V111G1dl JCIICJ LCJI:l II7UUll - 11llV1 JCIICJ <br />• <br />LOCATION KIM CO+KS MT NM WY <br />Established Series <br />Rev. AJC/GB/PRF <br />01/2000 <br />KIM SERIES <br />P2L~C 1 Vl J <br />The Kim series consists of very deep, moderately permeable, well drained soils that formed in alluvium <br />and mixed eolian and alluvial material derived from sandstone and shale. Kim soils are on alluvial fans <br />below escarpments of sedimentary rock and uplands. Slopes are 0 to 20 percent. The mean annual <br />precipitation is about 13 inches and 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 - gassland. (Colors are for dry soil unless otherwise noted.) <br />A--O to 6 inches; gayish brown (lOYR 5/2) loam, dark grayish brown (lOYR 4/2) moist; moderate very <br />fine granular structure; soft, very friable; strongly effervescent; moderately alkaline (pH 8.0); cleaz <br />smooth boundary. (4 to 8 inches thick) <br />AC-6 to 14 inches; gayish brown (lOYR 5/2) clay loam, dark gayish brown (IOYR 4/2) moist; weak <br />medium prismatic structure parting to weak medium subangular blocky; hard, very friable, plastic; <br />violently effervescent; moderately alkaline (pH 8.0); clear wavy boundary. (6 to 10 inches thick) <br />C-14 to 60 inches; pale brown (lOYR 613) clay loam, brown (lOYR 5/3) moist; massive; hard, very <br />friable; 5 percent sandstone fragments; some visible calcium carbonate occurring as small soft masses; <br />violently effervescent; moderately alkaline (pH 8.0). <br />TYPE LOCATION: Bent County, Colorado; 50 feet west and .85 mile south of the northwest comer of <br />Sec. 3, T. 26 S., R. 52 W. <br />RANGE IN CHARACTERISTICS: Mean annual soil temperature ranges from 49 to 58 degees F., <br />and mean summer soil temperature ranges from 59 to 78 degees F. The surface 15 inches has <br />approximately .8 percent organic matter and the sand/clay ratio ranges from 1 to about 3. The particle- <br />size control section is typically loam, sandy clay loam, or light clay loam, and less commonly in the <br />lower part a fine sandy loam. It has 18 to 35 percent clay, 20 to 55 percent silt, and 15 to 60 percent <br />sand, with more than 15 percent but less than 45 percent being fine or coarser sand. Rock fragments are <br />typically less than 10 percent and range from 0 to 15 percent. Exchangeable sodium percentage is <br />usually less than 3 and is less than IS in any layer as thick as 4 inches. This soil is not dry in all parts of <br />the moisture control section for more than one-half the time that the soil temperature is above 41 degees <br />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 b moist <br />Chroma: 2 through 4 <br />Structure: ganulaz structure, but has subangular blocky structure in some pedons. <br />http://www.statlab.iastate.edu/soils/osd/dat/K/KIM.html 6/25/02 <br />
