Influence of biochar on the taxonomic composition and structure of prokaryotic communities in agro soddy-podzolic soil

Currently the scientific literature is actively discussing the feasibility of biochar using in agriculture. Biochar is one of the new types of organic meliorants. It is obtained by pyrolysis of wood or other plant waste in an inert atmosphere converting carbon compounds to a stable state. Its use is recommended to increase the soils biological activity and the agricultural crops productivity and it is actively implement in agricultural technologies of foreign countries. However many aspects of the biochar influence on the agrocenoses properties and state have been poorly studied. There is information about both positive and negative processes occuring in soils under biochar. The main concern is the data on the biochar influence on humus mineralization, since dehumification can lead to loss of soil fertility and ecological stability. This is especially important for soddy-podzolic soils characterized by a low humus content and a weak degree of humification. Such soils initially have low ecological stability and are quite vulnerable to human impact...
