12 Physical Properties Of Soil (Clay, Sand and Tilt)
As we discussed, soil is made up of clay, sand, and silt. Each of these textures in the soil has particles of different sizes. Sand particles are 2.0 to 0.05 mm in diameter, silt particles are 0.05 to 0.002 mm, and clay particles are usually less than 0.002 mm. Clay soils are the smoothest because the clay particles have the smallest diameter ...
