<br />104 - Fort Collins Variant, 2 to 6 percent sl <br />The Fort Collins Variant soil is deep and well-drained. <br />It developed from shale and sandstone alluvium. Small areas <br />of Rombo Taxajunct and Embry soils were included in mapping. <br />Rombo Taxajunct soils are moderately deep. Embry soils are <br />deep but less highly developed and have fewer coarse <br />fragments. These soils occupy less than 15 percent of the <br />mapping unit. <br />In a typical profile, the surface layer is dark grayish <br />brown flaggy loam about 7 inches thick. The upper subsoil <br />is grayish brown to brown loam about 17 inches thick. The <br />lower subsoil is yellowish brown clay loam to silt about <br />• 28 inches thick and is underlain with cobbly and stony, <br />loam-textured alluvium below about 52 inches. <br />The Fort Collins Variant soil has moderate permeability <br />and medium runoff. The erosion hazard is low to moderate. <br />Available water holding capacity is high. Effective rooting <br />depth is 40 to 60 inches. <br />This soil is used for livestock grazing and wildlife <br />habitat. The vegetation is primarily blue grama, western <br />wheatgrass, pinyon pine and juniper. <br />. - ;`~~r~~"~~~~1~~~'~6`'~di:i~'''d~'t,"e~'I''a"2~"Y'~++k2 <br />£~ This material is rated fair to good with suitability <br />decreasing with depth due to increasing rock fragment <br />content. <br /> <br />
