Organic Amendments Alter Soil Hydrology and Belowground Microbiome of Tomato (Solanum lycopersicum)

Manure-derived organic amendments are a cost-effective tool that provide many potential benefits to plant and soil health including fertility, water retention, disease suppression. A greenhouse experiment was conducted evaluate how dairy manure compost (DMC), compost-derived vermicompost (VC), dehydrated poultry pellets (PP) impact the tripartite relationship among growth, physiochemical properties, microbial community composition. Of tomato plants with manure-derived fertilizers amendments, only VC led vigorous growth through duration of experiment, whereas DMC had mixed impacts on PP detrimental. Organic increased porosity holding capacity, but delayed maturation decreased biomass. Composition bacterial communities were affected more by amendment than fungal in all microhabitats. outside roots (bulk soil, rhizosphere, rhizoplane) contrasted those within (endosphere). Distinct detected for each treatment, an abundance Massilia, Chryseolinea, Scedosporium, Acinetobacter distinguishing control, vermicompost, compost, pellet treatments, respectively. This study suggests is application not because introduced, also due synergistic effect physical environment. Furthermore, there strong interaction between root spatial heterogeneity root-associated communities.
