Microbial Inoculants: Soil Dynamics and Nutrient Bioavailability is an essential volume in the Plant and Soil Microbiome series. This book delves into the foundational and contemporary details regarding the use of microbial inoculants, which are living organisms like fungi, bacteria, and microalgae, sourced from soil, plants, water, and organic materials. Acting as biostimulants or biocontrol agents, these inoculants offer an environmentally-friendly alternative to synthetic fertilizers and pesticides, playing a crucial role in soil conservation, plant health, and crop yield enhancement. Apart from exploring the nexus between plant and soil, the book also discusses the range of applications of microbial inoculants in agricultural and environmental practices. It provides insights into how these microorganisms contribute to sustainable farming by enhancing nutrient bioavailability and protecting crops from diseases, thus promoting better yield and overall plant vitality. This volume is a valuable resource for those interested in advancing agricultural techniques through the utilization of natural, biotic solutions.
