“…Our result that the relative abundance of Firmicutes Statistical R and significance (P) of difference between different groups (organic manure-fertilized and unfertilized soils, stubble-amended and non-amended treatments, low and high moisture levels, and different sampling time) were calculated by analysis of similarities (ANOSIM). changed with the varying stubble-C availability is supported by Pascault et al (2013), who found that the succession of bacterial taxonomic groups occurred in FOM-degrading communities (including Firmicutes) and SOM-degrading communities with the varying C availability. In addition, the amended NoFer soil at low moisture level had an abundant Burkholderiales at days 20 and 200, as well as Actinomycetales at day 80 of the incubation period.…”

“…As the amendment time increases, easily degradable component (e.g., low molecular carbohydrates, cellulose, and hemicellulose) of stubble is generally consumed by some copiotrophs, and the remainder (e.g., lignin and polyphenols) is recalcitrant and mainly degraded by oligotrophs. Previous reports have described that copiotrophic bacteria (e.g., Alpha-, Beta-, Gammaproteobacteria, and Bacteroidetes) thrived under conditions where substrate availability was high (Fierer et al, 2007;Eilers et al, 2010;Nemergut et al, 2010), whereas oligotrophic bacteria (e.g., Deltaproteobacteria and Acidobacteria) were more abundant under nutrient-limited conditions (Bernard et al, 2007;Bastian et al, 2009;Pascault et al, 2013). The significant decrease in the relative abundance of Burkholderiales (belonging to Betaproteobacteria) at days 80 and 200 compared to day 20 of the incubation period, and the consistent decrease in the relative abundance of Sphingobacteriales (belonging to Bacteroidetes) with increasing amendment time further confirms the copiotrophic/oligotrophic model.…”

“…We observed that stubble mineralization rate was fast at 55% of the WHC (Chen et al, 2014b), implying a marked decrease of degradable stubble-C at day 200 of the incubation period. At this time, the growth of Acidobacteria, Deltaproteobacteria, and Gemmatimonadetes may be stimulated, because these bacteria are K-strategists (Pascault et al, 2013;Sun et al, 2013).…”

“…straw residues, detritusphere, and bulk soil). Pascault et al (2013) reported that the dynamics and identity of the bacterial groups depend on the residues added; Firmicutes dominate in the wheatamended treatment and Proteobacteria in the alfalfa-amended treatment. Many studies deal with the effects of straw residues and moisture level on soil bacterial community structure using some traditional approaches, such as phospholipid fatty acid (PLFA) analysis (Bossio and Scow, 1998;Drenovsky et al, 2004), DNA cloning and sequencing after denaturing gradient gel electrophoresis (DGGE) (Weber et al, 2001), and direct sequencing after RNA reverse transcription-polymerase chain reaction (RT-PCR) (Peltoniemi et al, 2012), although these methods provide little detail about the taxonomic composition and the phylogenetic structure of bacterial community.…”

It is of ecological significance to investigate microbial communities in response to straw amendment and moisture in arable soils. However, in Chinese fluvo-aquic soils, these responses are still poorly understood. We designed an incubation experiment involving two soils with and without the addition of maize stubble at two moisture levels, and bacterial community structure at days 20, 80, and 200 after the start of incubation was assessed via bar-coded pyrosequencing of the 16S rDNA amplicons. In the presence of stubble with identical moisture level, we observed higher bacterial diversity and richness in long-term organic manure-fertilized soil compared with the unfertilized soil at days 20 and 80, which we attributed to the different quality and quantity of organic matter between the two soils. However, there was no significant difference in bacterial diversity and richness between the two soils at day 200, indicating that long-term straw amendment probably lessens the difference in bacterial community structure between the two soils. In the amended soils bacterial diversity, richness, and community composition at 25% of the water-holding capacity distinctly differed from those at 55% of the waterholding capacity, indicating that moisture strongly affects bacterial distribution in the amended soils. As stubble-C availability declined over time, the dominance of copiotrophic population weakened, and oligotrophic population was moderately abundant. Finally, our study suggests that dissolved organic carbon, which drives redistribution in copiotrophic and oligotrophic categories in response to the varying water and stubble-C availability, is a determinant of bacterial community composition in the amended soils.

