Understanding the effects of tillage practices on wheat straw decomposition and shaping associated microbial communities is essential for enhancing microbial-mediated breakdown and optimizing residue management to enhance soil health, nutrient cycling, and sustainability in agricultural systems. In this study, the effect of different tillage practices on wheat straw decomposition and associated bacterial and fungal community compositions during non-growing and growing seasons were studied. To simulate tillage, litter bags filled with wheat straw were placed at respective soil depths for conventional (22–24 cm) and reduced (8–10 cm) tillage, and on the surface for the no-tillage treatment. The subsets of the litter bags were randomly retrieved after 145 days and at the end of the experiment after 290 days. Statistical analysis revealed that tillage treatments significantly influenced the decomposition rate and nutrient release over time. Overall, the alpha diversity of the decomposition-associated microbial community was not substantially affected by different tillage treatments, while beta diversity exhibited distinct microbial community compositions in relation to tillage practices.

Bacterial communities expressing diverse functions highly fluctuated in the first and second week after planting, and these fluctuations diminished progressively after the third week. Bacteria capable of biocontrol stabilized after the fourth week, while those involved in nutrient cycling continued to change in abundance week-to-week. Thus, bacterial specialization may be concomitant with bacteriome stabilization. With N fertilizer application, bacteria with diverse functions continued to fluctuate through the fifth week. However, regardless of fertilization, bacterial communities stabilized by the sixth week. It may take two weeks for roots to select for soil bacteria to assemble a specific rhizosphere bacteriome, but when N is applied, this period extends.

Using a greenhouse microcosm experiment, we compared soils from a 20-year eucalypt plantation (Euc) and secondary vegetation (Sec) covers, cultivated for five months with <i>Eucalyptus grandis</i>, <i>E. globulus</i>, or left uncultivated. We measured plant growth, P and N concentrations, root and soil enzyme potential activities, and soil properties. Results showed that <i>E. globulus</i> plants in Euc soil had 23% higher shoot biomass production and 27% greater P uptake efficiency compared to plants in Sec soil. Both eucalypt species showed improved P and N use efficiencies in Euc soils, suggesting beneficial soil legacy effects. Furthermore, microbial traits related to arbuscular mycorrhizal (AM) fungi persisted partially in Sec soils, suggesting a beneficial AM fungal legacy for new eucalypt cultivation. The potential activity of enzymes associated with soil carbon and sulfur cycles was clearly influenced by plant presence, whereas enzymes related to the P cycle maintained their potential activity regardless of plant presence, indicating a lasting soil legacy for P mineralization enzymes.

Therefore, we compared the microbial C use efficiency (CUE), biomass turnover rate (rB), microbial biomass C (MBC) and necromass C (MNC) across soil profiles from middle and old-aged forest and evaluated how these microbial traits are related to SOC storage. The results revealed that both forests could accumulate SOC and old-aged forest supported higher SOC storage than middle-aged forest from 2005 to 2020. Moreover, SOC was concentrated on the surface soils of middle-aged forest, whereas it was more distributed across the deeper soil profile in old-aged forest.

Random forest analysis suggested that SOC accumulation is controlled mainly by microbial physiological traits rather than other factors including environmental variables. Specifically, microbial CUE and turnover rates increased in old-aged forest, resulting in higher MBC and MNC contents, which in turn led to SOC accumulation. Moreover, the effects of plant and soil properties on SOC storage are regulated mainly by microbial-physiological parameters and the size of microbial C pools.
