Features of development of the microorganisms included in the integrated bio-fertilizer under different soil moisture

Presents the influence of different moisture levels (10%, 45%, 60% field capacity) gray forest and chernozem soils of the Republic of Tatarstan on the viability and population dynamics of microorganisms that make up the consortium and integrated bio-fertilizer. The consortium of microorganisms generated from a regional nitrogen-fixing (Azotobacter chroococcum, Pseudomonas brassicacearum) and phosphate- mobilizing (Sphingobacterium multivorum, Achromobacter xylosoxidans) microorganisms. Based on it with the addition of nanostructured water phosphate suspension in a dose of 0.1 t/ha to create a comprehensive bio-fertilizer. Diazotrophic microorganisms belonging to the consortium and integrated bio-fertilizers, during the whole observation period (60 days) and maintain their viability in drought conditions - 10% soil moisture. On gray forest soil, the incorporation of microorganisms (a consortium and integrated bio-fertilizer) does not matter. That made the soil microorganisms are able to maintain their presence within two months, according to data and quantify diazotroph under 45 and 60% humidity. The efficiency of nitrogen-fixing root growth is more pronounced on the gray forest soil regardless of the type of application - in the composition of the consortium or complex fertilizer. On the black soil micro-organisms contained in the integrated bio-fertilizers, has shown great ability for long-term survival. From phosphate-mobilizing microorganisms included in the composition of the consortium and integrated bio-fertilizer, the number at any level of hydration is significantly higher than the nitrogen. An interesting trend identified for these organisms, which are included in integrated bio-fertilizer. They are more effectively stored in all the studied moisture levels. It should be noted a higher number of phosphate-mobilizing microorganisms on the black soil compared to grey forest in the complex of bio-fertilizers in 45-60 days. Thus, a consortium of integrated bio-fertilizer guaranteed to be able to withstand the reduction in moisture content (10% field capacity) up to 45 days in gray forest and chernozem soils.