Purpose Returning crop straw into fields is a typical agricultural practice to resolve an oversupply of straw and improve soil fertility. Soil microorganisms, especially eukaryotic microorganisms, play a critical role in straw decomposition. To date, microbial communities in response to straw amendment at different moisture levels in Chinese fluvo-aquic soil are poorly understood. The aim of this study was to explore the effects of straw amendment and moisture on microbial communities in Chinese fluvo-aquic soil. Materials and methods Two soils (one was applied with organic manure, and the other was not applied with any fertilizer) from a long-term field experiment in the North China Plain were collected. Soils with and without straw amendment at 25 and 55 % of the average water-holding capacities of the two soils were incubated at 25°C for 80 days. All treatments were sampled 20 and 80 days after the start of incubation. Microbial biomass and community structure were analyzed by phospholipid fatty acids (PLFA) assay, and the eukaryotic diversity and community composition were assessed via barcoded pyrosequencing of the 18S ribosomal RNA (rRNA) gene amplicons.Results and discussion PLFA analysis showed that straw amendment increased the biomass of Gram-positive bacteria, Gram-negative bacteria, actinobacteria, and fungi and shifted microbial community structure. The varied straw availability resulted in a large variation in microbial community structure. In the presence of straw, actinobacterial and fungal biomass both decreased under high moisture content. 18S rRNA gene pyrosequencing indicated that straw amendment decreased eukaryotic diversity and richness and probably restructured the eukaryotic community. Under identical moisture content, long-term organic manure-fertilized soil had higher eukaryotic diversity and richness than the unfertilized soil. In the amended soils under high moisture content, the relative abundance of dominant fungal taxa (Dikarya subkingdom, Ascomycota phylum, and Pezizomycotina subphylum) decreased. Conclusions Straw amendment increases microbial biomass, shifts microbial community structure, and decreases eukaryotic diversity and richness. High moisture content probably has a negative effect on fungal growth in the amended soils. In conclusion, microbial communities in Chinese fluvo-aquic soil are significantly affected by straw amendment at different moisture levels.

The soil physicochemical properties were affected by different fertilizer management, and the soil microbial communities were also changed. However, there is limited information about influence of long-term fertilizer management on soil bacterial diversity in a double-cropping rice (Oryza sativa L.) field. Therefore, the 34-yr long-term fertilizer regime on soil bacterial diversity in a doublecropping paddy field of southern China were studied by using Illumina sequencing and quantitative technology in the present paper. The filed experiment were including mineral fertilizer alone (MF), rice straw residue and mineral fertilizer (RF), 30% manure and 70% mineral fertilizer (OM), and without fertilizer input as control (CK). The results indicated that application of manure and rice straw residue management increase soil volumetric water content, NO 3 −N and NH 4 −N contents. Compared with CK treatment, the diversity indices of soil microbial communities, value of Richness, Shannon and McIntosh indices, and taxonomic diversity were increased with RF and OM treatments. The phyla Planctomycetes, Acidobacteriales, Fimicutes, and Actinobacteria were the most abundant in the soil samples. Application of manure and rice straw residue management increase soil bacterial abundance of the phylum Proteobacteria, Actinobacteria, and Gammaproteobacteria. Meanwhile, the results also showed that there was a significant correlation between soil texture and relative abundances of Acidobacteriales, Firmicutes, Actinobacteria, Gemmatimonadetes, and Alphaproteobacteria. Therefore, the combined application of manure or rice straw residue with mineral fertilizer management could significantly increase the abundance of profitable functional bacteria species and soil nutrient status in a double-cropping rice field of southern China.
