Dwight soil series
Profile of a Dwight soil. Dwight soils are very clayey and have a high shrink-swell potential and exchangeable sodium content. These properties limit the availability of water to plants. Note the cracks in the photo that extend to a depth of 40 centimeters. (Soil Survey of Tallgrass Prairie National Preserve, Kansas United States Department of Agriculture, Natural Resources Conservation Service, and United States Department of the Interior, National Park Service)
The Dwight series consists of deep, moderately well drained soils that formed in residuum derived from limestone and shale. Dwight soils are on closed depressions on hillslopes on uplands in the Bluestem Hills, MLRA 76. Slopes range from 0 to 3 percent. Mean annual precipitation is 840 millimeters (33 inches), and mean annual temperature is 13 degrees C (55 degrees F), at the type location.
TAXONOMIC CLASS: Fine, smectitic, mesic Typic Natrustolls
Soil moisture regime: ustic moisture regime bordering on udic
Soil temperature regime: mesic
Mollic epipedon thickness: 35 to 100 centimeters (14 to 40 inches)
Depth to argillic: 10 to 20 centimeters (4 to 8 inches)
Depth to secondary carbonates: 33 centimeters (13 inches) or greater
Depth to Natric horizon: 10 to 20 centimeters (4 to 8 inches)
Depth to limestone or shale: 100 centimeters to 150 centimeters (40 to 60 inches)
Mean annual soil temperature: 13 to 14 degrees C (55 to 58 degrees F)
Soil moisture: The soil moisture control section is intermittently moist in some part from March through October; driest in November through February
Particle size control section (weighted average)
Clay content: 40 to 60 percent
Sand content: 1 to 20 percent
USE AND VEGETATION: Used for native range. Native vegetation is mid and tall prairie grasses.
DISTRIBUTION AND EXTENT: Eastern Kansas and northeast Oklahoma; Land Resource Region H Central Great Plains Winter Wheat and Range Region; Major Land Resource Area 76 Bluestem Hills; Major Land Resource Area 74 Central Kansas Sandstone Hills; Land Resource Region M Central Feed Grains and Livestock Region; Major Land Resource Area 112 Cherokee Prairies. This series is of large extent.
