Methods have been investigated for increasing soil fertility, using new biofertilisers, created on the basis of two sewage sludge (SS) biological treatment plants with the participation of an active strain of phosphatemobilising microorganisms. To create composts (biofertilisers), sewage sludge (after 3 years of storage on the sludge areas) was used with fillers (winter wheat straw and sunflower seed husks) in a ratio of 5 kg of SS: 5 kg of the organic filler and a suspension of microbacterium barkeri at the rate of 10% of the total mass of compost. The obtained results of determination of the biological activity of the soil according to the decomposition degree of the flax fabric showed an increase in the microbiological activity when new biofertilisers were introduced. In the rhizosphere soil the amount of microorganisms of various ecological and trophic groups was studied. The obtained results indicate a positive effect of the use of new biofertilisers contributing to an increase in the biological activity of the soil.
