“…The application of organic manures increases soil pH, decreases exchangeable Al 3+ concentration [30], and increases nutrient (Ca 2+ and Mg 2+ ) concentrations in acid soils [37]. In addition, organic amendments modify the structure of the soil microbiome [38], enhance soil quality and increase total soluble solids in apple trees [39]. How to synchronize soil quality, banana yield and quality is important in banana plantation.…”

Low soil fertility, high rates of fertilizer application and low yields and quality are major problems in intensive banana production in acid soils of south China. A field experiment was carried out for two years to determine the optimum management practices for maximizing soil health and banana yield and quality. The experiment consisted of an unamended control (CK) and lime (Lime), calcium magnesium phosphate fertilizer (CMP), organic fertilizer (OF), and organic fertilizer combined with calcium magnesium phosphate fertilizer (OFC) treatments. Soil nutrient concentrations and banana shoot biomass, nutrient uptake, yield and fruit quality were determined. Application of lime and CMP was found to increase soil pH and nutrient availability and increase banana yield. Yet, the banana biomass and yields in the Lime and CMP treatments were significantly lower than those in the OF and OFC treatments in which soil organic matter (SOM) content increased. Total soluble solids and soluble sugar contents increased in the CMP and organic fertilizer treatments. A consistent increase in Mg concentrations in banana leaves over the two years in the CMP and organic fertilizer treatments indicates that Mg is essential for banana production and quality. Shortterm adding Mg from banana corms increased total soluble solids and soluble sugar content. The application of organic fertilizer combined with CMP or Mg solution is therefore recommended to increase soil health and promote the yield and quality of banana in intensively managed plantations in subtropical regions.

“…NMDS and MRT both revealed significant differences in bulk soil bacterial and fungal community composition between the different fertilization strategies. This finding indicates that different soil amendments induce differences in microbial composition [30] , and PGPR-containing bio-organic fertilizers have been broadly confirmed to have a significant effect in shaping soil microbial communities [5,10] . Importantly, we found similar variation in bacterial and fungal communities in rhizosphere and bulk soil samples.…”

“…Intensive agricultural practices characterized by the use of chemical fertilizers and pesticides are known to alter soil biology by disrupting biotic interactions [3] . This can lead to the development of damaging soilborne diseases caused by an unbalanced proliferation of a subset of harmful microbes that encompass a set of plant pathogenic fungi and bacteria [4,5] . Among these, Fusarium wilt disease, mainly caused by pathogenic Fusarium oxysporum, is a major factor limiting several cropping systems [6] .…”

“…The rhizosphere is the zone where a complex microbial network interacts with pathogens and influences the outcome of infection [8] . The composition of the resident microbial community in the rhizosphere is of critical importance and has a vital role to the success of pathogen invasion [5,8,10] . Previous studies showed that application of a biofertilizer consisting of Bacillus amyloliquefaciens and compost resulted in the control of Fusarium wilt disease by changing the composition and activity of the resident rhizosphere microbes [4,11] .…”

Harnessing disease-suppressive microbiomes constitutes a promising strategy for optimizing plant growth. However, relatively little information is available about the relationship between bulk and rhizosphere soil microbiomes. Here, the assembly of banana bulk soil and rhizosphere microbiomes was investigated in a monoculture system consisting of bio-organic (BIO) and organic management practices. Applying BIO practice in newly reclaimed fields resulted in a high-efficiency biocontrol rate, thus providing a promising strategy for pre-control of Fusarium wilt disease. The soil microbiota was further characterized by MiSeq sequencing and quantitative PCR. The results indicate that disease suppression was mediated by the structure of a suppressive rhizosphere microbiome with respect to distinct community composition, diversity and abundance. Overall microbiome suppressiveness was primarily related to a particular set of enriched bacterial taxa affiliated with Pseudomonas, Terrimonas, Cupriavidus, Gp6, Ohtaekwangia and Duganella. Finally, structural equation modeling was used to show that the changes in bulk soil bacterial community determined its induced rhizosphere bacterial community, which serves as an important and direct factor in restraining the pathogen. Collectively, this study provides an integrative approach to disentangle the biological basis of disease-suppressive microbiomes in the context of agricultural practice and soil management.

“…Nevertheless, if from one hand OAs can stimulate soil suppressiveness, on the other hand it can increase disease incidence and/ or disease severity inducing soil to become conducive [24]. Despite some contradictory data, the integrated agricultural strategies based on the combined use of OAs and BCAs tailored composts and microbial consortia from disease-suppressive composts, and novel bioorganic fertilizers with organic additives (as silicon and chitin) were accepted worldwide for controlling multiple soil-borne pathogens [50,56,57,97,138,238]. These practices induce rhizosphere health by beneficial alterations of its microbiota.…”

Soil microbiota plays a key role in suppressing soil-borne plant pathogens improving the natural soil suppressiveness. Microbiome disturbance triggers specific perturbation to change and shape the soil microbial communities’ network for increasing suppression against phytopathogens and related diseases. Very important goals have been reached in manipulation of soil microbiota through agronomical practices based on soil pre-fumigation, organic amendment, crop rotation and intercropping. Nevertheless, to limit inconsistencies, drawbacks and failures related to soil microbiota disturbance, a detailed understanding of the microbiome shifts during its manipulation is needed under the light of the microbiome-assisted strategies. Next-generation sequencing often offers a better overview of the soil microbial communities during microbiomes manipulation, but sometime it does not provide information related to the highest taxonomic resolution of the soil microbial communities. This review work reports and discusses the most reliable findings in relation to a comprehensive understanding of soil microbiota and how its manipulation can improve suppression against soil-borne diseases in organic farming systems. Role and functionality of the soil microbiota in suppressing soil-borne pathogens affecting crops have been basically described in the first section of the paper. Characterization of the soil microbiomes network by high-throughput sequencing has been introduced in the second section. Some relevant findings by which soil microbiota manipulation can address the design of novel sustainable cropping systems to sustain crops’ health without use (or reduced use) of synthetic fungicides and fumigants have been extensively presented and discussed in the third and fourth sections, respectively, under the light of the new microbiome-assisted strategies. Critical comparisons on the next-generation sequencing have been provided in the fifth section. Concluding remarks have been drawn in the last section.

Abstract: Aims Bio-organic fertilizer and different additives are widely applied to suppress soil-borne diseases. However, how different additives alter bulk soil microflora and thereby induce the healthy rhizospheric microflora remains unclear.
