The article represents the results of the experiments on biological activity of humits of different sorts. The object of research was humic preparation called Vermistar, which was obtained by vermiculturing, on the basis of brown coal. Humics are group of high-molecular substances which have high physiological activity. Humic substances stimulate all biochemical processes on all the stages of plant growth. They change the permeability of the cell membranes, increase activity of ferments, amount of chlorophyll and productivity of photosynthesis. Also humits are not toxic; they don’t have carcinogen and mutagenic effects, so we have a chance of getting environmentally friendly products. The experiment results show high biological activity of humic preparations. Usage of humic stimulates germination, the accumulation of vegetative mass, weight gain. The frequency of shoot has been increased by 17-32%. Height of shoots, roots and vegetative mass has also been increased
