Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm … WitrynaThese texture differences are the result of fineness or coarseness of particles in the soil. A given texture will have a definable range of clay (i.e. < 0.002 mm), silt (i.e. 0.002 - 0.02 mm) and sand (i.e. 0.02 - 2 mm). A special triangular graph is available where texture can be related to likely clay%, silt% and sand% The effect of particle size
