The aim of this work was to assess and compare the influence of Eisenia foetida Savigny earthworms on C mineralization rate, labile C fractions (water-soluble C and water-soluble carbohydrates), microbial biomass C, and enzyme activities (dehydrogenase, urease, phosphatase and ß-glucosidase) in three soils of varying texture treated with a composted organic residue and cropped with Avena sativa L. Mineralization decreased with the addition of earthworms to the sandy and clay-loam soils, especially in sandy soil (by about 4 µg CO 2-C g -1 day -1). There were no significant effects on the amount of CO 2 evolved from clay soil due to the addition of E. foetida. The addition of E. foetida to sandy soil significantly decreased microbial biomass C and increased microbial metabolic quotient the qCO 2 (CO 2-C to biomass C ratio). The addition of E. foetida did not affect the microbial biomass or the qCO 2 of the clay-loam and clay soils. Open AccessPeer reviewed 7 pages, 6 tables, 1 figure.
