<br />37 <br />Osgood Series <br /> <br />• <br />TAXONOMIC CLASSIFICATION: Loamy, mixed, mesic Arentic <br />Ustollic Raplargids. <br />The Osgood soil as mapped in the study area is des- <br />cribed as a "variant" of the typical Osgood series. The <br />typical Osgood soil as mapped in the south Weld County <br />soil survey has a thicker and finer textured subsoil than <br />the Osgood variant as mapped in the Study Area. As mapped <br />they consist of deep, well-drained soils that formed in <br />wind-laid sands. They occur on smooth plains that have <br />slopes of 0 to 3 percent. <br />Osgood soils are usually adjacent to or near Valent <br />soils which do not have a B horizon. <br />Profile description of Osgood sand, variant, 0 to <br />3 percent slope, as obtained on the study area (3400 feet <br />west and 100 feet south of the northeast corner of <br />Sec. 36, T.3N., R.64W.). (Site #1 on soil map.) <br />All -- 0 to 5 inches; brown (lOYR 5/2) sand, dark grayish <br />brown (lOYR 4/2); moist; single-grained; loose; <br />neutral; gradual smooth boundary. <br />A12 -- 5 to 18 inches, brown (lOYR 5/3) sand, dark grayish <br />brown (lOYR 4/2) moist; single-grained; loose; <br />neutral; gradual wavy boundary. <br />A3 -- 18 to 32 inches; brown (lOYR 5/3) sand, dark brown <br />(lOYR 4/3) moist; single-grained; hard when dry, <br />friable when moist; neutral; gradual smooth <br />boundary. <br />B&A -- 32 to 44 inches; brown (lOYR S/3) sand, dark brown <br />(lOYR 4/3) moist; massive; hard when dry, friable <br />moist; neutral; clear smooth boundary. <br />B2t -- 44 to 49 inches, brown (lOYR 5/3) loamy sand; dark <br />brown (lOYR 4/3) moist; moderate coarse prismatic. <br />parting to moderate medium subangular blocky <br />structure; hard, friable; neutral; clear irregular <br />boundary. <br />C -- 44 to 60 inches; pale brown (lOYR 6/31 loamy sand, <br />brown (lOYR 5/3) moist; massive; slightly hard <br />dry, very friable moist; slightly alkaline. <br />
