The authors regret that in the above article three errors were published:
1. In Table 1, column 2, line 9, ‘spring rape’should not be underlined.
2. In Section 2.2, line 7, 250
◦C should be 520
◦C.
3. In Fig. 2 legend, symbols for measured values in low- and high-OM treatments should be interchanged.
The corrected versions are given below and overleaf.
Section 2.2 Biomass C (line 7)
