摘要: Knowledge of moisture content is crucial in assessing spatial and temporal movement water through the unsaturated zone. Moisture storage also important for monitoring soil balance validation models. The purpose this work was to determine analyse profiles at point locations zone a lateritic around Nsimi, south Cameroon. Neutron probe has been connected set tensiometers an area 60 ha. A comparative study between site covered with vegetation uncovered conducted assess influence process transfers. results showed that distribution varied according texture soil, general increasing from surface horizon toward deeper layers. mean values θ m = 0,397 cm 3 /cm on barren site, against 0,429 vegetation. Values suction were generally strong depth, but weak intermediate
