Abstract

Differences between 13C signatures in various types of organic matter and between ecosystems make up a strong tool in ecological studies. However, a thorough interpretation of 13C signatures requires sufficient knowledge on the factors that cause differences in 13C content. To examine how clay affects 13C fractionation, we studied biodegradation of maize leaves in microcosms either with sand alone, or sand mixed with the clay minerals kaolinite (15 or 20 %) or montmorillonite (20 %) and an inoculum of microorganisms isolated from soil during a 70-day experimental period.
