Root decomposition and carbon storage in soil organic matter.

​We combined root decomposition techniques with soil fractionation techniques to quantify the transfer of carbon and nitrogen from decomposing fine-root litter to relatively long-lived SOM using the unique depleted C-13 signature of organic material in plants and soils enriched with elevated [CO2]. ​​
