Genesis, Morphology, and Classification of Mounded Soils in Eastern Oklahoma¹

ABSTRACT

Numerous small mounds are unique features of landscapes that extend from the southern part of Missouri to the coast of Texas. Many hectares of eastern Oklahoma are included in this vast area. The mounds occur in densities of 8 to 16/ha.

These mounds were studied with special emphasis on the genesis, morphology, and classification of associated soil pedons. Laboratory measurements included particle size distributions, bulk density, extractable cations, and organic matter extractions.

Soil morphological features and laboratory analyses indicated that the development of the mounded soils differs from that of the associated intermound pedons by being highly altered by the many organisms of the landscape that assemble in the selected elevated soil to escape seasonal wet soil conditions.

Mounded soils of Site I are classified as Aquic Paleudolls or Aquic Argiudolls in the present system of soil classification (12). But most of the mounded soils which were studied would be better classified with a vermic modifier.
