Abstract Nitrogen (N) metabolism is a key metabolic pathway of nutrient cycling in forest ecosystems. However, the mechanisms by which mixed plantation litter improves microbial N transformation are poorly understood. Thus, we investigated characteristics, metabolism‐related genes, and modules soil three types forests: coniferous (CP forest), broadleaf (BP forests (MCBP forest). Results indicated that total (TN), hydrolysable organic (THON), percentage values NH 4 + ‐N/TN NO 3 − BP MCBP were higher than those CP litter, was attributed to increase abundance fixation genes dissimilatory nitrate reduction genes. The increased bacterial number diversity, taxa. Bacterial 1 2 identified, consisting Acidobacteria, Actinobacteria, Chloroflexi, Nitrospirae, Proteobacteria, Gemmatimonadetes, while archaeal module 5 also module, comprising Thaumarchaeota Euryarchaeota. Nutrients limiting factor decomposition further influencing enzymes. Therefore, during northern China.
