Figure 1: 13C abundances (δ13C; %) of leaching solution of sterilised soil with and without 13CO2 addition, and the amount (ml) of the corresponding leaching solution.
From: Abiotic carbonate dissolution traps carbon in a semiarid desert

Blue columns and the blue dash line refer to sterilised soil with 13CO2 addition. Red columns and the red dash line refer to sterilised soil without 13CO2 addition. Error bars represent standard error of the mean.
