WebNov 11, 2008 · Abstract. Determination of soil texture, particularly the clay (<2 μm) fraction, is an important measurement in most soil investigations. In this study a modified method for mechanical analysis was evaluated that eliminated the need for bulky laboratory equipment and long settling times associated with standard pipette and hydrometer methods. WebJul 8, 2024 · The hydrometer method is useful only for measuring particles with a grain diameter of 2 mm or less (sands, silts, and clays). Based on Stoke’s Law, it is known that sand size particles (0.05 mm to 2 mm) fall from suspension rapidly. Smaller silt sized particles (0.002 mm to 0.05 mm) remain in suspension longer, but eventually fall from ... chukatrin herbal powder
