EBBETS SERIES

The Ebbets series consists of very deep, well drained soils formed in a thick mantle (greater than 100 centimeters) of loamy human transported material with more than 10 percent human artifacts. They occur in anthropogenically altered landscapes in and near major urbanized areas of the Northeast. Saturated hydraulic conductivity is moderately high or high in areas where the soil cap has not been compacted, but is only moderately high where it has been compacted. Slope ranges from 0 to 60 percent. Mean annual temperature is about 12 degrees C and mean annual precipitation is about 1190 mm.

TAXONOMIC CLASS: Coarse-loamy, mixed, active, mesic Typic Eutrudepts

TYPICAL PEDON: Ebbets sandy loam on a nearly level fill plain. (Colors are for moist soil.)

^A --- 0 to 10 cm; very dark grayish brown (10YR 3/2) sandy loam; weak medium granular structure; friable; common very fine roots, common fine roots and many medium roots; slightly acid (pH 6.3); clear smooth boundary. (5 to 18 cm thick.)

^BA --- 10 to 17 cm; brown (10YR 4/3) gravelly sandy loam; weak medium subangular blocky structure parting to weak fine granular structure; friable; moderately few medium roots and moderately few fine roots; 15 percent gravel-sized rock fragments; moderately acid (pH 5.8); clear wavy boundary. (0 to 10 cm thick.)

^Bw1 --- 17 to 31 cm; dark yellowish brown (10YR 4/4) sandy loam; weak coarse subangular blocky structure; friable; moderately few very fine roots and moderately few fine roots; 5 percent gravel; slightly acid (pH 6.3); clear smooth boundary.

^Bwu2 --- 31 to 53 cm; dark yellowish brown (10YR 4/4) gravelly sandy loam; weak coarse subangular blocky structure; friable; moderately few fine roots; 5 percent stone-sized concrete, 2 percent cobble-sized concrete fragments, 13 percent gravel, and 2 percent gravel-sized concrete fragments; slightly alkaline (pH 7.4); clear smooth boundary.

^Bw3 --- 53 to 69 cm; 65 percent brown (10YR 4/3) and 35 percent dark yellowish brown (10YR 4/6) sandy loam; moderate coarse subangular blocky structure; friable; very few very fine roots; 10 percent (few) discontinuous distinct dark brown (10YR 3/3) organic stains; 5 percent gravel; neutral (pH 7.1); abrupt smooth boundary. (Combined thickness of Bw horizons is 15 to 60 cm)

2^Cu1 --- 69 to 90 cm; very dark grayish brown (10YR 3/2) very artifactual loamy sand; massive; friable; common very fine roots; 10 percent stone-sized concrete fragments, 30 percent cobble-sized concrete fragments, 7 percent gravel-sized concrete fragments, and 4 percent gravel; very slightly effervescent; slightly alkaline (pH 7.7); clear smooth boundary.

2^Cu2 --- 90 to 183 cm; brown (10YR 4/3) very artifactual loamy coarse sand; massive; friable; 10 percent stone-sized concrete fragments, 8 percent cobble-sized concrete fragments, 10 percent gravel-sized concrete fragments, 6 percent gravel, 5 percent gravel-sized asphalt fragments, and 3 percent gravel-sized coal slag fragments; very slightly effervescent; moderately alkaline (pH 8.0).

TYPE LOCATION: Queens County, New York: Kissena Corridor Park. USGS Jamaica, NY, topographic quadrangle: Latitude 40 degrees, 44 minutes, 58.89 seconds N. and Longitude 73 degrees, 49 minutes, 27.37 seconds W., NAD 1983.

RANGE IN CHARACTERISTICS: Thickness of the fill materials is greater than 100 cm. Coarse fragments range from 0 to 60 percent, with a weighted average of less than 35 percent in the control section. The weighted average of human artifacts exceeds 10 percent in the control section. Textures are commonly sandy loam, loam or silt loam but may include loamy sand or sand. Reaction ranges from strongly acid to moderately alkaline. Free carbonates derived from artifactual materials are found within 100 cm.

The ^A or ^Ap horizon has hue of 2.5Y through 2.5YR, value of 2 through 4, and chroma of 1 through 3. Structure is granular or subangular blocky with very friable or friable consistence, although compacted areas may have platy structure and/or firm consistence.

The ^Bw horizons have hue of 2.5Y through 2.5YR, value of 3 through 6, and chroma of 2 through 8. Structure is commonly subangular blocky with friable consistence, although compacted areas may have platy structure and/or firm consistence.

The ^C horizons have hue of 2.5Y through 2.5YR, value 3 through 6, and chroma of 1 through 8. Structure is commonly massive with friable to firm consistence. Some pedons may have plate-like divisions.

Natural horizons may occur under the human transported material. Their properties are similar to comparable natural soils of the region.

COMPETING SERIES: These are the Dover and Pequea series. Dover soils are formed in calcareous till deposits. Pequea soils formed in calcareous residuum.

GEOGRAPHIC SETTING: Ebbets soils are on nearly level to steeply sloping anthropogenically created or modified landforms. These soils formed in human transported materials greater than 100 cm thick, with more than 10 percent human artifacts. Slope ranges from 0 to 60 percent. Mean annual precipitation ranges from 1000 to 1250 mm. Mean annual temperature ranges from 8 to 17 degrees C.

GEOGRAPHICALLY ASSOCIATED SOILS: Laguardia, Centralpark, Foresthills (T), and Greenbelt soils are also found on anthropogenically altered landscapes. Laguardia and Centralpark soils have greater than 35 percent coarse fragments in the control section; Foresthills (T) and Greenbelt soils have less than 10 percent artifacts in the control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. Saturated hydraulic conductivity is moderately high or high in areas where the soil cap has not been compacted, but is only moderately high where it has been compacted.

USE AND VEGETATION: These soils are generally covered by turfgrass if part of a recreation area; overgrown with common weeds and grasses, raspberry, ragweed, and mugwort if stone-sized fragments appear on the surface; or may be wooded. Common trees include black locust, tree of heaven, black cherry, and boxelder.

DISTRIBUTION AND EXTENT: These soils occur on modified landscapes in and near major urbanized areas of the Northeast in MLRAs 144A and 149B. The soils of this series are small in total extent, but they are an important component of open space in urban areas.
