"The objectives of the research respond to the topical problems of the presence and near future related to the protection of soils, maintenance of their production and ecological functions and prevention of soil contamination and degradation. The factors of soil fertility, organic matter transformations and biological processes affecting immobilization and release of plant nutrients are studied. Due to the character of soil processes, long-term field experiments in different soil and climatec condition s are the basic experimental onject for these studies. Continuous anthropogenic load on aoils (industrial immissions, soil contamination and intensive agricultural technologies) can caus a harm to soil qualiyt, which can be irreversible. Microbiological methods are therefore selected and tested, which could be a useful tool to assess environmental hazards. The possibilities to increase the effectivity of symbiotic N fixation and mineral phosphate solubilization by rhizobia are investigated."@en . . . . "11"^^ . . . "0"^^ . . "0"^^ . "11"^^ .
