26 <br /> road is reddish sandy clay loam with high lime content. Stockpile <br /> 10 is a small isolated pile just off the southwest corner of the <br /> tract. <br /> Analysis of the stockpiles show no serious limitations to their use. <br /> Table 6 shows the ccn posited data from 3 samples of each stockpile <br /> on the assumption that mixing within each stockpile will inevitably <br /> occur on 'respreading. Stockpiles 1, 2, 3 and 6 are dcminately <br /> sandy loms with percent of clay ranging from 13.8% to 19.7%. All <br /> other st(x*piles are dcmi.nately sandy clay loams with clay content <br /> ranging from 20.7% to 33.8%. Alkalinity and salinity are low in all <br /> tests. Cat-O. equivalent ranges from 2.9% to 9.1%. Cccmputed sulfates <br /> range frtri 00-900 parts per million (expressed as So4) . <br /> Ma s and Their Uses <br /> The basic soil survey is shown on clap 1 at a scale of 1 inch = 400 <br /> feet. Descriptions of the soil map units and their characteristics <br /> have been described in this report. <br /> Map 2 is a topsoil-stripping isopach showing the depths of stripping <br /> that would provide usable topsoil materials. The location and ex- <br /> tent of each is shown and the symbol in each area designates strip- <br /> ping depth, quality and limitations to stripping or quality. <br /> A coiposite symbol is used to designate recommended stripping depths <br /> in each area. The symbols in the numerator shows the better <br /> quality of topsoil available and the depths of cut permissible. The <br /> symbols in the denominator shows the probable usable depth of cut but <br /> would provide material, when mixed, of lower quality. The small <br /> letter subscript is used to indicate the factors which reduce quality <br /> of the material when stripped to the deeper limits. Any deeper <br /> cutting than this is not advised because the depths to sandstone and <br /> shale vary considerably. There is greater risk of incorporating <br /> shale and sandstone below the depths specified in Map 2 and Tables 1, 2 <br /> and 3. <br />
