FAO Soil Texture
Texture is the relative proportion of sand, silt and clay of the dominant soil for each soil map polygon. Texture classes are:
Coarse texture: sands, loamy sand and sandy loams with less than 18 % clay, and more than 65 % sand.
Medium texture: sandy loams, loams, sandy clay loams, silt loams with less than 35 % clay and less than 65 % sand; the sand fractions may be as high as 82 % if a minimum of 18 % clay is present.
Fine texture: clays, silty clays, sandy clays, clay loams and silty clay loams with more than 35 % clay.
Where two or three texture names appears, this means that all named textures are present in the map unit.
