Slopes are 3 to 5 percent. This component is on interfluves,plains. The <br /> parent material consists of loess.Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is well drained. <br /> Water movement in the most restrictive layer is moderately low. Available water to a depth of 60 inches(or restricted depth)is high. <br /> Shrink-swell potential is moderate. This soil is not flooded.It is not ponded. There is no zone of water saturation within a depth of 72 <br /> inches. Organic matter content in the surface horizon is about 2 percent. This component is in the R067BY002CO Loamy Plains <br /> ecological site. Nonirrigated land capability classification is 6e. Irrigated land capability classification is 6e. This soil does not meet hydric <br /> criteria. The calcium carbonate equivalent within 40 inches, typically,does not exceed 9 percent. There are no saline horizons within 30 <br /> inches of the soil surface. The soil has a maximum sodium adsorption ratio of 5 within 30 inches of the soil surface. <br /> Map unit: Bk-Bankard sand,0 to 1 percent slopes,moist,frequently flooded <br /> Component: Bankard,frequently flooded(90%) <br /> The Bankard,frequently flooded component makes up 90 percent of the map unit.
