Extract

1. Examinations have been made of the losses involved by igniting fractions of tropical soils.

2. It has been found that these losses are partly due to organic matter and partly to combined water; the greater part of the loss is due to water.

3. In the clay fraction there is a correlation between the amount of combined water and the silica/alumina ratio; the greater the ratio the less the combined water. This is affected by the proportion of iron present.

4. Lateritic soils lose more water on ignition than other soils but the lateritic material in soils is not necessarily evenly distributed throughout the fractions; those fractions containing the highest proportions of lateritic material lose the most water.
