KUSHAQUA SERIES


The Kushaqua series consists of very deep, somewhat poorly drained soils formed in sandy deposits on lake plains and outwash plains. Saturated hydraulic conductivity ranges from moderately low to moderately high in the ortstein layer, and high to very high throughout the remainder of the pedon. Slope ranges from 0 to 3 percent. Mean annual precipitation is about 1016 millimeters and mean annual temperature is about 6 degrees C.

RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 50 through 115 centimeters. Rock fragments, mainly gravel, range from 0 through 5 percent by volume above 100 centimeters, and 0 through 20 percent below. Depth to the ortstein material ranges from 12 through 50 centimeters from the mineral surface. Redoximorphic features occur within a depth of 50 centimeters and may be masked by ortstein colors.

The O horizon has hue of 2.5YR through 10YR, value of 2 through 3, and chroma of 1 or 2. It consists of slightly through highly decomposed plant material. Reaction is extremely acid or very strongly acid.

Some pedons have A horizons up to 3 inches thick with hue of 5YR through 10YR, value of 2 through 3, and chroma of 1 or 2. Texture is sand, fine sand, loamy sand, or loamy fine sand. Reaction of the A horizon ranges from extremely acid through strongly acid.

Some pedons are currently or were previously under cultivation and contain an Ap horizon up to 20 centimeters thick with hue of 5YR through 10YR, value of 2 through 3, and chroma of 1 through 3.

COMPETING SERIES: There are no series in the same family.

The Finch, Spot, Mcivor, and Whittemore soils are in a related family. These soils have a lower mean annual precipitation and are outside of Region R.

GEOGRAPHIC SETTING: Kushaqua soils are on lake plains and outwash plains. Slope ranges from 0 to 3 percent. Mean annual precipitation is 890 through 1270 centimeters. Mean annual temperature ranges from 3 degrees to 7 degrees C. Mean annual frost-free days ranges from 70 to 160 days. Elevation ranges from 60 through 900 meters above sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Wolf Pond (T), Onchiota (T), Adams, Colton, Searsport, Burnt Vly, and Monadnock soils. The well drained Wolf Pond (T) and Onchiota (T) soils are on slightly higher landform positions and form a drainage sequence with the Kushaqua soils. The very poorly drained Searsport soils are on lower landscape positions. Adams and Colton soils do not contain more than 50 percent ortstein or redoximorphic features and are on higher landscape positions. The organic Burnt Vly soils are in adjacent depressions and drainageways. The Monadnock soils are formed in till and have a higher content of rock fragments.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The potential for surface runoff is negligible to very high. Saturated hydraulic conductivity ranges from moderately low to moderately high in the ortstein layer, and high to very high throughout the remainder of the pedon.

USE AND VEGETATION: Kushaqua soils are almost entirely in second growth woodland and support stands of balsam fir, red spruce, eastern white pine, red maple, and yellow birch.

DISTRIBUTION AND EXTENT: Adirondack Mountains of northern New York. MLRA 143. The series is of small extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.

REMARKS: The series is named after nearby Lake Kushaqua, in the Town of Franklin, Franklin County, NY.

Diagnostic horizons and features recognized in this pedon are:
Albic horizon - the zone from 12 to 30 centimeters (E1 and E2 horizons);
Spodic horizon - the zone from 30 to 46 centimeters (Bh and Bhsm horizons);
