Figure 1.
Changes in CH4 flux with time (A) and total CH4 fluxes (B) under different manure application during rice cultivation.
Bars represent standard errors (n = 3). Different letters indicate significant difference (One-way ANOVA, p<0.05).

Soil properties and rice growth characteristics at harvesting.
Figure 2.
Changes in DOC concentration with time (A) and numbers of total mcrA gene copies (B) in soils incorporated with different manures.
Bars represent standard errors (n = 3). Different letters at the same stage indicate significant difference (One-way ANOVA, p<0.05).

Analysis of methanogen community composition by mcrA based T-RFLP under different manure application during rice cultivation.
The number indicated Shannon diversity index (H).
