Hydrometer analysis is effective for soil fractions down to about 0.5 µm (Das 1994). ... clay deposits exist at LI greater than 1 (i.e., at in situ water content greater than LL). Fine grained soils often contain clays and silts. Here, clays are plastic and silts are non- WitrynaSoil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management. Many of the physical and chemical properties of the soil depend on how fine (clayey ... fiber optic cable enclosures
