Massive carbon addition to an organic-rich Andosol increased the subsoil but not the topsoil carbon stock

Zieger, Antonia ; Klaus, Kaiser ; Ríos Guayasamín, Pedro ; Kaupenjohann, Martin (2018-05-07)

Andosols are among the most carbon-rich soils, with an average of 254 Mg ha−1 organic carbon (OC) in the upper 100 cm. A current theory proposes an upper limit for OC stocks independent of increasing carbon input, because of finite binding capacities of the soil mineral phase. We tested the possible limits in OC stocks for Andosols with already large OC concentrations and stocks (212 g kg−1 in ...
