Soil texture refers to the relative proportion of sand, silt and clay size particles in a sample of soil. Clay size particles are the smallest being less than .002 mm in size. Silt is a medium size particle falling between .002 and .05 mm in size.

silt sized quartz, kaolinite and bentonite in accordance with ASTM D854 – 14 standards were found to be 2.65, 2.65, 2.60, 2.55 and 2.45, respectively. The mixtures were oven-dried for 24 h at 105 °C before mixing. The dry mixtures were prepared by mixing clay and sand in dry state until a homogeneous clay–sand distribution was observed.

Gravel sized particles being the largest and clay sized being the smallest. Do notice that we have written Silt size and Clay size, not only the Silt and Clay because these are the range of sizes not the actual soils Silt and Clay which exhibit properties of plasticity and cohesion. Not all the clay sized particles are clay particles.

Sand, which is influenced more by particle size, is subdivided into four categories – fine, medium, coarse, and very coarse. A new soil category, Mo, has been introduced that has a particle size of 0.02-0.1 mm and is finer than sand and coarser than silt. Silt and clay have the respective particle size range of 0.002-0.02 mm and 0.0002-0.002 mm.
