Soil moisture measured at 50 cm above vetiver hedgerow showed that soil moisture content
of an experimental plot with vetiver hedgerow was higher than that of a plot without vetiver hedgerow
and a close hill spacing treatment conserved more moisture in the soil better than that with wider hill
spacing, particularly at the end of the rainy season in October or November. This indicated that vetiver
hedgerows conserve soil moisture better (Fig. 5).
