Abstract
Soil moisture measurements in these areas illustrated an important point in the planning of tropical rotations where rainfall is a limiting factor. When the elephant grass was dug out at the end of the dry season, the soil was at or near to wilting-point to a depth of 10 ft., and contained 36 in. of water in this depth. A nearby bare fallow contained 45 in. of water in 10 ft., thus providing 9 in. of available water. Such a severe water deficit following a grass rest may seriously affect the next crop if the rainfall distribution in the early part of the growing season should be unfavourable.
