Extraction methods used:

Total Carbon (tC): by dry combustion (DUMAS)

Total Inorganic Carbon (tiC): Acidification with 4M phosphoric acid, analysed on Auto-Calcis

Total Organic Carbon (toC) = total Carbon minus inorganic Carbon

Total Nitrogen (tN): by dry combustion (DUMAS)

Carbon to Nitrogen Ratio (C:N Ratio): Total Carbon divided by total Nitrogen

Active Carbon: Oxidation of permanganate
