“…In the present study, the results showed that bacterial composition was similar in different soil samples at phyla level; relative abundance was different. The dominant phyla (relative abundance > 5%) were Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria, and Gemmatimonadetes, which were observed in this study across all soil samples that roughly represent the 26 soil types across the black soils of northeastern China as reported by Liu et al (Liu et al 2014), whereas the relative abundance of Planctomycetes in the soil samples was < 1%, which is similar to that found in previous studies (Chu et al 2010), but over five times lower than the abundance reported by Liu et al and Ding et al (Liu et al 2014;Ding et al 2016).…”

Purpose To understand which environmental factors influence the distribution and ecological functions of bacteria in agricultural soil. Method A broad range of farmland soils was sampled from 206 locations in Jilin province, China. We used 16S rRNA genebased Illumina HiSeq sequencing to estimated soil bacterial community structure and functions. Result The dominant taxa in terms of abundance were found to be, Actinobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, and Proteobacteria. Bacterial communities were dominantly affected by soil pH, whereas soil organic carbon did not have a significant influence on bacterial communities. Soil pH was significantly positively correlated with bacterial operational taxonomic unit abundance and soil bacterial α-diversity (P<0.05) spatially rather than with soil nutrients. Bacterial functions were estimated using FAPROTAX, and the relative abundance of anaerobic and aerobic chemoheterotrophs, and nitrifying bacteria was 27.66%, 26.14%, and 6.87%, respectively, of the total bacterial community. Generally, the results indicate that soil pH is more important than nutrients in shaping bacterial communities in agricultural soils, including their ecological functions and biogeographic distribution.

“…This emphasizes the strong influence environmental extent has on the identity of environmental variables that drive variation in community composition (Stegen et al., 2016b). Furthermore, it is well known that for upland soils, long‐term chemical fertilizer application can decrease soil pH (Ding et al., ; Liu et al., 2015a), and organic matter amendments shift soil pH towards neutral (Lin et al., ). Consistent with these previous studies, OMN resulted in relatively neutral soil pH compared to lower pH in NPK, except for the Changshu and Yingtan sites (Supporting information Table ).…”

Two key features influencing community assembly processes at regional scale: Initial state and degree of change in environmental conditions

et al. 2018

Belowground microbial communities strongly influence ecosystem function such that predicting function may rely on understanding ecological processes that assemble communities. Uncertainty remains, however, in what governs the relative contributions of different ecological processes. To help fill this knowledge gap, we test the general hypothesis that both initial state and degree of change in environmental conditions govern the relative contributions of different ecological assembly processes. To do so, we leveraged regional‐scale nutrient and organic matter addition experiments and used soil organic matter (SOM) as a proxy of integrated soil environmental conditions. Consistent with our hypothesis, we found that both the initial amount of SOM and the degree of change in SOM—in response to nutrient addition—influenced the relative contributions of different ecological assembly processes. These influences were most clearly observed at the regional scale, suggesting potential scale dependence. More specifically, nutrient additions homogenized bacterial community composition due to enhanced influences of homogenizing dispersal when SOM content was initially high. In contrast, nutrient additions led to divergence in community composition due to variable selection when initial SOM was low and/or when SOM increased significantly in response to nutrient additions. Our findings indicate important connections among initial conditions, degree of change in environmental variables and microbial community assembly processes that may influence ecosystem processes. These conceptual inferences highlight a need to strengthen connections between ecological theory and biogeochemical modelling.

“…Of course, the nutrients addition into soil through different kinds of fertilizer also have a great influence to the soil microbial composition and diversity. The combination application of inorganic and organic fertilizer (MF, W2MF, and W4MF) was proven to significantly increase soil microbial diversity and shift their composition (Ding et al, 2016). Ji et al (2018) found that added N‐P‐K plus organic fertilizer into the tea planted agricultural soil induced significant bacterial community structure and composition shifts, and increased bacterial diversity.…”

Biochar‐based fertilizer treatments induced significant microbial community structure shifts compared with no‐biochar and biochar alone. Biochar‐based fertilizer especially at higher biochar addition rate increased soil microbial biomass and fertility. Soil microbial species were strongly correlated with soil nutrients under biochar and biochar‐based fertilizer into karst soil. Karst ecosystems are vulnerable to degradation and constitute a significant proportion of southwestern China. Here, we explore the amendment of these soils with wood biochar in combination with N‐P‐K fertilizer and swine manure compost with the goal of improving microbial community structure and soil nutrient status of these soils. A pot experiment with six treatments, including control (CK, no amendment), swine manure compost plus N‐P‐K fertilizer (MF), wood biochar at 2% in soil (W2), wood biochar at 4% in soil (W4), wood biochar‐based fertilizer at 2% in soil (W2MF), and biochar‐based fertilizer at 4% in soil (W4MF), was set up for 20 months. The results showed that soil organic matter and soil available nutrients N, P, and K in W4MF increased by 63.95, 66.23, 284.96, and 94.56%, respectively, compared with CK. Soil microbial biomass C, N, and P increased in sequence by 60.05, 87.64, and 307.85%, respectively. Soil bacterial and fungal diversity indices (Simpson and Shannon) and richness index (Chao1) were generally higher in biochar‐based fertilizer treatments (W2MF and W4MF) than biochar alone (W2 and W4). The bacterial and fungal community structures of biochar based fertilizer treatments differed from those of biochar amendment alone or control (P < 0.05). Linear discriminant (Effect Size) analysis showed that the bacterial biomarkers of the W2MF + W4MF group were mainly the phylum Acidobacteria and class Alphaproteobacteria, and the fungal biomarkers were the phylum Rozellomycota and Glomeromycota. Redundancy analysis revealed strong relationships between microbial community structure and soil organic matter and soil available nutrients N, P, and K (P < 0.05). In conclusion, either sole biochar or biochar‐based fertilizer amendment improved karst soil nutrient conditions and induced microbial community structural shifts. The performance was better in biochar‐based fertilizer treatment than that in biochar addition alone.
