Roots to Regolith: Sources of organic matter across the National Ecological Observatory Network (NEON) soil plots

Finding carbon in soils is easy, tracing where it came from is hard and tracing that carbon *down* the soil profile is even harder. Here I presented some of my dissertation work where we examine plant derived carbon compounds across the NEON sites, and down soil profiles often reaching 1-meter or more in depth.

Does Root Carbon from Harvested Trees Replace Mineral Carbon? Effects of LTSP Treatments in a Western Oregon Douglas-fir Forest

Forest soils are can be resilient to harvesting, but what about two or three or four rotations worth of biomass removals? Here I present some work from my Masters, combining it with one chapter of my dissertation on the resilience of soil-C following harvesting (it's all the roots!)
