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.

The Morphology of Burnt Dirt: A pedologic investigation of fire history across ecosystems

There's a lot of interest around fires effects on soil. What's less often discussed is how well the soil records fire by the presense of Pyrogenic Carbon (PyC). We used the NEON sites and quantified how much PyC was present, and its relative quality, down soil profiles often reaching 1-meter in depth. Turns out, fire *was* everywhere.

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!)

Responses in soil following intensive biomass and compaction treatments in the Oregon Cascades

I hope you enjoy my Masters Defense. It was a labor of love.
