“…Many studies have demonstrated that the composition of microbial community in the rhizosphere can be altered by biotic factors, such as plant species (Grayston et al 1998;Haichar et al 2008), soil type (Berg and Smalla 2009;Lundberg et al 2012), and organic amendments (Alguacil et al 2011;Jack et al 2011). Because of the methodological limitations (Yu et al 2013), most researches have focused on shifts in the composition of the rhizosphere bacterial community in response to the application of organic amendments, whereas few data are available for the composition of fungal community.…”

In our previous work, applying biofertilizer containing Bacillus amyloliquefaciens strain NJN-6 to a banana orchard infected by a serious Fusarium wilt disease over two consecutive years effectively controlled this soil-borne disease. In this study, deep pyrosequencing of 16S ribosomal RNA (rRNA) genes and internal transcribed spacer (ITS) sequences was performed to investigate how the composition of rhizosphere microbial community responded to the application of biofertilizer (BIO), pig manure compost (PM), and chemical fertilizer (CF) and to explore the potential correlation between the microbial community composition and the Fusarium wilt disease. A total of 104,201 bacterial 16S rRNA genes and 154,953 fungal ITS sequence reads were obtained after basic quality control, and Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria, and Ascomycota were the most abundant bacterial and fungal phyla across all samples. Compared with the PM and CF control, the alpha diversity of bacteria significantly (P<0.05) increased, whereas the value of the fungi was significantly (P<0.05) reduced following two consecutive years of biofertilizer application. Moreover, the abundance of Acidobacteria (Gp1 and Gp3), Firmicutes, Leptosphaeria, and Phaeosphaeriopsis was significantly (P < 0.05) increased, while the abundance of Proteobacteria and Ascomycota was significantly (P<0.05) decreased in the BIO treatment. Furthermore, the abundance of Fusarium, a causal pathogen for Fusarium wilt disease, was significantly (P<0.05) reduced in the BIO treatment compared with the CF control and was slightly reduced (not significant) compared with the PM control. Interestingly, the disease incidence was negatively correlated with the enriched taxa of Acidobacteria (Gp1 and Gp3) and Firmicutes, Leptosphaeria, and Phaeosphaeriopsis but positively correlated with abundance of Proteobacteria, Ascomycota, Fusarium, Cylindrocarpon, Gymnascella, Monographella, Pochonia, and Sakaguchia taxa. The results from this study suggest that 2 years of biofertilizer application manipulated the composition of rhizosphere microbial community and induced the Fusarium suppression by increasing bacterial diversity and potentially stimulating microbial consortia taxa, such as Acidobacteria (Gp1 and Gp3), Firmicutes, Leptosphaeria, and Phaeosphaeriopsis.

“…We chose to work with VF because of the physical and biological benefits expected from vermicompost in horticultural cropping systems [17][18][19][20][21]. These properties are associated with the feedstuff given to the earthworms and the microbial community associated with the earthworms [22][23][24]. Vermicompost is produced by vermicomposting or vermifiltration [25].…”

Effect of Three Types of Exogenous Organic Carbon on Soil Organic Matter and Physical Properties of a Sandy Technosol

Technosols made by covering agricultural soils with coastal sediments need additional organic matter (OM) to be suitable for agricultural use. Climate change will likely increase the frequency and intensity of droughts in several areas. The choice of the nature and quantity of OM to add depends on dose-response curves for soil quality. This study quantifies the influence of three contrasting organic materials (vermicompost (VF), green waste compost (GWC) and dairy manure (DM)) on four soil properties: soil organic carbon, evaporation rate, bulk density and structural stability. Soil was sampled in April and May 2014 in an artificial crop field of the vegetable production basin of Mont Saint-Michel (France) made with sediments from the bay of Mont Saint-Michel in 2013. Increasing the dose of OM increased soil organic carbon from 10 to 45 g C kg −1 dry soil and increased the porosity and the structural stability, thus decreasing compaction. Increasing the dose of OM also decreased the evaporation rate. VF and DM had similar effects, while those of GWC were weaker. Compared to DM, VF had greater biological stability. Therefore, high OM inputs along with soil decompaction can increase drought resistance by increasing rooting depth and water retention.

“…They found differences in the bacterial community structure between the different amendments and these differences persisted for at least one month after seedlings were transplanted to the field. Since both compost and vermicompost were made from the same parent material, such differences could be due to the way in which the organic matter was processed prior to the amendment [102]. Previous comparisons between vermicompost and compost with respect to microbial communities [103][104][105] are difficult to interpret because different feedstocks were used for each process.…”

“…Interestingly, Aira et al [100] observed that the effect of the addition of vermicompost occurred despite the low dose used (25% of total fertilisation), and despite the short duration of the experiment (four months). Jack et al [102] also examined how different organic transplant media amendments, including vermicompost, thermogenic compost and industry standard amendments affected the rhizosphere bacterial communities of organically produced tomato plants. They found differences in the bacterial community structure between the different amendments and these differences persisted for at least one month after seedlings were transplanted to the field.…”
