The functional consequences of the irrigation treatment on the amino of the irrigation treatments on the amino acids. a shows the irrigation effect on the amino acids profile through an NMDS. Individual samples are resembled with filled circles. Amino acid vectors were overlaid, where only significantly correlated amino acids (p < 0.05) shown. Vectors pointing to the left direction along the first axis are enriched in the irrigation samples, whereas vectors pointing to the right side are enriched in the non-irrigated samples. b Integrates the amino acid profile and nifH OTU cluster abundances. The figure shows both the bacteria (circles) and the amino acid (square) where the color would be green if they are enriched in the irrigated treatment or red when enriched in the non-irrigated treatment. Gray links indicate a positive co-occurrence whereas a purple link indicates a negative co-occurrence
