Abstract

This study focused on soil carbon (organic and inorganic) and silicon pools across a soil toposequence encompassing all landscape positions (summit, shoulder, backslope, footslope, and toeslope), and for the soil profile. A soil toposequence, derived from till parent material with an un-drained closed depression, was selected in central Ohio. Pedons were collected from the Gahanna Woods Park. All soil samples were analyzed for selected physical and chemical properties. It is highlighted that the un-drained closed depression enhances the soil organic carbon (SOC) accumulation across the integrated toposequence, in particular at the lower landscape positions (footslope and toeslope), and it favors the formation of desired soil structure (granular). Soil total N was correlated with that of SOC across the toposequence and within pedons
