摘要

Facilities of application of an experiment in nature for soil evolution investigation are considered. They are exemplified by long-term studies of soil resilience in an experiment simulating shifts in natural zones pattern. Changes in intensities of substances fluxes through the soil start in the first 3-5 years, whereas considerable quantitative alterations have been reported after 15-18 years. Basic trends of processes in soils that had been functioning under similar conditions did not seriously change; in soil subjected to drastic alterations of hydrothermic regimes, processes operative in them depend on soil genesis and initial soil features.
