Changes in the properties of soils under phytomelioration
In the article problems of interaction of soil and plants are considered. Studies have been carried out on chemical and biological properties of soils at cultivation of astilbe (Astilbe japonica), hosta (Hosta crispula f. Maekawa), ochitnik (Hylotelephium triphyllum), aster (Aster novo-belgii). The research found various biochemical compounds produced by these types. These properties are recommended to take into consideration when landscape gardening and design formation.
