The A horizon has hue of 10YR to 5YR, value 3 to 5 and 2 or 3 moist, and chroma of 2 or 3. Texture is sandy loam, fine sandy loam, loamy sand, or loamy fine sand. It is moderately acid to neutral. It contains 0 to 2 percent by volume of coarse fragments less than 76 mm in diameter.
The BA or AB horizon has hue of 10YR to 5YR, value 3 to 5 and 2 or 3 moist, and chroma of 2 or 3. Texture is sandy loam, fine sandy loam, or sandy clay loam. It is moderately acid to neutral.
The Bt horizon has hue of 2.5YR to 7.5YR, value of 4 to 6 and 3 to 5 moist, and chroma of 3 to 6. It is sandy clay loam, loam, or sandy loam and has 18 to 27 percent clay and more than 20 percent sand coarser than fine. This horizon ranges from slightly acid to moderately alkaline. Gravel ranges from 0 to 10 percent by volume. Some pedons have a few redoximorphic concentration masses of yellow or brown in the below 40 inches.
The BC horizon has hue of 2.5YR to 7.5YR, value of 4 to 6 and 3 to 6 moist, and chroma of 3 to 6. It is sandy clay loam, sandy loam or fine sandy loam with 8 to 27 percent clay. This horizon ranges from neutral to moderately alkaline. Coarse fragments less than 76 mm in diameter range from 0 to 10 percent by volume.
The C horizon has hue of 2.5YR to 7.5YR, value of 4 to 7 and 3 to 6 moist, and chroma of 4 to 8. It is coarse sandy loam, sandy loam, fine sandy loam, loamy sand or sand. This horizon ranges from slightly acid to moderately alkaline. Gravel ranges from 0 to 20 percent by volume.
COMPETING SERIES: These are the Carman, Chickasha, Milan, Navina, Ravia, Schulenburg, Stoneburg, Teval, Teller and Waynoka series in the same family. Carman soils have redoximorphic features at depths less than 20 inches. Chickasha and Stoneburg soils have bedrock at depths less than 60 inches. Milan soils have more clay in the argillic horizon. Navina soils have an argillic horizon with yellower hue. Ravia soils contain more than 10 percent coarse fragments in the argillic horizon. Schulenburg soils have sola more than 60 inches thick. Teval soils have a lower clay activity class. Teller soils contain less than 20 percent material coarser than fine sand in the argillic horizon. Waynoka soils have a lithologic discontinuity within 60 inches of the soil surface.
GEOGRAPHIC SETTING: Lovedale soils are on nearly level to strongly sloping hill slopes. The slope gradient ranges from 0 to 12 percent. The soils formed in old alluvium. The mean annual temperature ranges from 57 to 62 degrees F, and the mean annual precipitation ranges from 26 to 38 inches. Thornthwaite Annual PE Index ranges from 44 to 64. Frost free days range from 190 to 220. Elevation is 1000 to 1500 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Devol, Eda, Milan, Waynoka, and Wisby soils. Waynoka and Wisby soils are on slightly lower positions, in addition Waynoka soils have lithologic discontinuities and Wisby soils have gravelly substratum. The Devol and Eda soils have a less clayey subsoil and are on steeper slopes. Milan soils are on less sloping landscapes and have more clay in the argillic horizon.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is low or medium. Permeability is moderate.
USE AND VEGETATION: Most areas are cultivated. The principal crops are winter wheat and grain sorghum. Native vegetation is tall grasses.
DISTRIBUTION AND EXTENT: Central Rolling Red Prairies (MLRA-80A) of Oklahoma and Kansas. The soil is moderately extensive.
