| Abstract: | δ
13C values of crop and forest soils were measured 8 years after disposal of paper sewage sludge. The carbon transfer from paper
sludge downward to the first humic layer is evidenced by a 13C-enrichnient of up to + 5.6‰ due to the input of 13C-enriched sludge carbonates. 13C/12C composition is thus a novel, sensitive parameter to follow the downward transfer of paper sludge carbon. |
