Soils are moderately deep to deep, very dark colored, highly organic, poorly drained, and typically acid in reaction. • They range from sandy loam to clay in texture and include • pests and mucks. Peat has formed layers up to 6 inches thick at some locations. Cobbles are common, but depth is fairly _ effective. Soil moisture is plentiful throughout the growing season most years. Soils may become dry on the surface in some spots in late summer and fail or during unusually dry spells; other spots are nearly always wet. These soils are highly erodible when exposed following plant cover loss. b. Soils in this site are: - C 9$
