Bissett soil series

Profile of Bissett very gravelly loam in an area of Bissett-Rock outcrop complex, 20 to 70 percent slopes. Bissett soils contain more than 35 percent coarse fragments, and are shallow soils over limestone. (Soil Survey of Big Bend National Park, Texas; by James Gordon, Soil Scientist, James A. Douglass, Soil Scientist, and Dr. Lynn E. Loomis, Soil Scientist, Natural Resources Conservation Service)

 

The Bissett series consists of very shallow and shallow, well drained soils. They formed in colluvium and residuum weathered from limestone. These soils are on undulating to very steep hills and mountains. Slopes range from 1 to 70 percent.

 

TAXONOMIC CLASS: Loamy-skeletal, carbonatic, thermic Lithic Ustic Haplocalcids

 

Soil moisture: The soil is moist in some part of the epipedon for less than 90 cumulative days in most years. Ustic aridic moisture regime.

Soil temperature: 61 to 69 degrees F.

Depth bedrock: 6 to 20 inches

Calcium carbonate equivalent: 40 to 80 percent by volume

 

USE AND VEGETATION: Used for livestock grazing and wildlife habitat. The native plant community consists of sideoats grama, tanglehead, cane bluestem, green sprangletop, black grama, and plains bristlegrass.

 

DISTRIBUTION AND EXTENT: West Texas, Southern Arizona, and Southern New Mexico. MLRAs 42 and 38. The series is of moderate extent. These soils were formerly included in the Altuda series. The epipedon meets all requirements for a mollic epipedon except the soil is not moist for 3 months or more (cumulative) during the growing season.
