It is silt loam, loam, or clay loam and very strongly acid to neutral. The 2Bt horizon has hue of 5YR to 2.5Y, value of 4 to 6, and chroma of 4 to 8 in the upper part and value of 5 or 6 and chroma of 2 to 8 in the lower part and in the 2BC and 2C horizons. There are 5YR or redder hues within the upper part of the argillic horizon as either matrix color or mottles. Texture of the 2Bt and 2BC horizons is clay loam or clay. The upper 20 inches of the argillic horizon averages 36 to 48 percent clay and more than 20 percent sand.
Reaction is very strongly acid to neutral.
The 2C horizon is clay loam, loam or silty clay loam with more than 15 percent sand. Reaction is slightly acid to mildly alkaline. These are the Kilkenny and Ladoga soils. Kilkenny soils do not have 5YR hue in the upper part of the argillic horizon. Ladoga soils have less than 5 percent sand throughout the solum and have less red colors in the upper part of the argillic horizon.
