“…Paul et al (2018) reported that land use patterns influenced the soil microbial community structure, mainly by changing soil properties. Sun et al (2016) also found that soil parent material determined soil bacterial community structure, where the variation of soil properties was the main reason. That may be because the larger variation in soil properties masks the role of land use pattern, soil parent material, and sampling location.…”

Phosphorus (P) deficiency is an important factor that limits the agricultural production potential in acidic soils. The bacterial phoC gene encodes non-specific acid phosphatase (ACP), which participates in the mineralization of soil organic P and is therefore important for the improvement of soil P availability. However, the function and community population of phoC-harboring bacteria and their driving factors in acidic soil remain largely unknown. For this study, 51 soil samples and 207 plant samples were collected from four locations in the acidic soil region of southern China. Quantitative PCR and high-throughput sequencing were employed to analyze abundance and community composition of phoC-harboring bacteria. The results showed that soil P availability was the important nutrient element limiting the growth of both plants and soil bacteria. Soil ACP activity was clearly higher than alkaline phosphatase, indicating the important effect of phoC-harboring bacteria in acidic soils. ACP activity and phoC gene abundance showed a significant positive correlation, and both were closely related to soil available P, total carbon, and total nitrogen. The dominant genera of phoC-harboring bacteria involved Cupriavidus, Stenotrophomonas, and Xanthomonas. Compared to land-use pattern, sampling location, and soil parent material, soil property played a more important role in affecting phoC-harboring bacterial community structure, where N-related variables including soil NO3- -N, NH4+ -N, and C/N ratio appeared to be the main factors. These findings suggest that phoC-harboring bacteria should provide an important contribution to soil P availability in acidic soil, and its function and community composition were strongly associated with soil nutrients.

“…However, those methods can degrade soil through compaction and acidification, leading to crop yield reduction (Horrigan, Lawrence, & Walker, ). Use of chemical fertilizers has also decreased soil bacteria community richness and diversity and has significantly changed soil bacteria community structure (Ramirez, Craine, & Fierer, ; Sun et al, ). Similar to our results, Zhao, Jiang, et al (), in their eight‐consecutive‐year field experiment using the wheat–maize cropping system in northwest China, observed significantly higher crop yields in a combined straw and chemical fertilizer treatment than with no straw addition.…”

Soil organic carbon (SOC) is essential for soil fertility and climate change mitigation, and carbon can be sequestered in soil through proper soil management, including straw return. However, results of studies of long‐term straw return on SOC are contradictory and increasing SOC stocks in upland soils is challenging. This study of North China upland agricultural fields quantified the effects of several fertilizer and straw return treatments on SOC storage changes and crop yields, considering different cropping duration periods, soil types, and cropping systems to establish the relationships of SOC sequestration rates with initial SOC stocks and annual straw C inputs. Our meta‐analysis using long‐term field experiments showed that SOC stock responses to straw return were greater than that of mineral fertilizers alone. Black soils with higher initial SOC stocks also had lower SOC stock increases than did soils with lower initial SOC stocks (fluvo‐aquic and loessial soils) following applications of nitrogen‐phosphorous‐potassium (NPK) fertilizer and NPK+S (straw). Soil C stocks under the NPK and NPK+S treatments increased in the more‐than‐20‐year duration period, while significant SOC stock increases in the NP and NP+S treatment groups were limited to the 11‐ to 20‐year period. Annual crop productivity was higher in double‐cropped wheat and maize under all fertilization treatments, including control (no fertilization), than in the single‐crop systems (wheat or maize). Also, the annual soil sequestration rates and annual straw C inputs of the treatments with straw return (NP+S and NPK+S) were significantly positively related. Moreover, initial SOC stocks and SOC sequestration rates of those treatments were highly negatively correlated. Thus, long‐term straw return integrated with mineral fertilization in upland wheat and maize croplands leads to increased crop yields and SOC stocks. However, those effects of straw return are highly dependent on fertilizer management, cropping system, soil type, duration period, and the initial SOC content.

“…Proteobacteria have been putatively recognized as copiotrophic taxa (taxa that thrives in conditions of elevated C and N availability and exhibites relatively rapid growth rates) 34, 56, 58 and favores nutrient-rich conditions and associated with carbon rich regimes. In contrast, Acidobacteria is considered to be an oligotrophic taxon that exhibites relatively slow growth rate and ability to metabolize nutrient-poor substrates56 . The relative increase (25.5%) in Acidobacteria increased reported here is consistent with the BCC shifts under twenty-three years of nitrogen-containing inorganic fertilization applications 11 .…”
