In the original article, there was a mistake in Table 4 as published. Inadvertently, a misordered data table was used for calculating SOC (Soil Organic Carbon) pool results for Table 4. The numerical values were slightly erroneous and some of the letters referring to statistically significant differences in each comparison of SOC pools were incorrect. The corrected Table 4 is shown below.

TABLE 4

TABLE 4. Test results of the fixed main effects in the generalized linear mixed models for soil carbon pools in soil.

Consequently, a correction has been made to Results, sub-section ‘Soil Organic Carbon and Microbial Biomass Carbon in the Soil Profile.' The corrected third paragraph is shown below.

The total amounts of SOC and C_mic on the topsoil layer were calculated based on both fixed 0–20 cm depth and on the equivalent soil mass method (equivalent mineral soil mass of 200 kg m⁻², ≈15 cm depth; Wendt and Hauser, 2013; Singh et al., 2015) which takes soil bulk density into account (Table 4). Plowed treatment contained statistically significantly less SOC (6.37 kg C m⁻²) on 20 cm depth compared to the reduced tillage and no-till treatments (6.76 and 7.08 kg C m⁻²; p < 0.01, respectively). The difference turned to non-significant with the equivalent soil mass results between plow and reduced tillage (5.24, 5.29, and 5.54 kg C m⁻² on plow, reduced tillage and no-till treatments, respectively). Crop rotation did not change SOC in tillage treatments (Table 4). Mean C_mic of the treatment combinations ranged from 65.3 and 77.0 g C_mic m⁻² in the soil layer equivalent to 200 kg m⁻² (Table 4), which is about 1.1–1.4% of the total soil C stock.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
