“…The rhizosphere microbial communities exhibited distinctly different patterns between soil and substrate. Our soil results are consistent with the findings of previous studies that applied functional bacteria or fungi present in biofertilizers to alter the bacterial taxonomic composition of the soil 48 .…”

Reductions in the quality and yield of crops continuously produced in the same location for many years due to annual increases in soil-borne pathogens. Environmentally-friendly methods are needed to produce vegetables sustainably and cost effectively under protective cover. We investigated the impact of biofertilizers on cucumber growth and yield, and changes to populations of soil microorganisms in response to biofertilizer treatments applied to substrate or soil. We observed that some biofertilizers significantly increased cucumber growth and decreased soil-borne pathogens in soil and substrate. Rhizosphere microbial communities in soil and substrate responded differently to different biofertilizers, which also led to significant differences in microbial diversity and taxonomic structure at different times in the growing season. Biofertilizers increase the prospects of re-using substrate for continuously producing high-quality crops cost-effectively from the same soil each year while at the same time controlling soil-borne disease.

“…The biological solubilization of phosphate is an essential aspect of the formulation of biofertilizer to increase the yield of crops (Borgi et al, 2020). Biofertilizers are biologically active formulations containing beneficial living micro‐organisms which, when applied to seed, plant surfaces or soil, colonizes the rhizosphere or the interior of the plant and promotes the growth by enhancing the supply of plant growth‐promoting substances or nutrients (Li et al, 2022; Raimi et al, 2021). Reports suggest that the addition of biofertilizer during composting strengthens the indigenous microbiome and produces a better quality product (Wei et al, 2017).…”

Aims:The present study was carried out to design a phosphate solubilizing bacterial (PSB)-based biofertilizer using locally produced fruit waste. Method and results:Two PSB strains Pseudomonas aeruginosa CMG4 and AAC1 were inoculated into compost. Six compost piles were prepared with carbon:nitrogen (C:N) ratio 30:1. Four piles were inoculated with PSB and two piles served as a control. After 125 days, composts were considered mature at 29-31°C in the pH range of 7.1-7.3 and 32%-35% moisture content (MC). Accessible calcium (Ca) content increased up to 50 g kg −1 . Microbial analysis showed the survival of P. aeruginosa species in the maturing compost even at higher temperature (~53°C). Native bacterial load was retrieved in the range of 10 9 -10 11 CFUg −1 . Heavy metal concentrations including copper (Cu), lead (Pb), chromium (Cr) and cadmium (Cd) were found to occur below critical thresholds. Seed germination index for compost toxicity was found to be >80%, significantly higher than animal manure and chemical fertilizer, that is, 78% and 31%, respectively, suggesting non-toxicity. Conclusions:The evaluation of prepared compost by physicochemical parameters revealed that inoculation of P. aeruginosa does not affect the temperature, MC, carbon to nitrogen ratio, organic matter and Mg content but significantly increased the accessible Ca content, suggesting the solubilization of inorganic Ca bound phosphate. Compost was safe in terms of heavy metal concentration and seed germination. Significance and impact of study:This study encourages that the PSB-rich tailored compost can be utilized as a phosphatic biofertilizer to fulfil the demand for phosphorus which would improve and sustain soil fertility.

“…A random forest model was conducted by using the 'randomForest' R package to identify the biomarker taxa correlated with AM fungi symbiosis. Cross-validation was conducted using the rfcv() function to choose appropriate characteristics, and the varImpPlot function was used to determine the importance of characteristics in the classification (Li et al, 2022). The importance of characteristics and the cross-validation curve were visualized using the ggplot2 package (Wickham, 2016).…”

Mycorrhizal fungi alter root exudation to cultivate a beneficial microbiome for plant growth

Rhizospheres are crucial for plant health, containing complex microbial communities that have been referred to as the second genome of plants (Zhang et al., 2022). Plant roots release exudates into the rhizosphere, attracting micro-organisms that feed on the rhizodeposits (Perreault & Laforest-Lapointe, 2022). Direct interactions between roots and micro-organisms significantly affect plant growth, health and adaptation (Petipas et al., 2021;Zhang et al., 2017). Indirect rhizospheric interactions between beneficial and plant-pathogenic micro-organisms are also mediated by signals secreted from the plant roots (Macabuhay et al., 2022). Plants have species-specific effects on the relative abundance and composition of rhizospheric mi-
