Quantification of CO 2 evolution δ 13 C C3-Soil pH 4 -26.579 pH 8 -26.946 C4-Biochar BC350 -12.002 BC700 -12.291 Based on the different stable isotope composition (represented as δ 13 C value), the percentage of CO 2 -C from C4 plant can be known by determining the carbon isotopic composition after incorporation of new C4 vegetation C in C3 SOM pools.
