Auteur :
PESTALOZZI, H.

Description :
Sectoral fallow systems are commonly used in the Bolivian High Andes. Fields in the study erae (Japo, Department of Cochabamba) are cultivated for 3 years with potatoes as the first crop and then lie fallow for 9 years. A participatory research approach was used to obtain information on indigenous knowledge of farming practices. Subterranean phytomass was identifed as the key factor in nutrient storage during the fallow period. Author found farming practices to be entirely rational. - (SLD)
