FIELD: technological processes.
SUBSTANCE: invention can be used for experimental development of technology of nitrogen fertilizers for plants in Mars conditions. Invention consists in that space of pressure chamber is filled with gas medium imitating Martian atmosphere by chemical composition, pressure and content of dust particles corresponding to size and chemical composition of Martian dust. Nitrogen-fixing bacteria are placed in the space of the pressure chamber, the temperature of the imitating gaseous medium is maintained at a level corresponding to the temperature of normal vital activity thereof, and nitrogen content is periodically measured in the simulating gaseous medium.
EFFECT: enabling investigation of nitrogen fertilizers for plants based on the Martian atmosphere.
