Description

The Acuna series consists of deep, well drained, moderately permeable soils that formed in calcareous, silty, sediments from limestone hills. These soils are on filled valley and stream terraces, and have slopes ranging from 0 to 3 percent. Mean annual temperature is 70 degrees F., and mean annual precipitation is 18 inches. TAXONOMIC CLASS: Fine-silty, carbonatic, hyperthermic Aridic Calciustolls TYPICAL PEDON: Acuna silty clay--rangeland. (Colors are for dry soil unless otherwise stated.) A1--0 to 18 inches; dark grayish brown (10YR 4/2) silty clay, very dark grayish brown (10YR 3/2) moist; the upper 2 inches is grayish brown (10YR 5/2); moderate medium subangular blocky structure parting to moderate medium granular; slightly hard, friable; common fine and medium roots; common fine pores; few fine threads and films of calcium carbonate; few fine calcium carbonate concretions less than 2 mm across; calcareous; moderately alkaline; clear wavy boundary. (10 to 20 inches thick) B21--18 to 30 inches; brown (7.5YR 5/4) clay, dark brown (7.5YR 4/4) moist; moderate medium subangular blocky structure parting to moderate medium granular; hard, friable; few fine roots; common very fine pores; few films and threads of calcium carbonate; few thin discontinuous clay films on vertical ped surfaces; calcareous; moderately alkaline; abrupt wavy boundary. (6 to 28 inches thick) B22ca--30 to 38 inches; pink (7.5R 7/4) silty clay, brown (7.5YR 5/4) moist; weak fine subangular blocky structure; slightly hard; friable; many very fine pores; 15 percent by volume of threads, films, and concretions 2 mm to 2 cm across of calcium carbonate; calcareous; moderately alkaline; clear wavy boundary. (8 to 28 inches thick) B23ca--38 to 60 inches; pink (7.5YR 8/4) silty clay, reddish yellow (7.5YR 7/6) moist; weak fine subangular blocky structure; slightly hard, friable; common very fine pores; 8 percent by volume of threads, films and soft masses of 2 mm to 2 cm across of calcium carbonate, calcareous; moderately alkaline; gradual wavy boundary. (10 to 25 inches thick) B24ca--60 to 72 inches; reddish yellow (7.5YR 6/6) silty clay, strong brown (7.5YR 5/6) moist; weak fine subangular blocky structure; slightly hard, friable; about 5 percent by volume of soft masses and concretions 2 mm to 2 cm across of calcium carbonate; calcareous; moderately alkaline.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to more than 60 inches. The depth to distinct accumulations of calcium carbonate is about 16 to 40 inches with 5 to 30 percent visible secondary forms. Total calcium carbonate content in the 10 to 40 inch control section is about 40 to 55 percent. Depth to limestone or gravel ranges from 6 to 20 feet. Limestone fragments of pebble size range from 0 to 15 percent. COLE ranges from 0.03 to 0.05.
