Map Unit Description(Brief,Generated)---Prowers County,Colorado West Farm Pit <br /> The Las, saline component makes up 90 percent of the map unit. Slopes are 0 to <br /> 1 percent. This component is on terraces, flood plains. The parent material <br /> consists of clayey alluvium from irrigation water over calcareous sandy alluvium. <br /> Depth to a root restrictive layer is greater than 60 inches. The natural drainage <br /> class is poorly drained. Water movement in the most restrictive layer is <br /> moderately low. Available water to a depth of 60 inches (or restricted depth) is <br /> moderate. Shrink-swell potential is moderate. This soil is occasionally flooded. It <br /> is not ponded. A seasonal zone of water saturation is at 24 inches during March, <br /> April, May, June, July, August, September, October. Organic matter content in the <br /> surface horizon is about 1 percent. This component is in the R067BY035CO Salt <br /> Meadow ecological site. Nonirrigated land capability classification is 4c. Irrigated <br /> land capability classification is 4s. This soil meets hydric criteria. The calcium <br /> carbonate equivalent within 40 inches, typically, does not exceed 10 percent. The <br /> soil has a moderately saline horizon within 30 inches of the soil surface. The soil <br /> has a maximum sodium adsorption ratio of 3 within 30 inches of the soil surface. <br /> Component: Haverson (5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Haverson soil is a minor component. <br /> Component: Las Animas (5%) <br /> Generated brief soil descriptions are created for major soil components. The Las <br /> Animas soil is a minor component. <br /> Map Unit: Ln—Las clay loam, sand substratum <br /> Component: Las, sand substratum (90%) <br /> The Las, sand substratum component makes up 90 percent of the map unit. <br /> Slopes are 0 to 1 percent. This component is on terraces, flood plains. The <br /> parent material consists of clayey alluvium from irrigation water over calcareous <br /> sandy alluvium. Depth to a root restrictive layer is greater than 60 inches. The <br /> natural drainage class is moderately well drained. Water movement in the most <br /> restrictive layer is moderately high.Available water to a depth of 60 inches (or <br /> restricted depth) is low. Shrink-swell potential is low. This soil is occasionally <br /> flooded. It is not ponded. A seasonal zone of water saturation is at 30 inches <br /> during March, April, May, June. Organic matter content in the surface horizon is <br /> about 1 percent. This component is in the R067BY035CO Salt Meadow <br /> ecological site. Nonirrigated land capability classification is 4w. Irrigated land <br /> capability classification is 3w. This soil does not meet hydric criteria. The calcium <br /> carbonate equivalent within 40 inches, typically, does not exceed 10 percent. The <br /> soil has a very slightly saline horizon within 30 inches of the soil surface. The soil <br /> has a maximum sodium adsorption ratio of 1 within 30 inches of the soil surface. <br /> Component: Glenberg (5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Glenberg soil is a minor component. <br /> Natural Resources Web Soil Survey 8/15/2018 <br /> Conservation Service National Cooperative Soil Survey Page 4 of 7 <br />
