The soil moisture control section is moist for longer periods of time during the summer than the <br />winter.Soil Temperature: 48 to 59 degrees F.Depth to caldc horizon: 24 to 35 inches. <br />A horizon: <br />Hue: 10YR or 7.5YR <br />Value: 3 to 5 dry, 3 or 4 moist <br />Chroma: 2 to 4 <br />Texture: loam or day loam <br />Bw horizon: <br />• Hue: SYR, 7.5YR, or 10YR <br />Value: 4 to 6 dry, 3 to 5 moist <br />Chroma: 3 to 6 <br />Texture: loam or day loam <br />Bk horizon: <br />Hue: 5YR, 7.5YR, or 10YR <br />Value: 5 to 8 dry, 4 to 7 moist <br />Chroma: 3 to 5 <br />Texture: loam, silty Gay loam, Gay loam, or sandy day loam <br />Calcium carbonate: 15 to 50 percent with more than 5 percent visible carbonates. <br />COMPETING SERIES: These are the Abra (AZ), Bighams (AZ), Bowdish (CO), Copeman (WY), Creel (NM), <br />Harvey (NM), Hemandez (NM), Honlu (t1T), Numa (CO) and Pultney (CO) series. Abra soils do not have a Iambic <br />horizon and have a calcic horizon at a depth of less than 20 inches. Bighams, Bowdish, Creel, and Pulthey soils <br />have a lithic or paralithic contact at 20 to 40 inches. Copeman, Harvey, and Honlu soils have a calcic horizon at <br />a depth of less than 24 inches. Hemandez soils are 9 to 12 inches deep to the caldc horizon. Numa sots do not <br />have a Iambic horizon and in addition are moistfor longer periods in the spring.GEOGRAPHIC SETTING: Darvey <br />• (Revised March 2006) Attachment 2.04.9-3-18 <br />
