Objectives: In this article adsorption of nitrogen in peat humic acids of Middle Ob Region of Western Siberia is being researched for the first time. Methods: Unit area of the adsorption surface defined by methods of Langmuir and Brunauer, Emmett and Teller (BET). Finding: It is established that the size of the adsorption surface of humic acids has a close connection to the extent of primary sources decomposition of humiliation. And changes in the following decreasing sequence (humic acids of sedge and grass peat, with a degree of decay of 55%>; humic acids of wood, sedge, and the sphagnum peat with the extent of decomposition of 30-35%>. Humic acids of sphagnum and wood peat with the extent of decay of 20-25%) and is characterized by the highest manifestation of peat humic acids with the extent of decomposition of 55%. Conclusion: The best adsorption properties distinguish exemplars with a greater degree of decomposition and mean value of the effective diameter of adsorption time 247-272 Å.
