RANGE IN CHARACTERISTICS: The depth to the base of soil development ranges from 76 to 127 cm (30 to 50 inches). The depth to carbonates is 69 to 127 cm (27 to 50 inches). The depth to horizons with greater than 25 percent sand ranges from 38 to 76 cm (15 to 30 inches). The mollic epipedon ranges from 25 to 46 cm (10 to 18 inches) in thickness. The series control section ranges from moderately acid to neutral in the upper two parts of the series control section and from moderately acid to moderately alkaline in the lower two parts.
The upper part of the series control section (Ap, A, and/or AB horizon) has hue of 10YR, value of 2 or 3, and chroma of 1 to 3. It is silt loam.
The second part of the series control section (Bt horizon) has hue of 10YR and 7.5YR, value of 4 or 5, and chroma of 3 or 4. It is silty clay loam or silt loam. The clay content averages between 22 and 35 percent, and sand content averages between 5 and 20 percent.

COMPETING SERIES: These are the Atkinson, Burchard, Calmar, Cokato, Cresco, Cresent, Durand, Friesland, Griswold, Hitt, Jasper, Joslin, Keosauqua, Kishwaukee, Marbletown, Moingona, Morrill, Nuxmaruhanixete, Pana, Parmod, Penfield, Reedslake, Rockton, Schoolcraft, Shelby, Sibleyville, Velma, and Winnebago series. Atkinson, Calmar, Hitt, Marbletown, Rockton, and Sibleyville soils have a lithic or paralithic contact within a depth of 152 cm (60 inches). Burchard, Cokato, Cresco, Joslin, Parmod, Reedslake, Shelby, and Velma soils average more than 15 percent clay in the lower part of the series control section. Cresent, Kishwaukee, Nuxmaruhanixete, and Schoolcraft soils average more than 70 percent sand in the lower part of the series control section. Durand and Winnebago soils have hue as red as 5YR in some part the series control section. Friesland, Griswold, and Moingona soils average more than 25 percent sand in the second part of the series control section. Jasper and Penfield soils average less than 10 percent rock fragments in the lower part of the series control section. Keosauqua, Morrill, and Pana soils contain carbonates at depths greater than 127 cm (50 inches).
GEOGRAPHIC SETTING: Ringwood soils are on nearly level to sloping till plains. Slopes range from 0 to 12 percent. These soils formed in 38 to 76 cm (15 to 30 inches) of silty material and in the underlying loamy till. Mean annual air temperature ranges from 7 to 11 degrees C (45 to 52 degrees F), mean annual precipitation ranges from 737 to 1016 mm (29 to 40 inches), frost free days range from 140 to 180 days, and elevation ranges from 207 to 320 m (680 to 1050 feet) above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Drummer, Griswold, Elburn, Pella, and Plano soils. Drummer, Elburn, Pella, and Plano developed in loess or other silty material and in the underlying loamy outwash. The poorly drained Drummer and Pella soils and the somewhat poorly drained Elburn soils are on lower landform positions. The well drained Plano and Griswold soils are on similar landform positions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is low or medium. Saturated hydraulic conductivity is moderately high or high (4.23 to 42.33 micrometers per second) in the solum and high (14.11 to 42.33 micrometers per second) in the underlying material. Permeability is moderate to moderately rapid in the solum and moderately rapid in the underlying material.
USE AND VEGETATION: Most areas are cropped. Corn, soybeans, and small grain are the principal crops. Some areas are used for meadow. Native vegetation was prairie grasses.
DISTRIBUTION AND EXTENT: Northern Illinois and southern Wisconsin. The extent is moderate in MLRAs 95B, 105, 108A, 108B, and 110.
