Soil Microbiome Engineering in Sustainable Agriculture: A Comprehensive Review

Abstract

Soil microbiome engineering, a frontier within sustainable agriculture, involves the manipulation as well as stewardship of soil microbial communities to improve crop productivity, restore soil health and address climate-related challenges. This review critically synthesizes recent advances in microbial inoculants, as well as engineered synthetic communities with host-mediated genetic strategies aimed at improving plant performance in fluctuating environments. Recent developments in synthetic microbial consortia design demonstrate enhanced colonization efficiency and synergistic interactions that surpass single-strain inoculants, multi-strain communities showing yield improvements across diverse agroecosystems. Special emphasis is placed on mechanisms, cost–benefit considerations, and case studies demonstrating agronomic and ecological potential across different cropping systems. This discussion also covers environmental, economic, policy factors plus opportunities and lasting issues like biosafety fears, rules, farmer uptake. Soil microbiome engineering combines perceptions from multi-omics, digital technologies, and synthetic biology providing scalable solutions for nutrient management, disease suppression, and stress resilience. Key bottlenecks are field-to-lab translation gaps, economic scalability, identified in this type of review. Academics, regulators, and industry are guided toward responsibly embedding microbiome engineering into global food systems with future research pathways that are also outlined.
