Eva soil and landscape
Soil profile: The Eva series consists of very deep, somewhat excessively drained, moderately rapid permeable soils. (Soil Survey of Stevens County, Kansas; by Thomas C. Byrd, Natural Resources Conservation Service)
Landscape: Sunflowers in an area of Eva loamy fine sand, 1 to 3 percent slopes, on the south side of the Cimarron River in Stevens County.
Eva soils formed in sandy eolian deposits of Holocene age. These soils are on very gently to strongly sloping dunes and plains of the Southern High Plains, northern part (MLRA 77A). Slope ranges from 1 to 9 percent. Mean annual air temperature is about 13 degrees C (57 degrees F), and mean annual precipitation is about 460 mm (18 in).
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, mesic Aridic Haplustalfs
Solum thickness: more than 203 cm (80 in)
Thickness of the ochric epipedon: 8 to 48 cm (3 to 19 in)
Thickness of the argillic horizon: 25 to 180 cm (10 to 71 in)
Depth to secondary calcium carbonate: 152 to 203 cm (60 to 80 in)
Depth to lithologic discontinuity (where present): 120 to 185 cm (47 to 73 in)
Particle-size control section (weighted average):
Silicate clay: 8 to 16 percent
USE AND VEGETATION: These soils are mainly used for rangeland. Some areas are used for irrigated crops. Native vegetation is dominantly sand bluestem little bluestem, sideoats grama, sand lovegrass, sand paspalum, fall witchgrass, and sand dropseed. Sand sagebrush is the major woody species with lesser amounts of skunkbush sumac and yucca.
DISTRIBUTION AND EXTENT: Southwest Kansas and Southeastern Colorado south of the Cimarron River, and the Oklahoma Panhandle (MLRA-77A in LRR H). This soil is moderately extensive. These soils were formerly included in the Vona series.
