Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

Creator:

Keiluweit, Marco

Abstract:

Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...

Are oxygen limitations under recognized regulators of organic carbon turnover in upland soils?

Creator:

Keiluweit, Marco, Nico, Peter S., Kleber, Markus, and Fendorf, Scott

Abstract:

Understanding the processes controlling organic matter (OM) stocks in upland soils, and the ability to management them, is crucial for maintaining soil fertility and carbon (C) storage as well as projecting change with time. OM inputs are balanced by the mineralization (oxidation) rate, with the difference determining whether the system...
