The Jhum agroecosystem in north-eastern India: a case study of the biological management of soils in a shifting agricultural system

, : The Jhum agroecosystem in north-eastern India: a case study of the biological management of soils in a shifting agricultural system. The biological management of tropical soil fertility: 189-207

The Jhum system is a form of shifting cultivation practised in north-eastern India in which farmers grow a mixture of crop species for a period of 1-2 years on land in which plant nutrients have accumulated over several years under secondary fallow vegetation. The land is subsequently abandoned and undergoes secondary succession during which time soil fertility is restored.

Earthworms participated in the N cycle through worm cast...
