Series Description <br />LOCATION KIM CO+KS MT NM WY <br />Established Series <br />Rev. AJC/GB/PRF <br />01/2000 <br />KIM SERIES <br />The Kim series consists of very deep, moderately permeable, well drained soils that formed in alluvium and mixed <br />eolian and alluvial material derived from sandstone and shale. Kim soils are on alluvial fans below escarpments of <br />sedimentary rock and uplands. Slopes aze 0 to 20 percent. The mean annual precipitation is about 13 inches and <br />the mean annual temperature is about 51 degrees F. <br />TAXONOMIC CLASS: Fine-loamy, mixed, active, calcareous, mesic Ustic Torriorthents <br />TYPICAL PEDON: Kim loam -grassland. (Colors are for dry soil unless otherwise noted.) <br />A--O to 6 inches; grayish brown (lOYR 5/2) loam, dark grayish brown (lOYR 4/2) moist; moderate very fine <br />granular structure; soft, very friable; strongly effervescent; moderately alkaline (pH 8.0); cleaz smooth boundary. <br />(4 to 8 inches thick) <br />AC--6 to 14 inches; grayish brown (1 OYR 5/2) clay loam, dazk grayish brown (1 OYR 4/2) moist; weak medium <br />prismatic structure parting to weak medium subangulaz blocky; hazd, very friable, plastic; violently effervescent; <br />moderately alkaline (pH 8.0); cleaz wavy boundary. (6 to 10 inches thick) <br />C--14 to 60 inches; pale brown (lOYR 6/3) clay loam, brown (lOYR 5/3) moist; massive; hard, very friable; 5 <br />percent sandstone fragments; some visible calcium carbonate occurring as small soft masses; violently <br />effervescent; moderately alkaline (pH 8.0). <br />TYPE LOCATION: Bent County, Colorado; 50 feet west and .85 mile south of the northwest corner of Sec. 3, <br />T. 26 S., R. 52 W. <br />RANGE IN CHARACTERISTICS: Mean annual soil temperature ranges from 49 to 58 degrees F., and mean <br />summer soil temperature ranges from 59 to 78 degrees F. The surface IS inches has approximately .8 percent <br />organic matter and the sand/clay ratio ranges from 1 to about 3. The particle-size control section is typically loam, <br />sandy clay loam, or light clay loam, and less commonly in the lower part a fine sandy loam. It has 18 to 35 percent <br />clay, 20 to 55 percent silt, and 15 to 60 percent sand, with more than 15 percent but less than 45 percent being <br />fine or coarser sand. Rock fragments are typically less than 10 percent and range from 0 to 15 percent. <br />Exchangeable sodium percentage is usually less than 3 and is less than 15 in any layer as thick as 4 inches. This <br />soil is not dry in all parts of the moisture control section for more than one-half the time that the soil temperature is <br />above 41 degrees F. (225 to 235 days) and is not dry for 45 consecutive days following July 15. <br />A horizon <br />Hue: SY through 7.SYR <br />Value: 5 through 7 dry, 3 through 6 moist <br />Chroma: 2 through 4 <br />http://ortho.ttw.nres.asda.gov/cgi-bin/osd/osdname.egi?-P Page 1 of3 <br />
