TYPE LOCATION: Charleston County, South Carolina; 1.0 mile east of SC 165 on SC 162 in Hollywood; 1.35 miles south on S-10-79 (Gibson Road); 0.1 mile south of S-10-1846 (Church Flats Road); 1300 feet west of road; 30 feet south of ditch.
RANGE IN CHARACTERISTICS: Solum thickness is 40 to more than 72 inches. The A and E horizons are very strongly acid to mildly alkaline. The upper part of the B horizon is strongly acid to moderately alkaline and the lower part of the B horizon is slightly acid to moderately alkaline.
The Ap horizon has a hue of 10YR or 2.5Y or is neutral, value of 3 or 4, and chroma of 0 to 2. The A horizon, if present, has a hue of 10YR or is neutral, value of 2 or 3, and chroma of 0 to 2 and is as much as 5 inches thick. The E horizon has a hue of 10YR, value of 5 through 8, and chroma of 1 or 2. It commonly has masses of iron accumulation with colors of higher chroma. The A and E horizons are loamy fine sand or fine sandy loam.
The Btg horizon has hue of 10YR to 5GY, or neutral, value of 4 to 7, and chroma of 0 to 2. Few to many masses of iron accumulation in colors ranging to hue of 2.5YR and chroma of 6 are in most pedons. The particle size control section has 18 to 35 percent clay. The texture is dominantly sandy clay loam or clay loam but ranges from sandy loam to sandy clay.
The BCg horizon has colors similar to the B horizon. Texture is fine sandy loam, sandy loam or sandy clay loam.
Some pedons have a C horizon with colors and reaction similar to the B horizon and with textures ranging from sandy to clayey.
COMPETING SERIES: The Tuckerman series is the only known series in the same family. Tuckerman soils are moderately acid to very strongly acid throughout the profile. Argent, Cherokee, Clodine, Fork, Grifton, Gourdin, Lightning, Meggett, Okeetee, Sorter, and Wadmalaw series are similar series in other families. Argent, Cherokee, and Meggett soils have an abrupt textural change between the A and B horizons and more than 35 percent clay in the Bt horizon. Clodine and Sorter soils have less than 18 percent clay in the Bt horizon. Fork and Okeetee soils have dominant chroma of 3 or more between the A or Ap horizon and a depth of 30 inches. Grifton and Gourdin soils have siliceous mineralogy. Lightning soils have more than 35 percent clay in the Bt horizon. Wadmalaw soils have an umbric epipedon.
GEOGRAPHIC SETTING: Yonges soils are on nearly level areas of the lower Coastal Plains from 5 to 25 feet above sea level. The soils formed in loamy sediments. Average annual rainfall is about 49 inches. Freeze-free growing season averages 280 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Argent, Meggett, Okeetee, and Wadmalaw series plus the Charleston, Edisto, Hockley, Kiawah, Santee, Seabrook, and Stono series. Charleston soils have 10 to 18 percent clay in the particle size control section. Edisto soils have a fragipan and less than 18 percent clay in the particle size control section. Hockley soils are better drained and have matrix colors of higher chroma in the argillic horizon. Kiawah and Seabrook soils are sandy throughout. Santee and Stono soils have surface layers more than 10 inches thick with color values of 2 or 3 and Santee soils have more than 35 percent clay in the particle size control section.
DRAINAGE AND PERMEABILITY: Poorly drained; very slow runoff; moderately slow permeability. Water table is within 10 inches of the surface for about 6 months during most years. Some areas in narrow drainageways commonly flood.
USE AND VEGETATION: Most of the area is in forests of sweetgum, loblolly pine, water oak, live oak, willow oak, and minor species such as holly and blackgum with undergrowth of shrubs and vines. Cleared and drained areas are used for cabbage, Irish potatoes, soybeans, corn, and pasture.
DISTRIBUTION AND EXTENT: Atlantic Coastal Plain in South Carolina, Alabama, Florida, and North Carolina and possibly Georgia. The series is of moderate extent.
