Soil organic matter and nutrient dynamics under different land use histories in North Cameroon: implications on the sustainability of the environment
05 / 2001 - unknown
Context: Study of the sustainability of the major types of land use in the semi-arid North Cameroon, in support of land use planning. Aim: Identification of the impacts of various types of land use on chemical and physical soil properties controlling soil fertility, and of alternative methods to sustain or improve this fertility, with particular emphasis on the role of organic matter. Methods: Comparative study of plots, soil chemical and physical analyses, size fractionation of organic matter, experimental study of litter decomposition. Topics: Decomposition of above- and below-ground litter (crops and trees), properties and origin of organic matter fractions (size fractions), potential for agro-forestry, impacts of various types of land management.
