This project will advance our understanding of soil processes that control the amount of carbon stored in soil. Understanding the controls on soil carbon storage and loss are critical for managing our natural environment for plant productivity, for improving our water quality, and for mitigating the effects of anthropogenic climate change. This project involves a series of experiments that will describe how fire and erosion impact the storage of carbon in soil, how it is chemically transformed over time, and how it may impact water quality. The results of this work will inform land managers in both urban and forested areas make management decisions to improve productivity, increase carbon storage, and improve water quality. The educational component of this project will make collected data publicly available for educators in teaching modules that can be freely used to teach about soil, water quality, and the natural environment. The aim of this research project is to determine the relative importance of burn severity, soil type, erosion, and time since fire as drivers of dissolved organic matter (DOM) and pyrogenic carbon (PyC) quality and quantity in soils and outflow water. This work will be achieved by (1) collecting intact soil cores from plots with differing burn severities and conducting simulated leaching experiments to quantify throughflow of PyC and DOM, (2) establishing sediment fences to describe the role of burn severity on sediment and the related DOM quality
