ECOLOGO-MICROBIOLOGICAL SOIL MONITORING IN THE VICINITY OF A CHEMICAL-PLANT

Soils of the area (42 sq. km) adjacent to the chemical combine ''Khimv olokno'' in Mogilev city (Belarus) have been investigated. Sampling si tes were concentrated along 11 radii in the 3-km-wide zone around the combine. The rate of substrate-induced and basal soil respiration have been determined in fresh samples, with a subsequent calculation of th e metabolic coefficient. Agricultural land use types are shown to affe ct the soil microbiological properties stronger than the polluting fal lout. A system of indices is proposed for the ecologic-microbiological soil monitoring, it permits revealing and assessing the anthropogenic targets on the soil, as well as giving forecasts and advice for susta inable land use.
