“…In the present study, soil microbial network complexity increased from corn land to grass land, forest and natural land, indicating that the lower network complexity of soil bacteria in corn land need additional management where nutrient-use efficiency is low and degradation of soil quality is serious, which accords with a recent study on KRD process in southwest China (Jiang et al, 2014). That is, disturbances such as cultivation and fertilization might eliminate certain functional soil bacteria (Neher, 1999;Huang et al, 2019). In contrast, soil microbial network complexity is much higher in natural land, though attainment of steady state equilibrium in natural ecosystems is rare (Neher, 1999).…”

Microorganisms play critical roles in belowground ecosystems, and karst rocky desertification (KRD) control affects edaphic properties and vegetation coverage. However, the relationship between KRD control and soil bacterial communities remains unclear. 16S rRNA gene next-generation sequencing was used to investigate soil bacterial community structure, composition, diversity, and co-occurrence network from five ecological types in KRD control area. Moreover, soil physical-chemical properties and soil stoichiometry characteristics of carbon, nitrogen and phosphorus were analyzed. Soil N and P co-limitation decreased in the contribution of the promotion of KRD control on edaphic properties. Though soil bacterial communities appeared strongly associated with soil pH, soil calcium, soil phosphorus and plant richness, the key factor to determine their compositions was the latter via changed edaphic properties. The co-occurrence network analysis indicated that soil bacterial network complexity in natural ecosystem was higher than that in additional management ecosystem. Candidatus Udaeobacter, Chthoniobacterales, and Pedosphaeraceae were recognized as the key taxa maintaining karst soil ecosystems in KRD control area. Our results indicate that natural recovery is the suitable way for restoration and rehabilitation of degraded ecosystems, and thus contribute to the ongoing endeavor to appraise the interactions among soil-plant ecological networks.

“…Changes in soil conditions can affect the composition and diversity of soil microbial communities (Qin, Yeboah, et al, 2017). Plastic film mulching has been demonstrated to change the soil hydrothermal and nutrient conditions, which in turn affects the composition and diversity fungal communities (Huang, Liu, Mou, Zhang, & Jia, 2019; Liu et al, 2012). However, our findings are consistent with those obtained by Liu et al (2012) who demonstrated that there was no significant difference in the richness of AM fungi between plastic film mulching and non‐mulching treatments (Figure 3c,d).…”

Plastic film mulching can affect soil organic carbon (C) lability in semiarid regions. Arbuscular mycorrhizal (AM) fungi represent an important route for plant‐derived C into soil and can be influenced by agricultural practices. Whether the changes of AM fungal community affect soil organic C sequestration is a fundamental question in semiarid environments. To this end, we conducted two field experiments investigating the influence of a Funneliformis mosseae inoculation and mycorrhizal‐suppression using benomyl application on maize growth, soil fractions of organic C, AM fungal parameters, including diversity profiling using the Illumina MiSeq. The results showed that AM fungal community composition was significantly altered by plastic film mulching and fungicide applications, soil organic C fractions and nitrogen were most important factors in influencing the AM fungal community. AM fungal inoculation significantly increased particulate organic C and light fraction organic C content, due to enhance dextramatrical hyphal length (EMH), glomalin content, and root biomass. Conversely, fungicide applications reduced labile organic C, possibly through decreasing EMH, glomalin content and soil AM fungal diversity. Increases in relative abundance of F. mosseae in rhizosphere soil, coupled with increases in AM fungal root colonization from F. mosseae inoculation indicates successfully established by outcompeting the existing natural AM fungal community. Plastic film mulching resulted in significant increases in maize yield and water use efficiency, and AM fungal inoculation was found to amplify the effects. Thus, AM fungal inoculation may act as an effective farming practice to improve soil organic C fractions, which can boost maize productivity.

“…Soil pH can play a decisive role in large‐scale soil bacterial communities (Mohammad et al, 2018; Shi et al, 2018), but given the close geographic distance among our test plots and relatively narrow range of pH (Maestre et al, 2015; Table 1), it is reasonable that pH had no significant effect on the soil bacterial community in our study (Table 1). Soil moisture was only affected by film mulch and had no significant effect on soil bacterial community; this may be due to other soil properties (TN, SOC, NH 4 + ‐N and NO 3 − ‐N) influencing the potential effects of soil moisture on the soil bacterial community (Huang et al, 2019).…”

“…Changes in physicochemical properties under plastic film mulch can indirectly drive changes in the microbial community (Farmer, Zhang, Jin, Zhang, & Wang, 2017; Qian et al, 2018) that affect the rhizosphere microbial community structure and metabolic function (Benitez, Osborne, & Lehman, 2017; Djemiel, Grec, & Hawkins, 2017; Dong et al, 2017; Farmer et al, 2017; Li et al, 2016). For example, on the Loess Plateau, plastic film mulching significantly increased soil bacterial diversity and affected soil fungal diversity and community structure by changing soil moisture, soil temperature and NO 3 − ‐N (Huang, Liu, Mou, Zhang, & Jia, 2019). Studies on soil microorganisms under straw incorporation, including on the Loess Plateau, have focused on changes in soil microbial biomass (Chen et al, 2017; Nie, Zhou, Wang, Chen, & Du, 2007), not community composition and structure.…”

The application of plastic film mulch and the return and incorporation of crop straw into topsoil as independent treatments affect soil physicochemical properties, including nutrient balance/cycling. It remains unclear whether combining straw incorporation and plastic film mulch significantly affects soil physicochemical properties and bacterial communities. We conducted a two‐factor (plastic film mulch application and maize straw incorporation) randomized block design experiment with four treatments: no plastic film mulch or straw incorporation (C), plastic film mulch (M), straw incorporation without mulch (CS) and straw incorporation with mulch (MS). Soil was sampled at the end of the growing cycle after 3 years of treatment. Soil organic carbon (SOC), total nitrogen (TN) and nitrate‐nitrogen (NO3−‐N) concentrations significantly improved after straw incorporation. Plastic film mulch had a significant negative effect on soil bacterial richness, whereas straw incorporation had no effect. Straw incorporation had a significant positive effect on bacterial diversity, whereas plastic film mulch had no effect. The MS and M treatments had significantly more Proteobacteria than the C and CS treatments. Formation of the soil bacterial community structure was driven by soil TN, NO3−‐N and SOC in the treatments with straw incorporation, and soil ammonium‐nitrogen (NH4+‐N) in the treatments without straw incorporation. In conclusion, plastic film mulch coupled with straw incorporation can significantly change the taxonomical and functional composition of soil bacterial communities and enhance soil bacterial diversity by affecting carbon and nitrogen cycling in cropland soils of farmland, especially in arid and semiarid regions. Highlights SOC, TN and NO3−–N concentrations significantly improved after straw incorporation Straw incorporation had a greater effect on bacterial communities than plastic film mulch Soil bacterial community structure was driven by soil TN, NO3−–N and SOC after straw incorporation Soil bacterial community structure was driven by soil NH4+‐N without straw incorporation.
