“…Blaya et al (2016) [344] evaluated the microbial structure of a set of four diseasesuppressive composts from vineyard pruning wastes mixed with pepper sludge, pepper wastes, and other vegetable wastes showing different suppressiveness degrees against Phytophthora diseases (damping-off and root rot) by Phytophthora nicotianae in pepper. Chilosi et al (2017) [345] produced and tested several on-farm green composts from residues of pruning of woody plants and grass clippings in a lavender nursery system against Rhizoctonia damping-off by R. solani, Phytophthora root diseases by P. nicotianae and Sclerotinia root rot by S. sclerotiorum in lavender, obtaining a significant suppression in potting soil for all pathogens. Besides, further research on this topic has been conducted by authors who produced in situ and tested different collections of on-farm green compost.…”

This review pays attention to the newest insights on the soil microbiome in plant disease-suppressive soil (DSS) for sustainable plant health management from the perspective of a circular economy that provides beneficial microbiota by recycling agro-wastes into the soil. In order to increase suppression of soil-borne plant pathogens, the main goal of this paper is to critically discuss and compare the potential use of reshaped soil microbiomes by assembling different agricultural practices such as crop selection; land use and conservative agriculture; crop rotation, diversification, intercropping and cover cropping; compost and chitosan application; and soil pre-fumigation combined with organic amendments and bio-organic fertilizers. This review is seen mostly as a comprehensive understanding of the main findings regarding DSS, starting from the oldest concepts to the newest challenges, based on the assumption that sustainability for soil quality and plant health is increasingly viable and supported by microbiome-assisted strategies based on the next-generation sequencing (NGS) methods that characterize in depth the soil bacterial and fungal communities. This approach, together with the virtuous reuse of agro-wastes to produce in situ green composts and organic bio-fertilizers, is the best way to design new sustainable cropping systems in a circular economy system. The current knowledge on soil-borne pathogens and soil microbiota is summarized. How microbiota determine soil suppression and what NGS strategies are available to understand soil microbiomes in DSS are presented. Disturbance of soil microbiota based on combined agricultural practices is deeply considered. Sustainable soil microbiome management by recycling in situ agro-wastes is presented. Afterwards, how the resulting new insights can drive the progress in sustainable microbiome-based disease management is discussed.

“…Trichoderma compost gave a good protection against lentil root rot disease caused by S. rolfsii (Shahiduzzaman, 2015). Also, Chilosi et al (2017) found that green nursery compost fortified with T. harziaum markedly reduced root rot disease of ornamental plants caused by S. sclerotiorum.…”

ompost was used as soil treatment either single or mixed with Trichoderma harzianum, Pseudomonas flourescens and Glomus sp. to study their efficiency against guar (Cyamopsis tetragonoloba) root rot caused by Sclerotium rolfsii. In vitro, among different bacteria isolated from compost wash, two isolates showed strong inhibitory effect against mycelial growth of S. rolfsii and were identified as Bacillus subtilis and B amyloliquefaciens using Genetic analyzer (Applied Biosystem, Hitachi 3500).In the present work, mixed compost and bioagents was used to decrease disease incidence of root rot in guar plants. In pot experiments, soil amended with compost alone or mixed with bioagents provided a good protection against root rot. Soil amended with compost mixed with T. harzianum or P. fluorescens were superior that produced 82.35% and 76.48% decrease, respectively. Microbial population in the plant rhizosphere increased significantly as a result of application of compost alone or mixed with bioagents. Negative correlation was found between disease incidence and microbial population in the rhizosphere. Also, Soil amended with compost alone or mixed with bioagents increased plant nutrient uptake and improved soil fertility (NPK). Marked decrease in sclerotia germination of the pathogen in the soil amended with compost alone or mixed with bioagents was recorded. Soil amended with compost mixed with T.harzianum or P. fluorescens completely inhibited sclerotia germination. The aforementioned treatment not only decreased disease incidence but also increased fresh and dry weights of the plant as well as number of nodules compared to untreated control. Pilot field experiments are required.

“…Suppression of Rhizoctonia diseases also resulted to be induced by restrict groups of microorganisms acting synergistically [212]. Suppression of Rhizoctonia dampingoff, collar rot and root rot by soil amendment with green composts resulted to be most variable and unpredictable in many horticultural soil-less systems [45,120,122,175]. The primary mechanism of action ascribed to Trichoderma harzianum in suppressing Rhizoctonia diseases is primarily related to cell wall degrading of the pathogen due to action of lytic enzymes such as β-1,3-glucanase, chitobiase, hydrolases and chitinase [59].…”

“…Soil management by amendment with tailored diseasesuppressive composts from green wastes resulted to be a consolidated strategy that induces significant shifts of the soil microbiota toward beneficial consortia for effectively controlling soil-borne pathogens [45,54,149,154]. This paper focusses its interest on the most recent findings related to a next-generation composts' collection (Table 2) coming from green sources (plant wastes, agroindustrial residues and agro-wastes) and wet biomass wastes (municipal organic solid waste and co-composted animal manure with household waste).…”

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.
