Studies on the influence of industrial pollution on soil animals in pine stands, aims and methods of the soil-block model experiment
During previous studies (Górny, 1971, 1972) it was inferred that industrial air pollution exerts a marked influence on soil animal populations in pine stands. It was also stated that an initially slight positi...
