      abstract     = {Fertilization affects soil microbial community by altering
                      soil organic carbon (C) and nutrients availability. However,
                      it remains unclear how changes in stoichiometric C, N, and P
                      ratios resulting from fertilization affect microbial
                      community. We investigated a 26-year field experiment
                      receiving inorganic fertilizers (N, NP, PK, and NPK),
                      organic N combination (with manure and straw), natural
                      recovery (fallow), and no fertilizer (control). The aim of
                      this study was to explore the responses of microbial
                      community to C: N:P stoichiometry in soil and microbial
                      biomass of topsoil (0–20 cm) and subsoil (20–40 cm).
                      Results showed that compared to control treatment, organic
                      application increased the ratio of fungi to bacteria (F:B)
                      in topsoil and gram-negative bacteria to gram-positive
                      bacteria (G−:G+) in subsoil. However, application of
                      inorganic decreased both the F: B and G−:G+ ratio in
                      topsoil. Increasing soil C, N and P availability resulted
                      from inorganic fertilizers and organic combination
                      fertilization caused stoichiometric imbalance between soil
                      and microbial biomass. As a result, the F:B and G−:G+
                      ratio were positively related to C:N imbalance but
                      negatively associated with N:P imbalance in topsoil.
                      Redundancy analysis (RDA) showed that main factors
                      regulating microbial community were pH, C:P and N:P
                      imbalances in topsoil, whereas TDN, N:P imbalance, DOC and
                      soil C:N in subsoil. Furthermore, C:P and N:P imbalance
                      explained $16.4\%$ in topsoil, and N:P imbalance explained
                      $22.0\%$ in subsoil of microbial community variation. These
                      results reveal the shifts of soil microbial community are
                      driven by changes in soil pH and C, N and P stoichiometric
                      imbalance from long-term fertilization.},
