Run-off and infiltration losses related to shifting agriculture (Jhum) in northeastern India



Run-off and infiltration losses related to shifting agriculture (Jhum) in northeastern India



Environmental Conservation 8(4): 313-321



Following slash and burn of forested fallows during shifting cultivation in northeastern India losses of Ca and Mg in windblown ash were greater under a 30 yr Jhum cycle than under a 10 or 5 yr cycle, while losses of K were greatest in the 10 yr cycle: losses of P were similar in 10 and 30 yr cycles, but markedly higher than in a 5 yr cycle. Water and sediment losses from a freshly burnt site through percolation and runoff were greater in the shorter cycles.
