Abstract
Black carbon (BC) or charcoal is thought to represent an important component of the carbon cycle, but has seldom been quantified in soils. We quantified soil BC in a temperate mixed-grass savanna in the southern Great Plains using benzenecarboxylic acids as molecular markers for BC. Soils were collected from four fire treatments (repeated summer fires in 1992 and 1994; repeated winter fires in 1991, 1993 and 1995;

Mollisols are known to contain stable, black humus components which originate from
charred or coal-derived particles. As such black carbon (BC) significantly affects soil
fertility and interferes with models on soil organic matter dynamics, an accurate prediction of BC input into soils and an elucidation of the mechanisms of BC turnover
is essential. The main aims of this study were (i) to identify the sources of BC in the
