Microbial succession in the typical chernozems of "Streletskaya steppe" reserve under the influence of long agrogenic impact

For assession the ecological status of chernozems in agrocenoces the indicators of biological activity are most informative. It was revealed that the direction of microbial succession at plowing of virgin chernozems depend on the method of its use. In crop rotation, the microbial community moves into adaptive stress zone, such changes can be regulated by agricultural techniques. In a long fallow to zone of resistance. In the arable soil species structure of micromycetes are changing. In the absence of plants the rank of fungihydrolitics are declining. Indicator fungies species for different biocenoces were revealed.
