SOILS INFORMATION <br />3. A = 0-5 inches; sandy loam, 30 $ clay, very dark grayish <br />brown lOYR 3/2 moist, non-calcareous, pH = 7.8, <br />AC = 5 to 10 inches; sandy loam, 10 $ clay, dark grayish <br />brown lOYR 4/2 moist, strongly effervescent, pH = 8.0, <br />weak medium prismatic parting to weak medium subanqular <br />block structure. <br />Ck = 10 to 53 inches; loamy sand, 3 $ clay, brown lOYR 5/3 <br />moist, strongly effervescent, pH 8.2, few fine <br />carbonate filaments and soft masses, massive. <br />Due to dryness, I could not auger deeper than 53 inches. <br />This site was mapped soil symbol 112: <br />Ustic Torriorthents. This is a broadly defined unit <br />in Logan County; however, this soil falls with in <br />the range of this map unit. The soils are light <br />colored, thin surface, and sandy loam textures. <br />4. A = 0 to 5 inches; sandy loam, very dark grayish brown lOYR <br />3/2 moist, non-calcareous, pH = 7.6. <br />Bt = 5 to 12 inches, clay loam, 30 percent clay, very dark <br />grayish brown iOYR 3/2 moist, non-calcareous, pH = 7.8, <br />strong medium angular blocky structure. <br />Bkl =12 to 15 inches; loamy brown 10YR 4/3 moist, strongly <br />alkaline, pH = 8.0. <br />Bk2 =15 to 2i inches; loam, brown lOYR 5/3 .moist, violently <br />effervescent, pH = 9.0, weak fine and medium platy <br />structure. <br />Bk3 =21 to 26 inches; loam, brown lOYR 5/3 moist, strongly <br />effervescent, pH = 8.8, many fine and medium soft <br />carbonate masses and filaments, weak fine and medium <br />platy structure. <br />Bk4 =26 to 28 inches; loam, brown 10YR 5/3 moist, strongly <br />effervescent, pH = 8.8 weak fine and medium platy <br />structure. <br />Could not auger deeper than 28 inches. There may be soft <br />rock underneath. There appeared to be some evidence of <br />rock structure below this horizon. <br />This site was mapped 24 - Dix-Altvan complex, 9 to 25 <br />percent slopes. <br />Summary <br />Site 1: The depth of topsoil is about 16 inches thick for <br />reclamation use. The soil material below 16 inches would probably <br />still support plant growth, but it has a little higher pH as well as <br />lower organic matter content. <br />Site 2: The depth of topsoil is about 30 inches thick for <br />reclamation use. The soil below to inches would still support plant <br />growth. As in site 1, roots would still penetrate this material. <br />
