Examples of soil physical properties include percent clay, organic <br />matter, saturated hydraulic conductivity, available water capacity, and bulk density. <br />Physical Soil Properties (Bucklen Pit 11/2012) <br />This table shows estimates of some physical characteristics and features that affect <br />soil behavior. These estimates are given for the layers of each soil in the survey area. <br />The estimates are based on field observations and on test data for these and similar <br />soils. <br />Depth to the upper and lower boundaries of each layer is indicated. <br />Particle size is the effective diameter of a soil particle as measured by sedimentation, <br />sieving, or micrometric methods. Particle sizes are expressed as classes with specific <br />effective diameter class limits. The broad classes are sand, silt, and clay, ranging from <br />the larger to the smaller. <br />Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to 2 <br />millimeters in diameter. In this table, the estimated sand content of each soil layer is <br />given as a percentage, by weight, of the soil material that is less than 2 millimeters in <br />diameter. <br />Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05 millimeter <br />in diameter. In this table, the estimated silt content of each soil layer is given as a <br />percentage, by weight, of the soil material that is less than 2 millimeters in diameter. <br />Clay as a soil separate consists of mineral soil particles that are Tess than 0.002 <br />millimeter in diameter. In this table, the estimated clay content of each soil layer is <br />given as a percentage, by weight, of the soil material that is less than 2 millimeters in <br />diameter. <br />24 <br />
