The research was made in the 2006 - 2008 period on the production of tobacco seedlings in field conditions. The tested biological products are: Biohumus solid and liquid forms; Kompovet; microbial products - BioLife and B5A. It is established that the products - Biohumus solid form and Kompovet can successfully replace the mulching cover of mature in the production of tobacco seedlings made by the classic technology. The products - Biohumus liquid form, BioLife and B5A can be used for feeding the tobacco seedlings as an alternative of feeding of the tobacco plants with NH4NO3. The tested products raise the population density the autochthonous microorganisms in the soil and have a positive effect on the soils biological characteristics.
