Principle

The sizes of the soil particles and the proportions of them are of great importance for the profitable use and fertility of the soil. A rough separation of soil particles according to their size, and an assessment of the proportions of them, can be made by suspending them in water. The soil particles subsequently settle according to their speed of sedimentation-
