Figure 5

(a) MAOC content resistant to chemical oxidation with 6% NaOCl (MAOCremain) in relation to the Fed to aluminous clay ratio. (b) Cumulative OC mineralization after 50 days of incubation in relation to the Fed to aluminous clay ratio. (c) MAOCremain content related to the cumulative OC mineralization. Aluminous clay represents the weight sum of kaolinite and gibbsite present in the < 2-µm fraction and Fed denotes the content of total pedogenic Fe extractable by dithionite-citrate-bicarbonate. All regression models are provided in Table S6.
