The future of sustainable agriculture will require practical microbial solutions that reduce chemical inputs while maintaining productivity. While existing literature reviews focus on laboratory science, they rarely address the practicalities of farm implementation. Low rates of adoption suggest a translational gap. This review translates current scientific insights for the relevant end user (farmers). Pesticides and fertilisers disrupt naturally occurring microbial communities that maintain plant health and resilience. Applications of beneficial microbes to restore plant health or improve productivity currently employ single-strain inoculants. The targeted application of a consortium of multiple microorganisms, a “synthetic community” (SynCom), including biocontrol agents, biostimulants and biofertilisers, is superior. The “SynCom” approach could be considered the Swiss army knife of sustainable agriculture, with each member of the community performing overlapping functions. While SymComs have shown success in laboratory and greenhouse trials, field reliability has been inconsistent, either due to variability in production or stability issues in the field. The future of sustainable agriculture will require greater collaboration between scientists and farmers at a local level, specifically, the application of microbes from local soils that are adapted to local environmental conditions, investment in monitoring successes and failures, and application via seed coating using currently available infrastructure.
