TARRYTOWN SERIES
The Tarrytown series consists of deep, slowly permeable, loamy soils that formed in sandy and loamy marine deposits. Slopes are 0 to 2 percent.
TAXONOMIC CLASS: Fine-loamy, siliceous, superactive, hyperthermic Aquic Hapludalfs
TYPICAL PEDON: Tarrytown sandy clay loam, bouldery, cultivated. (Colors are for moist soil.)
Ap--0 to 7 inches; dark grayish brown (10YR 4/2) sandy clay loam; moderate medium subangular blocky structure; very friable; common fine soft white calcium carbonate nodules; many fine roots; mildly alkaline; clear wavy boundary. (2 to 8 inches thick)
Btk1--7 to 10 inches; dark yellowish brown (10YR 4/4) sandy clay loam; common fine faint yellowish brown mottles; moderate medium subangular blocky structure; friable; common fine soft white calcium carbonate nodules; thin continuous clay skins on ped faces; few fine roots; mildly alkaline; clear wavy boundary.
Btk2--10 to 14 inches; yellowish brown (10YR 5/4) sandy clay loam; common fine faint yellowish brown mottles; weak fine subangular blocky structure; friable; common fine soft white calcium carbonate nodules; sand grains bridged with clay; few fine roots; mildly alkaline; abrupt wavy boundary. (Combined thickness of the Bt horizons is 6 to 17 inches thick.)
Ck1--14 to 22 inches; mixed light gray (10YR 7/2) and light yellowish brown (10YR 6/4) clay loam; weak fine subangular blocky structure; very friable; many fine soft white calcium carbonate nodules; common fine shell fragments; mildly alkaline; gradual wavy boundary. (6 to 60 inches thick)
Ck2--22 to 50 inches; white (10YR 8/1) loam; weak fine subangular blocky structure; very friable; many fine soft white calcium carbonate nodules; common fine shell fragments; moderately alkaline; gradual wavy boundary. (0 to 30 inches thick)
C--50 to 80 inches; mixed light gray (10YR 7/2) and brownish yellow (10YR 6/6) fine sand; single grained; loose; common fine shell fragments; strongly alkaline.
TYPE LOCATION: Sumter County, Florida; 0.2 mile east of State Highway 301, 0.9 mile south of Main Street; SW1/4SE1/4 sec. 36, T. 19 S., R 22 E.
RANGE IN CHARACTERISTICS: Solum thickness is 12 to 20 inches. The soil is neutral to moderately alkaline throughout the solum and mildly to strongly alkaline in the C horizons. Boulders ranging in size from 10 inches to about 4 feet occur on the surface and in the solum. They occupy about 0.01 percent of the surface and solum and are estimated to occur at 150 to 200 foot intervals. Cobbles are on and within the soil at about the same percentage rate as the boulders. The A or Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 2 or 3. If value is 3 and chroma is 2, the A horizon is less than 6 inches thick. The texture is fine sandy loam or sandy clay loam.
The Btk horizon has hue of 10YR, value of 4 or 5, and chroma of 4 or 5, or value of 5 or 6, and chroma of 6 to 8, or hue of 7.5YR, value of 4, and chroma of 4. Few to common mottles in shades of brown and yellow are in most pedons. The texture is fine sandy loam or sandy clay loam. Some pedons have thin horizons of sandy clay.
The Ck horizon has hue of 10YR, value of 7 or 8 and chroma of 1 or 2. In some pedons the upper part is mixed low and high chroma colors in hue of 10YR, value of 6 to 8, and chroma of 1 to 6. Few to common mottles in shades of yellow are in some pedons. Texture is fine sandy loam, loam, or clay loam.
The C horizon has mixed colors in hue of 10YR, value of 6 or 7, and chroma of 2 to 6. Texture is sand or fine sand.
COMPETING SERIES: This is the
Aripeka series in the same family. Aripeka soils have sandy surface horizons and have bedrock within 40 inches.
GEOGRAPHIC SETTING: Tarrytown soils are on nearly level areas that are slightly higher than adjacent depressions. Slopes are less than 2 percent. The mean annual temperature is above 72 degrees F., the mean annual rainfall is about 56 inches.
GEOGRAPHICALLY ASSOCIATED SOILS:
Paisley soil is the most common associated soil. Paisley soil has a higher water table, an albic horizon and a solum that is greater than 20 inches thick.
DRAINAGE AND PERMEABILITY: Tarrytown soils are somewhat poorly drained. The high water table is within a depth of 18 to 30 inches for 1 to 3 months. Permeability is slow.
USE AND VEGETATION: Most of the acreage is in pasture and the natural vegetation consists of live oak, water oak, elm, and cabbage palms.
DISTRIBUTION AND EXTENT: Central Florida. The series is of small extent.

SERIES ESTABLISHED: Sumter County, Florida; 1985.
REMARKS: Hapludalfs occur in mesic and thermic temperature regimes, Soil Taxonomy page 129. This soil is hyperthermic. This soil lacks low chroma mottles in the argillic horizon, but due to a high water table its behavior is like that of the Aquic subgroup.
