The soil-plant interface, particularly within the rhizosphere, is a dynamic zone crucial for plant health and growth. The rhizosphere is the narrow region of soil influenced by root secretions and associated soil microorganisms. This interface facilitates nutrient exchange between plants and microbes, enhancing nutrient availability and uptake. Root exudates, such as sugars, amino acids, and organic acids, attract and sustain diverse microbial communities, including bacteria, fungi, and archaea. These microorganisms perform essential functions, including nitrogen fixation, phosphate solubilization, and the production of growth-promoting substances. Additionally, they can protect plants from pathogens through competitive exclusion and the production of antimicrobial compounds. The interactions at the soil-plant interface are complex and symbiotic, significantly impacting plant health, soil fertility, and ecosystem sustainability. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of soil-plant interface. It elucidates the prospective developments with respect to this field. It will help the readers in keeping pace with the rapid changes in this field.
