Understanding Soil Texture and Structure
... • A. Soil texture is the fineness or coarseness of a soil. It describes the proportion of three sizes of soil particles. These are: • 1. Sand—large particle • 2. Silt—medium-sized particle • 3. Clay—small particle • B. Texture is important because it affects: • 1. Water-holding capacity—the ability ...
