Two Distinct Soil Disinfestations Differently Modify the Bacterial Communities in a Tomato Field

Reductive soil disinfestation (RSD) and solarization (SS) were evaluated based on environmental factors, microbiome, suppression of Fusarium oxysporum in a tomato field soil. Soil factors (moisture content, electric conductivity, pH, redox potential (RP)) measured during disinfestations. All more strongly influenced by RSD than SS. 16S rRNA amplicon sequencing RSD- SS-treated soils was performed. The bacterial communities taxonomically functionally distinct depending treatment methods periods significantly correlated with pH RP. Fifty-four pathways predicted PICRUSt2 (third level MetaCyc hierarchy) different between Quantitative polymerase chain reaction demonstrated that both treatments equally suppressed F. oxysporum. growth yield cultivated after similar SS shaped communities, although the effects pathogen plant comparable treatments. existence pathogen-suppressive microbes, other Clostridia previously reported to have an effect, suggested. Comparison provides new aspects unknown patterns usefulness as alternative RSD.
