Climate change has a major impact on the global agricultural production as it influences crop productivity, soil stability and dynamics of the ecosystem. In this context, the crop microbiome has emerged as an important biological factor for enhancing agricultural sustainability and climate resilience. This review examines recent field and experimental studies on sustainable farming practices that utilise microbiome dynamics to develop climate-smart farming systems. It outlines the importance of essential processes such as nutrient cycling, disease resistance, stress tolerance and soil carbon stabilisation are impacted by plant-associated microbiomes in the rhizosphere, endosphere and phyllosphere. Farming practices such as conservation tillage, intercropping, cover cropping, irrigation management, organic amendments
and integrated nutrient management (INM) have considerable impacts on microbial diversity, structure and function. These practices promote the healthy populations of microbes, with changes in the pattern of root exudation and soil condition, which enhance the health of the soil. Biological nitrogen fixation, phosphorus solubilisation, hormone regulation, induced systemic resistance (ISR) and osmotic regulation processes are microbiome mediated, leading to increased crop productivity and adaptation to environmental changes. Moreover, microbiome-driven function enhances plant defence, increase fertiliser and water use efficiency (WUE) and contribute to greenhouse gas (GHG) mitigation and carbon sequestration. Sustainable farming practices can enhance the resilience of agroecosystems and decrease
dependence on synthetic inputs through beneficial crop microbiome interactions. Understanding and managing crop microbiome dynamics offers a promising approach for achieving climate-smart and sustainably intensified agricultural systems.
