B, M and B × M means Two-way ANOVA result of Biochar, Manure and BM treatment, respectively. The Different lower-case letters represent significant differences among fertilization treatments, P < 0.05
The same is for Tables 3 and 4
* Test significant at the 5% level (P < 0.05)
** Test significant at the 1% level (P < 0.01); ns: test non-significant at the 5% level
