LAN <br /> 01/2014 <br /> KIMERA SERIES <br /> The Kimera series consists of very deep,well drained soils that formed in alluvium and eolian deposits derived <br /> from sedimentary rock. Kimera soils are on plains, interfluves,ridges, fans, and hills. Slopes range from 0 to 9 <br /> percent. Mean annual precipitation is about 330 millimeters (13 inches) and the mean annual temperature is <br /> about 11 degrees C (52 degrees F). <br /> TAXONOMIC CLASS: Fine-loamy, mixed, superactive,mesic Ustic Haplocalcids <br /> TYPICAL PEDON: Kimera loam, on a west-facing, 5 percent slope in rangeland at an elevation of 1,434 <br /> meters(4,705 feet). (Colors are for dry soil unless otherwise noted.) When described on August 23, 2002 the soil <br /> was moist from 0 to 10 centimeters. <br /> A--O to 10 centimeters (0 to 4 inches); brown(IOYR 5/3) loam,brown(IOYR 4/3)moist; moderate fine granular <br /> structure; soft, very friable, slightly sticky and slightly plastic; many very fine to medium roots; 1 percent <br /> calcium carbonate equivalent, strongly effervescent; moderately alkaline; clear smooth boundary. ( 8 to 15 <br /> centimeters thick) <br /> Bw--10 to 36 centimeters (4 to 15 inches);pale brown(IOYR 6/3) loam,brown(IOYR 4/3) moist; weak fine <br /> and medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; many very <br /> fine and fine roots; violently effervescent, 7 percent calcium carbonate equivalent; moderately alkaline; clear <br /> smooth boundary. (20 to 46 centimeters thick) <br /> Bk1--36 to 71 centimeters (15 to 28 inches); very pale brown(IOYR 7/3) clay loam,brown(IOYR 5/3)moist; <br /> weak medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; many very <br /> fine roots; 2 percent fine, distinct, irregular carbonate masses throughout; violently effervescent, 16 percent <br /> calcium carbonate equivalent; moderately alkaline; clear smooth boundary. <br /> Bk2--71 to 119 centimeters (28 to 47 inches); very pale brown(IOYR 7/3)clay loam,brown(IOYR 5/3) moist; <br /> weak fine and medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; few <br /> very fine roots; 17 percent fine distinct irregular carbonate masses throughout; violently effervescent, 18 percent <br /> calcium carbonate equivalent; moderately alkaline; abrupt smooth boundary. <br /> Bk3--119 to 145 centimeters (47 to 57 inches); light brownish gray(IOYR 6/2) silt loam, dark grayish brown <br /> (1 OYR 4/2) moist; moderate medium subangular blocky structure; hard, friable, slightly sticky and slightly <br /> plastic; few fine roots; few patchy faint pressure faces on vertical faces of peds; 5 percent medium distinct <br /> irregular carbonate masses throughout; violently effervescent, 15 percent calcium carbonate equivalent; <br /> moderately alkaline; abrupt smooth boundary. (Combined thickness of the Bkl, Bk2 and Bk3 horizons is 79 to <br /> 124 centimeters) <br /> Bk4--145 to 200 centimeters (57 to 79 inches); very pale brown(IOYR 7/3) loam, brown(IOYR 4/3)moist; <br /> weak medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; 4 percent <br /> medium distinct irregular carbonate masses throughout;violently effervescent, 9 percent calcium carbonate <br /> equivalent; moderately alkaline. <br /> https:Hsoilsedes.sc.egov.usda.gov/OSD—Docs/KIKIMERA.html 1/4 <br />
