Description
Monthly changes in plant biomass, net primary productivity and transfer dynamics of tropical grazing land of western Ghats region, southern India, are presented. The annual above- ground net production was 9.03 g/m2/day and the below-ground net production was 2.56 g/m2/day. Total annual net primary production was estimated at 4232 g/m2/day. Of the total input of 11.59 g/m2/day into the system, about 77.9% was channelled to above-ground and 22.1% to belowground, The rate of litter disappearance was 0.55 g/m2/day and l.14 g/ m2/day for below-ground disappearance. The total output was 1.69 g/ m2/day which was 14.6% of the total input. Thus, the grazing land showed a net accumulation of surplus organic matter, indicating the semi nature of this grazing land. The trends of biomass pattern and transfer dynamics in the above grazing land is discussed.
