Effect of Vegetation on the Morphology of Windsor Soils, Litchfield, Connecticut¹

ABSTRACT

Eastern hemlock (Tsuga canadensis) on outwash sand in Litchfield County, Connecticut produced a more acid forest floor and throughfall with a greater capacity to mobilize Fe than American beech (Fagus grandifolia) or white pine (Pinus strobus). White pine produced the least acid forest floor, and throughfall with the least capacity to mobilize Fe. These characteristics were reflected in the order of A2 and Bhir horizon thicknesses which was hemlock > beech > pine.
