Аннотация:Technogenic barren lands formed under the influence of sulfur dioxide and heavy metal emissions
near nonferrous metallurgy enterprises on the Kola Peninsula are characterized by inhibited CO2 emission from soils (10–30 mg C m–2 h–1, or 12–26 g C m–2 summer–1). Remediation of barren lands promotes the growth of plant roots and microorganisms, the respiration of which accelerates the flow of CO2 from the soil by half at chemophytostabilization and five times at application of the fertile layer; at this, the proportion of root respiration increases from 0 to 40–60%. The intensity of CO2 emissions by soils and the structure of its production can be used as criteria for remediation effectiveness of technogenic barren lands.
