Abstract

The different components of the root zone (plant, microbiome, and rooting medium) can be engineered to enhance crop production sustainably by applying plant growth-promoting rhizobacteria (PGPR). Multispecies microbial inocula may be more effective in improving plant performance than single species PGPRs because they can better establish.
In soilless systems, the selection of the plant growing medium raw materials plays a crucial role in the effectiveness of bacterial community amendment.
Therefore, we investigated the effect of transplanting bacterial community inocula on lettuce (Lactuca sativa L.) root-associated bacterial community functioning inside a vertical farm.
We found that the raw materials had distinct resident bacterial community structures and amending a bacterial community to the plant growing media allowed more control over the final root-associated bacterial community structure than a single species PGPR inoculum.
