Hydrometer analysis is useful for turf or dirt surfaces because it is used to calculate particle diameter of fine-grained particles (silts and clays) that are too small for sieve analysis. Using a hydrometer for soil analysis is based on Stoke’s law and measures the rate of sedimentation in a water suspension. This method will also help to break clay and silt particles down when two or more grains have joined together.
