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