Abstract

Biomass variation, secondary production and turn-over of the earthworm Drawida willsi (Michaelsen) was assessed from a tropical agroecosystem site at Ranchi for 18 months. The total biomass ranged between 0.88 ± 0.33 and 29.55 ± 3.15 g dry weight m^-2. Secondary production of 53.37 g dry weight m^-2 yr^-1 was obtained which in terms of calorific value amounts to 246.57 kcal m^-2 yr^-1. Biomass turnover value was 4.99.
