The soil microbial community is critically important in plant nutrition and health. However, this extremely sensitive to various environmental conditions. A pot experiment was conducted during the wheat seedling stage better understand influences of coupled application nitrogen (N) decomposing inoculants (MDI) on bacteria under different water regimes. There were two levels six fertilization. results reveal that stress increased relative abundance Acidobacteria decreased Firmicutes Proteobacteria. 250 kg N ha−1 altered diversity bacterial but nitrifying bacteria. Nitrous oxide (N2O) carbon dioxide (CO2) emissions negatively correlated with Myxococcota Methylomirabilota while positively Patescibacteria. These gases also bacteria, correlation more significant full irrigation regime. findings indicate MDI does not substantially influence its relationship greenhouse gas emission at would mainly depend rational control amount applied.
