LOCATION MADALIN NY
The Madalin series consists of very deep, poorly drained soils on lake plains and depressions in the uplands. They formed in water-deposited materials. Saturated hydraulic conductivity is moderately low or moderately high to low throughout the soil. Slope ranges from 0 to 3 percent. Mean annual temperature is about 8 degrees C., and mean annual precipitation is about 995 mm.

COMPETING SERIES: There are no known competing series in the same family.
Monee soils are similar soils in related families. Covington soils have a weighted average of more than 60 percent clay (by weight) in the fine-earth fraction. Hoytville, Lorain, Miner, and Monee soils have episaturation. Lakemont soils have hues of 2.5YR through 7.5YR in the Btg horizons. Lakemont soils have hues of 2.5YR through 7.5YR in the Btg horizons.
GEOGRAPHIC SETTING: Madalin soils formed in glacial lake sediments, on lake plains and in depressions in the uplands. Slope ranges from 0 to 3 percent. Mean annual air temperature ranges from 5 to 10 degrees C; mean annual precipitation ranges from 790 to 1440 mm, and mean frost-free period ranges from 140 to 180 days. Elevation ranges from 70 to 550 m above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Rhinebeck soils. Arkport and Dunkirk soils formed in silty to fine sand deltaic deposits. Bath, Danley, Honeoye, Langford, Lansing, and Ontario soils formed in till. Howard and Palmyra soils formed in glacial outwash. Hudson soils formed in materials similar to that of Madalin soils but are moderately well drained. Rhinebeck soils formed in similar materials but are somewhat poorly drained. Fonda soils lack an argillic horizon and have more than 10 percent organic matter in the A horizon.
DRAINAGE AND PERMEABILITY: Poorly drained. The potential for surface runoff is negligible to very high. Saturated hydraulic conductivity is moderately low or moderately high in the surface and subsurface to moderately low or low in the subsoil and substratum.
USE AND VEGETATION: Cleared areas are used for growing hay and pasture. Some areas have been drained sufficiently to permit production of corn and small grains. Native vegetation is red maple, elm, white ash, hickory, oak, white cedar, hemlock, and white pine.
DISTRIBUTION AND EXTENT: The Erie and Ontario lake plains and the Ontario Lowlands of New Yorkl and the Mohawk and Hudson Valleys, and other larger valleys of the Allegheny Plateau in New York. MLRAs 101, 140, 142, and 144A. The series is moderately extensive.

REMARKS: This series was previously defined as poorly and very poorly drained. The very poorly was removed.
Diagnostic horizons and features recognized in the typical pedon (NASIS User Pedon ID 77NY073003) include:
1. Mollic subgroup - meets the requirements for mollic epipedon, except thickness, after mixing the upper 18cm where the Ap horizon is less than 25 cm thick and the lower boundary of the argillic horizon is below 75 cm.
2. Argillic horizon - from 20 to 84 cm (Btg1, Btg2, Btg3 horizons).
3. Endoaqualfs great group - Endosaturation from 20 cm (Btg1 horizon) to more than 200 cm.
4. Aquic moisture regime as evidenced by redoximorphic features in all layers between 25 cm and 40 cm, and within the upper 12.5 cm of the argillic horizon, more than 50% redox depletions with a chroma of 2 or less on faces of peds (reduced matrix in all subsurface horizons), and redox concentrations within peds.
