Introduction of earthworms to the soil under forest plantations in the Caspian Sea region


, : Introduction of earthworms to the soil under forest plantations in the Caspian Sea region. Soviet Soil Science 22(1): 20-26

Several hundred earthworms (Eisenia nordenskioldi) were released into a chernozem-like medium loam soil in a depression under an oak plantation in the semi-arid northwestern Caspian lowland, USSR. Twenty years after their introduction, soil physicochemical properties were compared with a control plot in the same depression. The introduction of earthworms did not result in acidification of the upper soil layer under the forest floor as observed in other forest plantations located nearby.
