Long-Term Soil Ecosystem Studies

This study investigates soil formation and carbon sequestration in an abandoned soil borrow pit. The borrow pit was excavated to provide material for Hwy 751 in the Duke Forest and abandoned in the 1930s. No attempts at remediation were made, so forest vegetation is successional. The new soil surface was in the C horizon, so all organic C and N can be assumed to be derived since the new primary successional ecosystem began to proliferate.
