10/13/2016 Official Series Description- MANVEL Series LOCATION MANVEL CO+KS NE SD Established Series Rev. GB 03/2013 MANVEL SERIES The Manvel series consists of very deep, well drained soils that formed in alluvium derived from soft limestone and shale. Manvel soils are on fans, plains, and interfluves. Slopes range from 0 to 15 percent. The mean annual precipitation is about 305 mm (12 inches) and the mean annual temperature is about 11 degrees C. (52 degrees F.). TAXONOMIC CLASS: Fine -silty, mixed, superactive, mesic Ustic Haplocalcids TYPICAL PEDON: Manvel silt loam, grassland. (Colors are for dry soil unless otherwise noted). A --O to 18 centimeters (0 to 7 inches); brown (IOYR 5/3) silt loam, brown (IOYR 4/3), moist; weak fine granular structure; soft, friable, nonsticky and nonplastic; common fine and very fine roots; strongly effervescent, 5 percent calcium carbonate equivalent; slightly alkaline (pH 7.6); clear smooth boundary (8 to 18 cm (3 to 7 inches) thick). Bk1--18 to 64 centimeters (7 to 25 inches); pale brown (1OYR 6/3) silt loam, yellowish brown (IOYR 5/4) moist; moderate medium subangular blocky structure; moderately hard, friable, slightly sticky and slightly plastic; common fine and very fine roots; 2 percent medium distinct irregular carbonate masses in matrix; violently effervescent, 20 percent calcium carbonate equivalent; moderately alkaline (pH 8.2); clear smooth boundary. (20 to 51 cm (8 to 20 inches) thick) Bk2--64 to 124 centimeters 25 to 49 inches; pale brown (IOYR 6/3) silt loam, yellowish brown (IOYR 5/4), moist; moderate fine prismatic structure; moderately hard, friable, slightly sticky and slightly plastic; few very fine roots; 8 percent medium distinct irregular carbonate masses in matrix; violent effervescence, 13 percent calcium carbonate equivalent; moderately alkaline (pH 8.2); gradual wavy boundary. (48 to 76 cm (19 to 30 inches) thick) Bk3--124 to 200 centimeters (49 to 79 inches); very pale brown (IOYR 7/4) silt loam, brownish yellow (10YR 6/6), moist; weak coarse subangular blocky structure; moderately hard, friable, slightly sticky and slightly plastic; 2 percent fine distinct irregular carbonate masses in matrix; violent effervescence, 35 percent calcium carbonate equivalent; moderately alkaline (pH 8.4).
