Response to Comment on 'Soil carbon persistence governed by plant input and mineral protection at regional and global scales'.

ABSTRACT

We demonstrated that ignoring the non-linear relationship between topsoil Δ14 C and plant carbon (C) input in Wu et al.'s analysis was the fundamental reason for the discrepancy between their analysis and ours. By considering such a non-linear relationship, plant C input still predominantly governs the topsoil C turnover.
