Map Unit Description(Brief,Generated)---Prowers County,Colorado West Farm Pit <br /> The Rocky Ford component makes up 90 percent of the map unit. Slopes are 1 <br /> to 3 percent. This component is on terraces, flood plains. The parent material <br /> consists of clayey alluvium from irrigation water over silty alluvium. Depth to a <br /> root restrictive layer is greater than 60 inches. The natural drainage class is well <br /> drained. Water movement in the most restrictive layer is moderately high. <br /> Available water to a depth of 60 inches (or restricted depth) is high. Shrink-swell <br /> potential is low. This soil is not flooded. It is not ponded. There is no zone of <br /> water saturation within a depth of 72 inches. Organic matter content in the <br /> surface horizon is about 1 percent. This component is in the R069XY006CO <br /> Loamy Plains, Lru's A& B 10-14 Inches, Rz. ecological site. Nonirrigated land <br /> capability classification is 4c. Irrigated land capability classification is 3e. This soil <br /> does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, <br /> typically, does not exceed 10 percent. There are no saline horizons within 30 <br /> inches of the soil surface. The soil has a maximum sodium adsorption ratio of 2 <br /> within 30 inches of the soil surface. <br /> Component: Kornman (5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Kornman soil is a minor component. <br /> Component: Numa(5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Numa soil is a minor component. <br /> Map Unit: RpA—Rocky Ford, clay substratum, 0 to 1 percent slopes <br /> Component: Rocky Ford, clay substratum (90%) <br /> The Rocky Ford, clay substratum component makes up 90 percent of the map <br /> unit.

Irrigated land <br /> capability classification is 3e. This soil does not meet hydric criteria. The calcium <br /> carbonate equivalent within 40 inches, typically, does not exceed 6 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: Numa(5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Numa soil is a minor component. <br /> usDA Natural Resources Web Soil Survey 8/15/2018 <br /> Conservation Service National Cooperative Soil Survey Page 6 of 7 <br />
