Knowledge of moisture content is crucial in assessing spatial and temporal movement of water through
the unsaturated zone. Moisture storage is also important for monitoring the soil water balance and for validation of
water balance models. The purpose of this work was to determine and analyse moisture content profiles at point
locations in the unsaturated zone of a lateritic soil around Nsimi, south of Cameroon. Neutron probe has been connected
to a set of tensiometers in an area of 60 ha. A comparative study between a site covered with vegetation and a site
uncovered was conducted to assess the influence of vegetation in the process of moisture transfers. The results showed
that the spatial distribution of moisture profiles varied according to the site and the texture of the soil, with in general
increasing of moisture from the surface horizon toward the deeper layers. The mean values of moisture varied from èm=
0,397 cm3/cm3 on barren site, against èm= 0,429 cm3/cm3 in vegetation. Values of suction were generally strong in surface
and at depth, but weak in the intermediate layers.
