SOILS INFORMATION 1 USDA - NRCS 220 State St. Fort Morgan, CO 08701 March 20, 1996 Dawn Jackson, Resource Conservationist RE: Soil information for proposed gravel pit expansion as requested by Environment, inc., Arvada, Colorado. On March 11, 1996 we went out to the gravel pit to conduct a soils investigation. i looked at the soils in four locations. See the attached map. This is what I Pound at the sites: 1. A = 0 to 5 inches; sandy loam, 13 percent clay, very dark grayish brown, 30YR 3/2 moist, pH = 7.8, non-calcareous. BA = 5 to 9 inches; sandy loam, very dark grayish brown 3oYR 3/2 moist, 12 percent clay, pH = 7.8, non-calcareous. BW = 9 to 16 inches; sandy loam, brown lOYR 4/3 moist, l0 percent clay, pH = 7.8, non-calcareous, weak medium prismatic parting to weak subangular blocky structure. Bk = 16 to 32 inches; sandy loam, brown 10YR 5/3 moist, 9 percent clay, pH = 8.2, strongly effervescent, few fine lime filaments, weak medium subanqular blocky structure. Due to dryness, i could not auger below 32 inches. This soil was mapped 119 or 112. The sandy loam properties, here, fit better with 112. For the soil interpretations I would use the soil found in 112. 2. A = 0 to 4 inches; sandy loam, dark brown lOYR 3/3 moist, non-calcareous AC = 4 to 10 inches; sandy loam, brown lOYR 4/3 moist, strongly effervescent, pH = 8.2, weak medium subangular blocky structure. Ck = 10 to 38 inches; sandy loam, brown lOYR 5/3 moist, strongly effervescent, pH = 8.4, few lime coatings on pebbles, massive. Due to dryness, I could not auger deeper than 38 inches. This site was mapped soil symbol 112: Ustic Torriorthents. This is a broadly defined unit in Logan County; however, this soil falls with in the range of this map unit. The soils are light colored, thin surface, and sandy loam textures.
