Microbiome diagnostics for successful inoculation with biofertilizer

Summary

This presentation shows that the success of arbuscular mycorrhizal fungi (AMF) biofertilizer inoculation is highly context-dependent and can be predicted using soil microbiome diagnostics. Based on 54 maize field experiments across Switzerland, the study demonstrates that fungal community composition explains most of the variation in mycorrhizal growth response, whereas soil physico-chemical properties are less influential. The results highlight the potential of microbiome-based diagnostics to guide targeted biofertilizer use and improve sustainable nutrient management in agriculture.
