Radiocarbon dating pedogenic carbonates
In addition to soil fertility, SIC plays an important regulatory ecosystem service by sequestering atmospheric COSoil inorganic carbon (e.g., various types of carbonates) can be lithogenic or pedogenic in origin [25,26].
While lithogenic carbonates are considered rock derived, pedogenic carbonates can form as a result of dissolution and re-precipitation of lithogenic or newly formed carbonates .
The presence of soil carbonates (disseminated and concretions) can also impact the C ages of carbonates that were younger than the ages of deposits in which they formed .
All sampled soils were classified as Fine-silty, mixed, frigid Pachic Hapludolls (Haplic Chernozem).
