Fig. 3. (A) Relationships of bulk and particle density of soil with SOC (soil organic carbon) concentration for the 0- to 10-cm depth and (B) depth distribution of bulk density under moldboard plow (MP), no-till with no beef cattle manure (NT), no-till with beef cattle manure (NTm), pasture, and forest long-term management practices at the Northern Appalachian Experimental Watershed in Coshocton County, OH. The LSD bars at a given soil depth indicate the significance of bulk density among the five management practices.
