The particle size distribution of soil containing a significant number of finer particles (silt and clay) cannot be performed by sieve analysis. The hydrometer analysis is a widely used method of obtaining an estimate of the distribution of soil particle sizes from the #200 (0.075 mm) sieve to around 0.001 mm. The data are plotted on a semi-log ...
