There is general belief and admission that important, innovative, and novel ideas emerge over a cup of tea or a glass of beer and the weather must be congenial and most suitable for materializations of original ideas. The genesis of this book underlines the concept developed in 2015. Technological advances and sociological changes are such that Science demands evolution. We believe that one reason for publishing of ideas is broadening one’s view, through the examination of a text of wide and extensive coverage, nurtures one’s capacity for learning and reflection. The study of microorganisms has become a valuable science in the last 100 years as it has provided the means to control a number of infectious diseases. In this direction, nanotechnology has emerged as a potential candidate. The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanoparticles are gaining attention due to their low cost, simplicity, and ecofriendly nature. In this volume entitled “Nanoscience and Plant–Soil Systems,” the editors have accumulated various advanced approaches for studying the different soil microorganisms for the benefit of humankind. Currently, world agriculture scientists face a wide spectrum of challenges including climate change, urbanization, and environmental issues: accumulation of insecticides and pesticides, decay in soil organic matter, and sustainable use of natural resources. These challenges are going to be further intensified due to increase in food demand. Nanotechnology has significant benefits
