“…The application of RGS promoted the growth of some beneficial microorganisms, sharing an antagonistic effect on soil-borne pathogens and indicating improved plant growth due to the release of active metabolites, e.g., rhizobacteria Bacillus , which is capable of fighting against phytopathogens by releasing active secondary metabolites [34]. Our results were supported by a previous study [36]. Xanthomonadales are known to be hydrocarbon decomposers, and have the ability to obtain carbon from co-existing microorganisms [37].…”

The incorporation of plant residues into soil can be considered a keystone sustainability factor in improving soil structure function. However, the effects of plant residue addition on the soil microbial communities involved in biochemical cycles and abiotic stress phenomena are poorly understood. In this study, experiments were conducted to evaluate the role of raw garlic stalk (RGS) amendment in avoiding monoculture-related production constraints by studying the changes in soil chemical properties and microbial community structures. RGS was applied in four different doses, namely the control (RGS0), 1% (RGS1), 3% (RGS2), and 5% (RGS3) per 100 g of soil. The RGS amendment significantly increased soil electrical conductivity (EC), N, P, K, and enzyme activity. The soil pH significantly decreased with RGS application. High-throughput Illumina MiSeq sequencing revealed significant alterations in bacterial community structures in response to RGS application. Among the 23 major taxa detected, Anaerolineaceae, Acidobacteria, and Cyanobacteria exhibited an increased abundance level. RGS2 increased some bacteria reported to be beneficial including Acidobacteria, Bacillus, and Planctomyces (by 42%, 64%, and 1% respectively). Furthermore, internal transcribed spacer (ITS) fungal regions revealed significant diversity among the different treatments, with taxa such as Chaetomium (56.2%), Acremonium (4.3%), Fusarium (4%), Aspergillus (3.4%), Sordariomycetes (3%), and Plectosphaerellaceae (2%) showing much abundance. Interestingly, Coprinellus (14%) was observed only in RGS-amended soil. RGS treatments effectively altered soil fungal community structures and reduced certain known pathogenic fungal genera, i.e., Fusarium and Acremonium. The results of the present study suggest that RGS amendment potentially affects the microbial community structures that probably affect the physiological and morphological attributes of eggplant under a plastic greenhouse vegetable cultivation system (PGVC) in monoculture.

“…Under CT, the most positively affected genera belonged to Acidobacteria, Firmicutes, Planctomycetes and Verrucomicrobia (Figure 3). Bacteria belonging to the phyla Acidobacteria, Planctomycetes and Firmicutes are considered to grow more efficiently in degraded soils (Chávez-Romero et al, 2016;Ortiz-Cornejo et al, 2017) and can be induced by soil disturbance (Liu et al, 2016), or can endure disadvantageous circumstances owing to endospore production (Lienhard et al, 2014 (Lienhard et al, 2014) and can degrade recalcitrant organic compounds (Bernard et al, 2007).…”

Conservation tillage is an alternative to conventional tillage (CT) for addressing the issue of soil degradation, while how it affects soil quality remains unclear. To characterise the temporary and stable effects of 8 years of conservation tillage on soil quality, topsoil (0-20 cm) properties, 16S rDNA-based bacterial community properties and their relationships were analysed. Three tillage practices (CT [as the control], subsoiling tillage [ST] and no tillage [NT]) were compared at the sowing and harvest stages of a continuous winter wheat (Triticum aestivum L.) system. The mean weight diameter of the water-stable aggregate, organic matter, total N/P/K and available K consistently improved with NT at both crop stages, with averages of 26.8, 35.3, 38.5, 29.2, 13.1 and 59.1%, respectively. Similar but lower levels of improvements were observed under ST. Tillage did not significantly affect soil bulk density, penetration resistance and temperature, whereas NT significantly decreased capillary porosity by 7.9% at sowing. At the sowing stage, CT showed higher bacterial α/β-diversity but lower soil water content and abundances of N-cycling bacteria. The physicochemical properties showed significant correlation with the abundances of some genera belonging to Proteobacteria, Nitrospirae and Actinobacteria. After 8 years of experimentation, we found that conservation tillage, especially NT, resulted in stable effects on soil aggregation and nutrient storage. Although soil compaction temporarily decreased after CT, the bacterial community, soil water storage and the aforementioned stable effects were more favourable for soil sustainability under conservation tillage.

“…Our data confirm that a higher amount of incorporated garlic substrate significantly amplified the organic content ( Table 2 ). The physical availability of organic substrates in extensively manipulated soil could rejuvenate the long-term deficiency of the OM [ 43 , 44 ]. Moreover, crop residue had pronounced and variable effects on the soil C content with time, and this may lead to a more significant net N mineralization [ 44 ].…”

Garlic substrate could influence plant growth through affecting soil microbiome structure. The relationship mechanism between changes in soil microbial communities, disease suppression and plant development, however, remains unclear, particularly in the degraded soil micro-ecological environment. In this study, garlic substrates as a soil amendment were incorporated with different ratios (1:100, 3:100 and 5:100 g/100 g of soil) in a replanted disturbed soil of long-term cucumber monoculture (annual double cropping system in a greenhouse). The results indicated that higher amount of C-amended garlic substrate significantly induced soil suppressiveness (35.9% greater than control (CK) against the foliar disease incidence rate. This inhibitory effect consequently improved the cucumber growth performance and fruit yield to 20% higher than the non-amended soil. Short-term garlic substrate addition modified the soil quality through an increase in soil organic matter (SOM), nutrient availability and enzymatic activities. Illumina MiSeq sequencing analysis revealed that soil bacterial and fungal communities in the garlic amendment were significantly different from the control. Species richness and diversity indices significantly increased under treated soil. The correlation-based heat map analysis suggested that soil OM, nutrient contents and biological activators were the primary drivers reshaping the microbial community structure. Furthermore, garlic substrate inhibited soil-borne pathogen taxa (Fusarium and Nematoda), and their reduced abundances, significantly affecting the crop yield. In addition, the host plant recruited certain plant-beneficial microbes due to substrate addition that could directly contribute to plant–pathogen inhibition and crop biomass production. For example, abundant Acidobacteria, Ascomycota and Glomeromycota taxa were significantly associated with cucumber yield promotion. Firmicutes, Actinobacteria, Bacteroidetes, Basidiomycota and Glomeromycota were the associated microbial taxa that possibly performed as antagonists of Fusarium wilt, with plant pathogen suppression potential in monocropped cucumber-planted soil.
