Title:

Role of active components in carbon and nutrient cycling of bamboo ecosystems in Indian dry tropical region.

Authors:Tripathi, S.K; Singh, K.P

Abstract:Dry matter, carbon and nutrient dynamics in mature and harvested stands ofbamboo ecosystems in Vindhyan dry tropies were studied with emphasis on the role of active components (i.e. leaves, fine roots and herbs). Bamboo harvest resulted in lowering of total net production in bamboo, but increased annual allocation to the belowground components, especially to the fine roots. Active components showed marked seasonality and contributed substantially (86-94%) to the total dry matter, carbon and nutrient additions in the soil. Dry matter. C, Nand P additions to the soil by mortality of acti ve components were substantial (90-94% of total additions). This reflects that in the nutrient limited bamboo ecosystems, the active components, because of their marked seasonality and high nutrient use efficiency, playa significant role in maintaining a fairly high net production within a short span of time, despite substantial periodical (5-7 years) nutrient export from the system in harvesting
