Microknolls make up 5 to 25 percent of the pedon. Typically, colors in the microknoll have value of 4 or more. Calcium carbonate concretions, mainly in clusters, range from 1 to 5 percent in the lower part of the microknoll in some pedons. The A horizon has hue of 10YR to 5Y, value of 3, and chroma of 1. In rice culture Ap horizons 4 to 6 inches thick include value that ranges to 4.
Reaction ranges from extremely acid to very strongly acid.
The Bss horizon has hue of 10YR to 5Y, value of 3 or 4, and chroma of 2 or less. Iron accumulations range from few to common with colors in shades of brown or yellow. Some pedons contain a few redoximorphic features in shades of red or gray. Redoximorphic features in the upper part are developed or enhanced by rice culture. Reaction is very strongly acid or strongly acid.
