Soil Microbiology is a field that investigates the fundamental aspects of microorganisms and their connections to agriculture, with a focus on improving soil fertility and crop yields, biodegradation of crop residues, and combating pests and diseases. A fascinating aspect of this microbiology is the study of how these tiny life forms communicate and interact with each other in the soil environment. Soil microorganisms play vital roles in the nutrient cycling that is essential to life on the planet. The book covers the syllabus of various universities, both at the undergraduate and postgraduate levels, and the information presented in the book fulfills the need. The book is clear and easy to understand, explained through various diagrams. It is believed that the publication is not only necessary for students but also for academic professionals.
