TYPE LOCATION: Located on the Tuscarora Nation, Niagara County, New York, 2800 feet south west of the junction of Printup and Mount Hope Roads.
RANGE IN CHARACTERISTICS: Solum thickness and depth to bedrock ranges from 20 to 40 inches. Depth to carbonates range from 20 to 40 inches within the soil, or the underlying bedrock is effervescent. Rock fragments range from 2 to 20 percent in the solum, and from 15 to 35 percent in the substratum if present.
The Ap or A horizon has hue of 5YR through 10YR. Values of 2 or 3; and chroma of 1 or 2. Texture ranges from silt loam to silty clay. Reaction ranges from moderately acid through neutral.
The E horizon, where present, has hue of 2.5YR through 7.5YR, value of 5 through 7 and chroma of 1 through 3
The Bt horizons have hues of 2.5YR through 7.5YR, values of 4 or 5 and chroma of 2 or 3 in the upper part and 2 through 4 in the lower part. Texture ranges from silt loam to silty clay. Reaction ranges from slightly acid to slightly alkaline.
The BC horizon and C horizon, where present, has hues of 2.5YR through 7.5YR, values of 3 through 6 and chroma of 3 or 4. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Angola, Appleton, Burdett, Darien, Haskins, Lamberjack, and Ovid, series. The Angola soils are yellower hues in the lower subsoil and substratum. Appleton, Burdett, Darien, Haskens, Lamberjack and Ovid are greater than 40 inches to bedrock.
GEOGRAPHIC SETTING: Nuhi soils formed from till deposits on the planar or slightly concave surfaces of paleozoic age cuestas or bedrock controlled till plains. Slope ranges from 0 to 8 percent. Mean annual air temperature ranges from 46 degrees to 50 degrees F., mean annual precipitation ranges from 30 to 40 inches, and the mean frost-free period ranges from 140 to 170 days. Elevation ranges from 300 to 800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Churchville, Lockport, Hilton, Rhinebeck, Uwihreh, and Yunenyeti. The Churchville, Lockport, Rhinebeck and the Uwihreh soils have more clay in the family control section. The Yunenyeti soils have no layer above 20 inches that is dominated by color of chroma less than 2. The Hilton soils are deep to bedrock.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is low to very high. Permeability is moderate or moderately slow in the solum and moderate to slow in the substratum.
USE AND VEGETATION: Cleared areas are used for growing small grains, hay and pasture management. Some areas are in juvenile stages of forest succession. Native vegetation is red maple, hickory, black walnut, ash and white oak.
DISTRIBUTION AND EXTENT: The Erie and Ontario Lake plains of New York. MLRA 101. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.
