Crab shell meal promotes root-knot nematode control through shifts in soil microbial communities and enhanced nitrification.

ABSTRACT: With growing environmental awareness, eco-friendly agricultural practices are gaining increased attention. Among these, crab shell meal (CSM) is recognized for its potential to suppress root-knot nematodes (Meloidogyne spp.), largely through the enrichment of chitinolytic bacteria, particularly members of the phylum Actinobacteriota. However, the broader effects of CSM on the soil microbiome remain poorly understood. This study employed 16S amplicon metagenomics to investigate the impact of CSM application on the soil bacterial community associated with root-knot nematode-infected cucumber (Cucumis sativus L.) in a pot experiment. Plant growth parameters and soil chemical properties were also assessed. CSM application at concentrations ranging from 0% to 4% significantly altered the soil m
