Summary
This four-year field trial in Yunnan Province, China, examined how natural weed cover and Siratro legume cover crop affected soil fungal diversity in banana intercropping systems compared to conventional bare soil management. Siratro significantly increased overall fungal diversity (Shannon and Simpson indices) in 2019–2020, enriched beneficial fungal genera whilst reducing potential pathogens, and enhanced soil microbiome stability through increased network modularity. The findings suggest that legume cover cropping represents a practical approach to improving soil fungal community structure and reducing pathogenic burden in banana production systems.
UK applicability
Direct application to UK banana production is not relevant as bananas are not commercially cultivated in the United Kingdom. However, the methodology and ecological principles demonstrating how legume cover crops enhance soil fungal diversity and reduce pathogenic fungi may inform UK horticulture (e.g. soft fruit, protected crops) or inform regenerative agriculture policy frameworks.
Key measures
Shannon and Simpson diversity indices; fungal community composition via Illumina MiSeq sequencing; relative abundance of specific fungal genera (Mortierella, Acremonium, Plectophaerella, Metarhizium, Acrocalymma, Fusicolla, Myrothecium, Exserohilum, Micropsalliota, Nigrospora); fungal guild distribution (saprotrophs_symbiotrophs, pathogens_saprotrophs); network modularity and co-occurrence patterns
Outcomes reported
The study measured soil fungal community composition and diversity using high-throughput sequencing across three banana production treatments (bare soil, natural weed cover, and Siratro legume cover crop) over four years. Key outcomes included changes in fungal diversity indices, shifts in specific fungal genera abundance, and alterations in fungal functional guilds (saprotrophs, symbiotrophs, and pathogens).
