Abstract

The most important indicators of biological activity (respiration, methane genesis, nitrogen fixation, denitrification, and size and structure of the microbial population) were determined in coprolites of two types of earthworms (Lumbricus rubellus considered as the “litter” type and Aporrectodea rosea as the “soil” type) in the model experiment, in which the earthworms were kept separately and together, as in soddy-podzolic loamy soil. The biological activity of coprolites was significantly higher than in the soil and varied between worm species.
