Effects of Bacillus amyloliquefaciens and different phosphorus sources on Maize plants as revealed by NMR and GC-MS based metabolomics

Aims Plant growth-promoting bacteria of the genus Bacillus are known to solubilize phosphates and enhance plant growth in many plant species. We explored the effects of the inoculation with a commercial isolate Bacillus amyloliquefaciens on the growth and metabolic processes of maize plants in pot soils treated with triple superphosphate, rock phosphate, and either cow- or horse-manure composts, as P-fertilizers.
