Abstract
The four soils, developed in compact, reddish brown, sandstone-derived till, ranged from well to poorly drained. Eluviation of clay and sesquioxides had occurred in all of the soils as indicated by their light gray, acid Ae horizons that were depleted of clay, Fe, Al, and Mn, However, only the two better drained soils, Tignish and O'Leary, had the B horizon of accumulation of amorphous organic matter-Fe, -Al complexes that is diagnostic of Podzolic soils. Weakly expressed horizons of clay accumulation occurred in all of the soils and they were somewhat more developed in the more poorly drained soils. Subsoils of all four soils had low hydraulic conductivities, high bulk densities, and a mixed clay mineralogy consisting of mica, chlorite, kaolinite, and expansible minerals. The properties of the four soils were closely similar to those of reddish brown soils of similar texture and drainage class from Nova Scotia. Two were classified as Bisequa Grey Luvisols and the others as Gleyed Gray Luvisol and Low Humic Eiuviated Gleysol.
