“…In the present study, we found that the proportions of abundant taxa were highly negatively correlated with soil pH, EC, and SOC. Our results were consistent with some other studies that have demonstrated that soil pH was a very strong factor in structuring microbial communities [31,81]. In contrast, the proportions of abundant taxa were positively correlated with soil available P and K ( Table 2).…”

“…The results were also confirmed by the redundancy analysis (RDA) of the abundant taxa and the environmental variables for individual samples during the three years ( Figure 6). Our results are consistent with reports that the physicochemical soil microenvironment has a very strong impact on soil microbial community and structure [31,82,83]. Until now, this interaction between environmental variables and the fungal community has proved to be beneficial to cucumber plants.…”

“…Soil fungal diversity is considered very critical to the long-term sustainability of soil ecosystems, which is usually reduced by agricultural management [62,63]. Recently, studies have demonstrated that greater biodiversity can enhance the ecosystem and the stability of microbial functions [31]. Hence, it is important to maintain and restore fungal biodiversity in sustainable agricultural systems.…”

Abstract:A decreased soil biological environment in terms of an unstable microbial population and diversity index is primarily caused by intensive continuous cropping systems. In this study, a crop rotation system was established to evaluate the soil fungal diversity using a pyrosequencing-based analysis during three successive growing seasons (2013, 2014, and 2015) under a field pot investigation. We found that overall green garlic/cucumber rotational effects increased cucumber productivity under these growing practices. Analysis of fungal communities in rhizosphere soils by high-throughput pyrosequencing showed that the estimated treatment effects were more obvious during the three-year trials, and OTU richness was much higher than the control in cucumber-planted soils. The relative frequencies of fungal diversity showed variable responses before and after rotation practices, and mainly α-diversity of fungi increased in garlic planted soil and again decreased after cucumber planted soil in each year. The phylogenetic classification illustrated that the fungal communities were dominated by the taxa Ascomycota, Basidiomycota, Chytridiomycota, Glomeromycota, and Zygomycota across all samples. Particularly, the relative abundance of the taxon Ascomycota was largely and predominantly enriched with the increasing number of garlic bulbs during the three years. Moreover, the majority of abundant taxa positively correlated with available P and K contents, while being highly negatively correlated with soil pH, EC, and SOC. These results indicate that garlic-cucumber-based crop rotations induce fungal richness and diversity and promote the sustainability of agricultural ecosystems, thus enhancing crop growth and production.

“…Firmicutes have been described as fast-growing copiotrophs that thrive in environments with high carbon availability (Rodrigues et al 2013). Among the classes of Firmicutes, the relative abundance of Bacilli, which are primarily obligate aerobes (Zhao et al 2014), was significantly higher in the chisel plow and zero tillage soils than it was in the plow tillage. The genus Bacillus, which belongs to the class Bacilli and possesses numerous growth-promoting characteristics and is adapted to local conditions (Abiala et al 2015), was the most represented among the Firmicutes in chisel plow and zero tillage (85 % each).…”

Agricultural practices change soil's physical and chemical properties, therefore modifying soil microbial communities. Conservation tillage is widely used to improve the soil texture and nutrient status in the dryland regions of northern China. However, little is known about the influence of soil properties on microbes, in particular on the effect of conservation tillage on soil bacterial communities. Here, we studied the effect of a 5-year tillage treatment on soil properties and soil bacterial communities in the dryland regions of northern China using a high-throughput sequencing technology and quantitative PCR of 16S rRNA genes. We compared the changes in soil bacterial diversity, and composition was measured for conservation tillage, including zero plow or chisel plow, and for conventional tillage using plow. Our results show that conservation tillage increased the Simpson index by 378 % and exhibited significantly dissimilar polygenetic diversity, with r of 1, and taxonomic diversity, of r higher than 0.49, compared to conventional tillage. This finding demonstrates that conservation tillage modifies soil bacterial diversity. Chisel plow and zero tillage increase the abundance of the genus Bacillus, including 85 % of the phylum Firmicutes, and of Rhizobiales belonging to the Alphaproteobacteria. Overall conservation tillage increased the abundance of profitable functional bacteria species.

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.
