Carbon Dynamics in Vertisols as Revealed by High-Resolution Sampling
Two Vertisol soil profiles under xeric soil moisture regimes, located at Qedma and Akko, Israel, were investigated and compared to a profile under ustic moisture regime, located in Hyderabad, India. Samples were taken in complete successive 2 cm thin layers down to about 180 cm depth or more. Organic and inorganic carbon were analyzed with regard to 13 C and 14 C concentrations. While all soils have radiocarbon ages of several thousand years BP, …

We report here the remainder of the Hamburg University dates on thin soil layers (HAM 1652–3129)
The Use of Natural 14 C and 13 C in Soils for Studies on Global Climate Change
Some examples are given to show that the depth distribution curves of natural 14 C and 13 C of thin-layer sampled soil profiles can be used for inferring changes in soil organic matter and climate changes. By using a simple exchange model, we can determine whether decomposition products are fixed by clay or transported downward toward the groundwater table. We can also estimate the amount of the Greenhouse gases, CO 2 and CH 4 , produced by the d…
Shifts in 14C Patterns of Soil Profiles Due to Bomb Carbon, Including Effects of Morphogenetic and Turbation Processes
Principles contributing to changes and the final balance of rejuvenation in 14 C dates of soil profiles are identified. The annual addition to the atmosphere of ca 5.5·10 12 kg of dead carbon from fossil carbon sources and 1.5·10 12 kg of older carbon from forest clearing make soil appear older. Bomb carbon and annual recycling of most of the 115·10 12 kg of terrestrial organic carbon, equivalent to the annual photosynthetic turnover of carbon, r…
Thin Layer δ 13 C and D 14 C Monitoring of “Lessive” Soil Profiles
The natural 14 C and 13 C content of soil organic matter and their dependence on depth for two Alfisols are presented. This soil type which covers a large area of the earth's surface is characterized by clay migration processes (“Lessivé”). The samples were taken as successive horizontal layers of 2cm depth from an area of ca lm 2 size as deep as the C content allows 14 C analysis. The minima of the D 14 C distribution decrease with depth, while …
