Species diversity and community characteristics of earthworms in managed and degraded tea plantations of Tripura

摘要

Aim: Tea (Camelli sinensis) is an economically important and intensively managed cash crop in the northeast India. As earthworms represent the highest soil biomass and are good indicators of soil health, the main objective of the study was to find out the impact of conventional (anthropogenic interference) on earthworm biodiversity and relative density of exotic and native species in tea agro-ecosystem.
