Agrotechnology for Snapshots Soil Health with Bacteria

Taxonomic structure of bacterial microbiome of sod-podzolic soil (Gatchina district of Leningrad region, Russia) with varying degrees of moisture were studied using pyrosequencing of 16sRNA gene. Proteobacteria were revealed mostly in drought conditions and may be used as indicator microorganisms. The fractal analysis of the data showed that the index of the biosystem determinism of the frequencies of soil microbial communities decreased with drought (from 0.73 to 0.65), since decreases the number of variations of taxonomic units, due to which a smaller number of biosystem groups were formed.
