Abstract

Some features of the influence of Robinia pseudoacacia L. (black locust) on soils in arid conditions The modern scientific sources concerning the peculiarities of the influence of Robinia pseudoacacia L. on soils under arid conditions have been analyzed. As a result of the performed analysis, it turned out that the largest number of scientific sources is devoted to the highlighting of the specifics of the influence of plantings on the content of organic substances, nitrogen, phosphorus, potassium, soil moisture, as well as erosion processes and the process of recultivation of disturbed lands. The main influence of Robinia pseudoacacia L. on the organic matter content is manifested in increasing the soil organic carbon content in the upper layers of soils, as well as in its increase in soil content, preferably up to a depth of 50 cm, compared with some other trees and herbaceous plants. Nitrogen is the main biophilic chemical element that is actively accumulated by black locust plantings. At the same time, the positive effect of Robinia pseudoacacia L. on the accumulation of phosphorus and potassium in soils was found, which positively affects the increase of soil fertility under plantings. An analysis of literary sources has revealed that there are results of researches that confirm the use of black locust from moisture from both surface and deep layers of soils. Plantings of Robinia pseudoacacia L. are actively used in arid conditions to overcome the manifestations of erosion processes. In this case, an additional mechanism of anti-erosion stability of the plantation, some authors consider the formation of forest litter in black locust forest stands. Robinia pseudoacacia L. due to its adaptations is successfully used in the recultivation of disturbed lands, actively improving their properties and increasing their fertility. It should be noted, however, that most European countries regard Robinia pseudoacacia L. as an invasive species whose invasion negatively affects indigenous plant communities. At the same time, the countries, a significant part of which falls on arid lands, actively use black locust for afforestation and improvement of the state of their soils.

“…Li et al (2017) відзначають, що створення робінієвих насаджень на ґрунтах, які до цього втратили лісовий покрив, забезпечує краще збільшення вмісту та зберігання ґрунтового органічного вуглецю порівняно з насадженнями Caragana korshinskii, а також угрупованнями Stipa bungeana + Artemisia gmelinii. При цьому автори зазначають, що робінія краще забезпечує збільшення органічної речовини в лісових ґрунтах порівняно з піщаними ґрунтами (Gorban & Huslystyi, 2018).…”
