Sesbania Sesban: Proposed Root Study in Central Province of Zambia

摘要

Sesbania sesban tree species have been investigated for adaptation to the acid soils of Central Province over the past five years. The trees have been promoted as quick maturing leguminous species to farmers and schools. Despite many adaptation studies for the past ten years little or no root dynamics and resilience of these plants to acidity and their after effects have been conducted in Central Zambia necessitating this proposed study. This proposal aims to solicit for in-depth studies in parameters that remain little understood. An analysis of the tree performances in conditions of root mass leaf drop and physical and chemical changes to date provides the impetus for these studies. The success of these ideas are qualified and questioned as we seek to address the degrading biomass problem of our tropical soils. Initial soil fertility of selected areas is presented and analysed parametrically using the basic nutrients criteria.
