Interpretive Summary:

Technical Abstract: Five management systems: continuous corn (CC), cropland to woodland (CW), cropland to pastures (CP), no-till (NT), and conservation reserve program (CRP), were selected to evaluate their long-term impacts (5, 10 and 15 yr) on soil C sequestration. Nine soil cores from each system were randomly collected at 0¿10 cm depth and were analyzed for various C pools. Total C content varied in response to management systems and management systems x time interactions. Averaged across years, soils under NT had significantly higher total C content than soils under CW, CRP, CP and CC, respectively. The active C content varied significantly in response to management systems, and time x management interactions. Humic and fulvic acid C content changed in response to management systems over time. The total and active C stocks increased but non-humic, humic and fulvic acid C stocks decreased in NT soils than other soils. Results suggest that soils under conservation management practices especially NT have sequestered C over time than soils under CC.
