Topographic & Soil Carbon Reconstructions in Agricultural Fields, Iowa
Hillslope transects at three sites showing redistribution of soil organic carbon (SOC) simulated over 160 years in Iowa. Sites (columns): Hoffman, Stinson, and Willis. Upper row shows hillshade maps illustrating topography at each site. Red lines show location of transects proceeding from upslope to downslope (e.g., A to A'). Lower three rows illustrate pattern of SOC along the transect distance (L) at soil depths at beginning of simulation (0 y), after 40 y, and at end of simulation (160 y). Red lines indicate the initial surface elevation at beginning of simulation. Insets highlight cases where soil with low SOC blankets soil with higher SOC.
