This poorly drained soil is primarily located in broad flatwoods in irregular area shapes ranging from 5 to 500 acres in size. The organic matter content and fertility of the soil is low.〔Belz, David J., Lewis J. Carter, David A. Dearstyne, and John D. Overing. Soil Survey of Hendry County, Florida. N.p.: USDA, IFAS, 1990.
