Catch crop amendments and microbial inoculants differently modulate apple rhizosphere microbiomes and plant responses.

ABSTRACT: Plant-soil feedback and soil microbial legacies play crucial roles in replanting success of apple. This study investigated how different soil amendment strategies influence these factors in replant disease-affected soil. Two approaches were tested: (i) the preculture and amendment of catch crops-either a single species, Tagetes patula, or a diverse catch crop mixture (CCM), and (ii) the inoculation of plant-beneficial microbes-bacteria, arbuscular mycorrhizal fungi, or their combination (SynC). Apple rootstock M.26 was grown for seven weeks in a greenhouse, and plant growth, soil nutrients, root phytoalexins, and microbial communities in rhizosphere and root-affected soil were analyzed. Catch crop amendments but not microbial inoculations, significantly altered soil nutrients. Root length
