333.T1 Model Agricultural Core Curriculum: Supplement University of California, Davis Influence of Texture on Soil Sand Sand is made up of small coarse pieces of rock. Particles range in size from 2.00 mm to 0.5 mm.

333.T2 Model Agricultural Core Curriculum: Supplement University of California, Davis Influence of Texture on Soil Silt Silt is made up of small flour-like “soil separate.”. Particles range from.05 mm to.002 mm.

333.T3 Model Agricultural Core Curriculum: Supplement University of California, Davis Influence of Texture on Soil Clay Clay appears plate-like in shape. Particles fit closely together with little space between. Clay particles are.002 mm or less.

333.T4 Model Agricultural Core Curriculum: Supplement University of California, Davis Influence of Texture on Soil Soil Profile Soil profile is the arrangement of the soil particles within various layers. These layers are called horizons. A B C

333.T5 Model Agricultural Core Curriculum: Supplement University of California, Davis Influence of Texture on Soil Soil Horizons A Horizon :Upper layer of soil. High in organic matter. Granular soil structure. B Horizon : Subsoil. Low in organic matter. Block-like/prismatic soil structure. C Horizon : Deepest soil. Very low organic matter. Coarse, rocky soil structure.
