Custom Soil Resource Report <br /> Sandy spot(map symbol) <br /> A spot where the surface layer is loamy fine sand or coarser in areas where the <br /> surface layer of the named soils in the surrounding map unit is very fine sandy <br /> loam or finer. <br /> Sapric soil material (muck) <br /> The most highly decomposed of all organic soil material. Muck has the least <br /> amount of plant fiber, the highest bulk density, and the lowest water content at <br /> saturation of all organic soil material. <br /> Saturated hydraulic conductivity (Ksat) <br /> The ease with which pores of a saturated soil transmit water. Formally, the <br /> proportionality coefficient that expresses the relationship of the rate of water <br /> movement to hydraulic gradient in Darcy's Law, a law that describes the rate of <br /> water movement through porous media. Commonly abbreviated as "Ksat." <br /> Terms describing saturated hydraulic conductivity are: <br /> Very high: 100 or more micrometers per second (14.17 or more inches per <br /> hour) <br /> High: 10 to 100 micrometers per second (1.417 to 14.17 inches per hour) <br /> Moderately high: 1 to 10 micrometers per second (0.1417 inch to 1.417 inches <br /> per hour) <br /> Moderately low:0.1 to 1 micrometer per second (0.01417 to 0.1417 inch per <br /> hour) <br /> Low: 0.01 to 0.1 micrometer per second (0.001417 to 0.01417 inch per hour) <br /> Very low: Less than 0.01 micrometer per second (less than 0.001417 inch per <br /> hour). <br /> To convert inches per hour to micrometers per second, multiply inches per hour <br /> by 7.0572. To convert micrometers per second to inches per hour, multiply <br /> micrometers per second by 0.1417. <br /> Saturation <br /> Wetness characterized by zero or positive pressure of the soil water. Under <br /> conditions of saturation, the water will flow from the soil matrix into an unlined <br /> auger hole. <br /> Scarification <br /> The act of abrading, scratching, loosening, crushing, or modifying the surface to <br /> increase water absorption or to provide a more tillable soil. <br /> Sedimentary rock <br /> A consolidated deposit of clastic particles, chemical precipitates, or organic <br /> remains accumulated at or near the surface of the earth under normal low <br /> temperature and pressure conditions. Sedimentary rocks include consolidated <br /> equivalents of alluvium, colluvium, drift, and eolian, lacustrine, and marine <br /> deposits. Examples are sandstone, siltstone, mudstone, claystone, shale, <br /> conglomerate, limestone, dolomite, and coal. <br /> 63 <br />
