Abstract

We have studied the morphological and physicochemical characteristics of the soils of the Baer knolls in the Astrakhan region. Cyanobacterial communities were identified from the soil samples of the Baer knolls, the dominant forms of which was filamentous and heterocyst. The study of the cyanobacteria effect on increasing in the rate of fertility found that in all soil samples with cyanobacterial cultures was an increase the mass fraction of organic matter and pH of the water extract after three months of exposure.
