Abstract

Abstract

Moderately well to very poorly drained soils in parts of the North Carolina Coastal Plain have subsurface horizons with the physical properties of fragipans. The brittle parts of the fragipan horizons are dense gray loamy sands, sandy loams or silt loams. This dense brittle material occurs in the same horizon with less dense, friable, more clayey materials.

Soils with weakly expressed fragipan horizons have an A, Bt, Bt & A′2x, B′tx, and C horizon sequence. Soils with the most strongly expressed fragipan horizons have an A, B, A′2x, B′tx, and C or an A, A2x, Btx, and C horizon sequence. The fragipan horizon in the most strongly expressed pans in places engulfs the overlying B horizon.
