Agriciltural microbiology| Summary: | We analyzed the functional and taxonomic structure of microbial community of dark grey soil, depending on the effects of the weather and fertilizer systems. It was shown that fallow soil is characterized by integrated and more stable microbial community compared with agroecosystems soil. However, under the effect of such abiotic factors as increased average monthly temperatures and moisture deficiency, some imbalance of trophic interactions in microbiocenosis is observed.
Agroecosystems are characterized by less stable functional and taxonomic structure of the soil, which is defined by the hydrothermal conditions of the growing season and types of fertilizers applied. This is supported by a smaller number of correlations and a simplified structure of correlation pleiades of the soil of agroecosystems during unfavourable periods of vegetation periods, especially in the soil without fertilizers and using only mineral fertilizers. The use of organic and mineral fertilizer system brings the state of the soil microbiocenosis of agroecosystems soil to that of fallow soil. |
