Custom Soil Resource Report <br /> Soil Reports <br /> The Soil Reports section includes various formatted tabular and narrative reports <br /> (tables) containing data for each selected soil map unit and each component of each <br /> unit. No aggregation of data has occurred as is done in reports in the Soil Properties <br /> and Qualities and Suitabilities and Limitations sections. <br /> The reports contain soil interpretive information as well as basic soil properties and <br /> qualities.A description of each report(table) is included. <br /> Soil Physical Properties <br /> This folder contains a collection of tabular reports that present soil physical properties. <br /> The reports(tables)include all selected map units and components for each map unit. <br /> Soil physical properties are measured or inferred from direct observations in the field <br /> or laboratory. Examples of soil physical properties include percent clay, organic <br /> matter, saturated hydraulic conductivity, available water capacity, and bulk density. <br /> Physical Soil Properties (Russell Painter ) <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 less 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 /> The content of sand, silt, and clay affects the physical behavior of a soil. Particle size <br /> is important for engineering and agronomic interpretations, for determination of soil <br /> hydrologic qualities, and for soil classification. <br /> The amount and kind of clay affect the fertility and physical condition of the soil and <br /> the ability of the soil to adsorb cations and to retain moisture. They influence shrink- <br /> 21 <br />
