Climate change, inadequate possessions, and land degradation all pose obstacles to modern agriculture. In the current scenario, agriculture industry is mainly dependent on use of chemical-based pesticides fertilizers that impact soil health crop productivity. Moreover, water scarcity leads farmers in drastically affected regions heavy metal-enriched sources originating from industrial for field crops irrigation. Soil pollutants can be carried into human body via dust water, creating negative effects varying simple symptoms, e.g., nausea diarrhea reaching death critical cases. Thus, clean contaminants, improve fertility agricultural production, alternatives chemical must developed. Therefore, using beneficial microbes found plant-associated microorganisms offers an effective strategy alleviate some these challenges, improving fertility, yield, protecting plants stress conditions. Through synergistic interactions, synthetic consortium seeks stability microbial communities. this review, consortia their potential were discussed.
