MICROMORPHOLOGICAL CHARACTERISTICS OF AN ONEIDA SOIL PROFILE

Abstract
The macro- and micromorphological characteristics of an Oneida soil profile are reported, together with the results of chemical and hydrological determinations. The data indicate that porosity decreased with depth m this profile, that clay migration was a dominant process, and that dithionite- and oxalate-extractable iron distribution was similar to that reported for Gray-Brown Podzolic soils. An electron microprobe analysis of a dark, thin-section feature in the Bt1 horizon showed it to contain 5–10% Fe, varying amounts of aluminum, low levels of manganese, and traces of phosphorus.
