U. S. BURFjAU OF SOII� CLASSIFICATIOPI SYSTEM
We use the U. S, Bureau of Soils method of soil classification which is based on the
texture of the soil. The texture of a soil is influenced by the amaunt of the various
sizes of soil particles in the soil. The soil particles are grouped into three
pa.rticle size classifications as followse
Particle-Size niameter of U. S. Standard
Classification Particles(Millimeters) Sieve
Sand 2.0 to Oo05 #10 to #270
Silt 0.05 to 0,005 (Gannot be sepa.rated
Clay Smaller than 0.00$ by sieving)
Soil is grouped into twelve
silt and clay present in the
triaxial graph�
bas�c classifications according to the percentages of san,d,
soil. These classifications are shown by the following

We classify the sand present in a soil as coarse (��10 - i�20 s�eves), medium (#20 -�4,0
sieves), fine (#40 -#100 sieves), very fine (#100 -#270 sieves), or as well graded.
Soils with an appreciable amount of gravel present are classified "with a little gravel"
(less than 15�), "with some gravel" (15 to 30;b)� "with gravel" (30 to 5(3�), "and gravel"
(over 50�). Material over 3 inches is classified as boulderse Organic soil is'classified
as"peat" (over 2�3 organ�material) or "muck" (1/3 to 2��rganic material},•
(3-15-6i)
