FIELD: biotechnology. SUBSTANCE: invention proposes a method of immobilization of physiologically active compounds of trace elements comprising the composition of a mixture of these compounds with addition of immobilizing agent and the following treatment of mixture and granulation of the ready product. Method is based on the use phosphates and their mixtures with molybdates, carbonates, sulfates and nitrates including trace elements as a immobilizing agent, the following mixture melting, preparing vitreous active micrononhomogeneous amorphous mass and its granulation. EFFECT: improved method of immobilization. 2 tbl, 2 ex
