Abstract

The contemporary situation of climate change and population burst has rendered enormous pressure on food security. Sustainable management of ecosystem and food production enhancement must take into account the maintenance and augmentation of soil fertility and productivity. In this context, rhizospheric microbiome has an indispensable role to play. The rhizosphere is the area of soil where plant roots are active, harboring diverse microbial populations being the hot spot for microbial activities. Microbes are suggestively a biological indicator to determine rhizospheric health. They are pivotal for soil and plant health, thus helping plants to mitigate biotic and abiotic stresses as upcoming strategy to maintain health in a sustainable way. On the other hand, conventional agricultural approaches and non-judicious use of agrochemicals can potentially bring antagonistic changes in rhizospheric microbiomes. This alteration is further aggravated with climate change, pressurizing soil microbiome and interfering with ecological processes in terms of diversity, structure, and functions, which are associated with a loss in soil biodiversity and soil organic matter. Increasing urbanization has emerged as a major source of soil degradation. Protecting and restoring soil microbiome has both economic and environmental benefits. A combination of soil amendments, genetic modification, and targeted microbiome engineering can be beneficial in reducing additional input of agrochemicals. In recent decades, incorporation of molecular techniques has refined our understanding of microbial ecology that could be crucial in drafting future strategies. This chapter summarizes the current knowledge related to rhizospheric microbiome composition and its functions in soil and plant health for sustainable production system, besides reviewing the strategies to enhance its own overall health.
