The specificity of allelopathic activity concerning different species of higher plants is revealed. In particular, allelopathic chlorella secretions stimulated seed germination and the development of wheat and tomato sprouts but inhibited the growth of amaranth. The resulting dependence involves the use of chlorella culture fluid not only to increase crop productivity but also to control certain types of weeds in crops. It is proved that the deficiency of mineral nutrients in the soil enhances the competitive relationship between higher plants and microalgae. Evidence of indirect participation of chlorella in CO2 runoff processes due to intensification of biosynthesis of photosynthetic pigments and stimulation of plant growth processes has been obtained. This is confirmed by data on an increase of 61-70% in the number of ammonifiers and a decrease of 42.9-46.6% of microorganisms immobilizers of mineral nitrogen. Analysis of the species composition of algae in natural and artificial beech plantations showed the complete absence of cyanoprokaryotes, a significant difference in species diversity. The area of exposition of NBS beeches differed both by a higher diversity of species and by a rather specific species composition of algae, completely different from the localities of beech virgin forests (only 1 common species of algae).
