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 10 CLAY NDY CLAY 0 SILT SANDY CLAY LQAM 2p CLAY LOAM ..

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) y. � .� � � � . . . .
