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 percent. This <br />component is on flood plains, terraces. The parent material consists of irrigation enriched clayey <br />alluvium over calcareous sandy alluvium. Depth to a root restrictive layer is greater than 60 <br />inches. The natural drainage class is somewhat poorly drained. Water movement in the most <br />restrictive layer is moderately high. Available water to a depth of 60 inches is high. Shrink-swell <br />potential is low. This soil is occasionally flooded. It is not ponded. A seasonal zone of water <br />saturation is at 30 inches during March, April, May, June. Organic matter content in the surface <br />horizon is about 1 percent. This component is in the R069XY03000 Salt Meadow ecological <br />site. Nonirrigated land capability classification is 4c. Irrigated land capability classification is 3e. <br />This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, <br />typically, does not exceed 10 percent. The soil has a slightly saline horizon within 30 inches of <br />the soil surface. <br />Component: Las Animas (5%) <br />The Las Animas component makes up 5 percent of the map unit. Slopes are 0 to 1 percent. The <br />parent material consists of sandy alluvium. Depth to a root restrictive layer is greater than 60 <br />inches. The natural drainage class is well drained. Available water to a depth of 60 inches is <br />very low. Shrink-swell potential is low. This soil is frequently flooded. It is not ponded. A <br />seasonal zone of water saturation is at 27 inches during May, June, July. This soil meets hydric <br />criteria. <br />Map Unit. Ld-Las clay loam, clay substratum <br />Component: Las, clay substratum (90%) <br />The Las, clay substratum 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 consists of irrigation <br />enriched clayey alluvium over sandy alluvium over clayey alluvium. Depth to a root restrictive <br />layer is greater than 60 inches. The natural drainage class is poorly drained. Water movement <br />in the most restrictive layer is moderately low. Available water to a depth of 60 inches is <br />moderate. Shrink-swell potential is moderate. This soil is occasionally flooded. It is not ponded. <br />A seasonal zone of water saturation is at 24 inches during March, April, May, June, July, <br />August, September, October. Organic matter content in the surface horizon is about 1 percent. <br />This component is in the R069XY03000 Salt Meadow ecological site. Nonirrigated land <br />capability classification is 4c. Irrigated land capability classification is 4s. This soil meets hydric <br />criteria. The calcium carbonate equivalent within 40 inches, typically, does not exceed 10 <br />percent. The soil has a moderately saline horizon within 30 inches of the soil surface. The soil <br />has a slightly sodic horizon within 30 inches of the soil surface. <br />Component: Las Animas (5%) <br />The Las Animas component makes up 5 percent of the map unit. Slopes are 0 to 1 percent. The <br />parent material consists of sandy alluvium. Depth to a root restrictive layer is greater than 60 <br />inches. The natural drainage class is well drained.
