Microorganisms such as bacteria are used to help food crops by providing plant nutrients such as phosphorous. Peat moss is presently the most common carrier used to add bacterial inoculants to the soil. However peat moss is a limited natural resource. Therefore Glodowska et al. show that biochar is an alternative inoculant carrier for bacteria. They tested corn growth using the phosphorous-solubilizing bacterium Pseudomonas libanensis.
