the twig-leaf mass of Ulmus pumila has a relatively high feed value (0.68 f.u., 8.5 Mj, digestible protein 62.67 g/kg) than herbaceous species and is a large reserve in forest pastures during drought or absence of herbaceous vegetation before the establishment of snow cover. As a result of the research, it was also found that during the dry period (summer) in the grass-grass and grass-grass phytocenoses, there is a low protein content (less than 10%) and a high fiber content (34.0–35.13%). The nutritional value of plants in general on man–made forest pastures is 0.25–0.68 fodder units, while 1 kg of feed contains 31.0–78.48 g of digestible protein. The fat content in the analyzed plants in the territory under consideration is small (1.10–4.23%), and the content of nitrogen-free extractives is quite high (30.44–65.2%) regardless of the season of the year. According to the content of macronutrients, a deficiency of phosphorus (P) was detected according to the norms. Accordingly, with constant grazing of animals in these areas, it is necessary to additionally include feed additives containing this element in the diet for the prevention of deficiency and diseases.

Haphazard use of pastures has become one of the factors of disturbance of their natural vegetation. Therefore, forest reclamation works were carried out and significant areas of strip plantations of shrubs were created in the Caspian Sea region in the mid-20th century. In the arid zone of Russia, one of the most important tasks in the field of scientific provision of protective afforestation is the improvement of methods and techniques of arrangement, increasing longevity and environmental, agricultural, and utilitarian efficiency of plantations. This study aims to determine the long-term impact of afforestation on the functioning of pasture ecosystems. The influence of tree and shrub layer on biodiversity and productivity of vegetation cover of pastures was also studied. The research objects are plantations growing on the reclaimed pastures. The research is based on the materials of biomonitoring and field experiments using standard methods of forest inventory and geobotanical survey. Rectangular-shaped test plots of 0.25–0.30 ha were laid out for the study of forest plots. Test plots were used for a detailed description of the location, soil composition, time, method, and technology of plantation development, as well as a comprehensive assessment of the growth and longevity of tree and shrub crops. Data from key plots were used to study the successional processes of vegetation cover. The research results have shown that deep plowing preparation of soil to obtain high results in rooting, preservation, and growth of shrub species has an advantage over other soil preparation technologies in the semi-desert zone. It was found that the shrub layer up to 45 years old retains its productive and generative abilities. Pasture protection belts from Haloxylon aphyllum and reclamation and fodder plantations from Krascheninnikovia ceratoides and Calligonum aphyllum have a high cenosis potential and stability. In this case study, in semi-arid regions, afforestation with shrubs is the best way to improve and restore pastures. For citation: Rybashlykova L.P., Lepesko V.V.
