Figure 4

Changes in the relative abundances of bacterial genera across the N gradients in the wheat (A) and soybean (B) seasons. Only shown are those classes correlated with N added (Spearman’s r-values). Bars indicate one standard deviation. Asterisks show significant correlations (**P < 0.01, *P < 0.05). sCK, sN1 and sN2 indicate different N treatments in the soybean season; wCK, wN1 and wN2 indicate different N treatments in the wheat season.
