The world demand for restoring technologies of anthropogenically disturbed soil fertility and increasing crop yields emerges primarily from the active transition to a new paradigm in the field of agro-technologies. In this regard, many countries of the world are potential markets for new technologies of humusproduction and creation of eco-black-earths (chernozems). For the production of humus, it is intendedto use lignite (brown coal) as the raw material, which is rich in humic acids. By familiarizing ourselveswith the coal nature, we selected lignite (oxidized) samples for further experiments. Based on the understanding of coal and microorganisms, we selected lignite which are from different areas of Kazakhstancoal-mines, and different types of bacteria. FTIR was used to analyze the content of humic substancestreated by different bacteria. A bacterial strain RBK 7 was used to decompose a coal sample, as a result,the humic acid was extracted and applied to the planting process of coriander, and it was found that acertain concentration of humic acid could improve soil fertility and the germination rate of this plant.Key words: lignite, bacteria, humic acid, FTIR.
