Thereafter the woodlot is left as a source of fuel wood, building poles or fodder while restoring soil fertility until farmers start cutting down the trees and growing crops between the stumps 4 to 5 years later. The method was designed and developed by the South African Development Countries (SADC) and the World Agroforestry Centre(ICRAF) and their partners to alleviate rural farmers from the problems of fuelwood scarcity and poor soil fertility in the tobacco cereal land use system. The method is currently being practised at farmersâ?? fields in Tabora rural district in western Tanzania involving a large number of farmers. This study reports an assessment of litter production and seasonal pattern of Acacia crassicarpa , A. julifera , A. leptocarpa, Leucaena pallida and Senna siamea grown in rotational woodlots at five years of age
