Moston muck - on a slope of less than 1 percent in a cultivated field. Fibers are derived primarily from herbaceous plants, although some pedons contain less than 15 percent by volume twigs and small wood fragments. Depth to the underlying sand ranges from 21 to 51 inches. Reaction ranges from very strongly acid to neutral. The Oa horizon has hue of 7.5YR, 10YR or is neutral, value of 2 to 3, and chroma of 0 to 3.
Reaction ranges from very strongly acid to neutral.
The Lco horizon has hue of 10YR to 5Y, value of 2 to 5, and chroma of 1 to 3. It is coprogenous silt loam or coprogenous silty clay loam. Reaction ranges from moderately acid to slightly alkaline and free carbonates are present in some pedons. The Lco horizon has slightly plastic consistence and shrinks upon drying to form hard clods that are difficult to re-wet. The Cg horizon has hue of 10YR or 2.5Y, value of 3 to 6, and chroma of 1 or 2.
