The land capability classifications are 1 (irrigated) and 6e (non-irrigated). This component is in the R069XY006C0 Loamy ecological site description. Map Unit: RfB -Rocky Ford silty clay loam (Found in the East Pitj The Rocky Ford silty clay loam component makes up 90 percent of the map unit. It occurs in the elevation range of 4,300 feet to 5,000 feet. The frost free period is 145 to 175 days. Slopes are 1 to 3 percent. This component is formed on terraces on silty alluvium. Atypical soil profile is 0 to 12 inches silty clay loam, 12 to 60 inches silt loam. Runoff is slow and the erosion hazard is slight. Depth to a root restrictive layer is greater than 80 inches. The natural drainage class is well drained. The capacity of the most limiting layer to transmit water is moderately high (0.20 to 0.60 in/hr.) The depth to seasonal high water table is more than 80 inches. The frequency of flooding is none and the frequency of ponding is none. The permeability is moderate and the available water capacity is high (about 9.9 inches). The sodium adsorption ration was not provided in the dataset. The maximum content of calcium carbonate is 15 per cent. The soil alkaline was not provided in the dataset. Soil gH ranges from7.9 to 8.4. It has a moderate shrink-swell potential. The soil is non-saline (0.0 to 2.0 mmhoslcm). The soil is suited to irrigated crops. The native flora was not provided in the dataset. The land capability classifications are 2e {irrigated) and be (non-irrigated). This component is in the R069XY006C0 Loamy ecological site description. Map Unit: Rg -Rocky silty caly loam, wet (Found in the East and West Pits) The Rocky Ford silty clay loam component makes up 90 percent of the map unit. It occurs in the elevation range of 4,300 feet to 5,000 feet. The frost free period is 145 to 175 days. Slopes are 0 to 1 percent. This component is formed on nearly level low terraces of the Arkansas River. A typical soil profile is 0 to 12 inches silty clay loam with stratified subsoil. Runoff is stow and the erosion hazard is slight Depth to a root restrictive layer is greater than 80 inches. The natural drainage class is somewhat poorly drained. The capacity of the most limiting layer to transmit water is moderately high (0.20 to 0.60 in/hr.) The depth to seasonal high water table is 36 to 60 inches. The frequency of flooding is none and the frequency of ponding is none. The permeability is moderate and the available water capacity is high (about 9.9 inches). The sodium adsorption ration was not provided in the dataset. The maximum content of calcium carbonate is 10 per cent. The soil alkaline was not provided in the dataset. Soil pH was not provided in the dataset. The soil's shrink-swell potential was not provided in the dataset. The soil isnon-saline to slightly saline (2.0 to 8.0 mmhos/cm). The soil is suited to irrigated crops. The native flora was not provided the dataset. The land capability classifications are 2w (irrigated) and 6w (non- imigated). This component is in the R069XY030C0 Salt Meadow ecological site description.
