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