The study of the postpyrogenous and background plot
state of light- and twenty-year lea lands has been shown
that an influence of fire occurs on different mechanisms
every three and fourteen months after its passing. The
general processes that take place on account of fire after
three months are following: a decrease of the amount of
microorganisms, their physiological and biochemical
activity, the carbon and nitrogen compound migration
intensification with the exception of humus, an increase
of soil phytotoxicity. After fourteen months the
mentioned tendencies remain apart, from humus decay
activity and phytotoxicity- they are reduced.
