Scharpenseel, H.-W., Becker-Heidmann, P. (1994): 14C dates and 13C measures of different soil species. – In: Lal, R., Kimble, J. M., Levine, E. (Hg.): Soil processes and greenhouse effect, S. 72–89. USDA, Soil Conservation Service, National Soil Survey Center, Lincoln, NE

Abstract:

In this review depth profiles of 14C dates and 13C values of different soil types are compared and studied with emphasis on four major aspect:
1. Concept of „soil age“ versus SOM „residence time“; data base of soil carbon cycle related 14C dates; soil as a carbon source or sink
2. Efforts of maximum 14C dating in soil; SOM residence time clay interaction
3. Anthropogenic CO2/CH4 release and its effect on 14C dating and δ13C measurements
4. Carbon cycle and trace gas emission related indicator potential of 14C dating and δ13C measurement on soil material; approaches for sustained research
