Soil health is crucial for global food production in the context of an ever-growing population. Microbiomes, a combination microorganisms and their activities, play pivotal role by biodegrading contaminants, maintaining soil structure, controlling nutrients' cycles, regulating plant responses to biotic abiotic stresses. Microbiome-based solutions along soil-plant continuum, scaling up from laboratory experiments field applications, hold promise enhancing agricultural sustainability harnessing power microbial consortia. Synthetic communities, i.e., selected consortia, are designed perform specific functions. In contrast, natural communities leverage indigenous populations that adapted local conditions, promoting ecosystem resilience, reducing reliance on external inputs. The identification indicators requires holistic approach. It fundamental current understanding status providing comprehensive assessment sustainable land management practices conservation efforts.
