SOIL SEPARATES: The names and size limits of separates recognized by pedologists in Canada and the United States are: very coarse sand, 2.0 to 1.0 mm coarse sand, 1.0 to 0.5 mm medium sand, 0.5 to 0.25 mm fine sand, 0.25 to 0.10 mm very fine sand, 0.10 to 0.05 mm silt,0.05 to 0.002 mm clay, less than 0.002 mm fine clay, less than 0.0002 mm http://sis.agr.gc.ca/cansis/glossary/separates,_soil.html
