Site Type: Rangeland <br />MLRA: 67B -Central High Plains, Southern Paz[ <br />Representative Soil Features <br />Sandy Bottomland <br />R067BY031C0 <br />The soils of this site are very deep, somewhat excessive to well drained, and moderately rapid to <br />rapidly permeable. These soils occur on flood plains and flood-plain steps. They formed in alluvium <br />derived from mixed sources. They typically are frequently flooded. Some soils have gravel at depths <br />of 10 to 60 inches. The available water capacity is typically low to moderate. The soil surface layer is <br />typically 3 to 8 inches thick and is loamy sand, sandy loam, and fine sandy loam. The soil moisture <br />regime is ustic aridic. The soil temperature regime is mesic. <br />The Historic Climax Plant Community (HCPC) should exhibit slight to no evidence of rills. Water flow <br />paths, if any, are broken, irregular in appearance or discontinuous with numerous debris dams or <br />vegetative barriers. Wind scoured areas are inherent to this site and some soil movement may be <br />noticeable on various landscape positions. Minor plant pedestalling may occur in these areas. <br />Overall, the soil surface is stable and intact. Sub-surface soil layers are non-restrictive to water <br />movement and root penetration. <br />These soils are susceptible to wind and water erosion where vegetative cover is inadequate. <br />Major soil series correlated to this ecological site include: Bankard and Glenberg <br />Other soil series that have been correlated to this site include: none <br />Parent Material Kind: alluvium <br />Parent Material Origin: mixed <br />Surface Texture: loamy sand, sandy loam, fine sandy loam <br />Surface Texture Modifier: none <br />Subsurface Texture Group: sandy <br />Surface Fragments 5 3" (% Cover): 0 <br />Surface Fragments > 3" (%Cover): 0 <br />Subsurface Fragments <_ 3" (% Volume): 0 <br />Subsurface Fragments > 3" (% Volume): 25 <br />Minimum Maximum <br />Drainage Class: well somewhat excessive <br />Permeability Class: moderately rapid rapid <br />Depth (inches): 80 80 <br />Electrical Conductivity (mmhos/cm)*: 0 2 <br />Sodium Absorption Ratio*: 0 0 <br />Soil Reaction (1:1 Water)*: 7.4 8.4 <br />Available Water Capacity (inches)*: 3 7 <br />Calcium Carbonate Equivalent (percent)`: 0 15 <br />*These attributes represent 0-40 inches in depth or to the first restrictive layer. <br />Technica] Guide USDA NRCS <br />Section IIE 3 Rev. 3/04 <br />
