Experimental microbiological recultivation of the Borodino brown coal mine dumps

Possibilities of microbiological recultivation of the Borodino brown coal mine dumps are researched. The experiment with introduction of bacterial preparation, sawdust and manure in different combination is conducted on the basis of two five-year dumps that are recultivated for agricultural and forestry use. Maximum increase in the heterotrophic microflora number throughout the vegetation period in the process of introducing the bacterial preparation combined with additional organic matter sources and manure is shown.
