The book ?Microbial Empowerment in Agriculture: A Key to Sustainability and Crop Productivity? is a compilation of works from eminent scholars who have worked on various microbes of agricultural significance. Chapters of the book have addressed different microbes that are used in agriculture for ensuring environmental sustainability and increasing crop productivity. Recent trends in the field of agricultural microbiology related to fixing atmospheric nitrogen (bacterial and cyanobacterial) and mobilization of various other nutrients in soil (fungal and bacterial) are covered in various chapters of the book independently. Moreover, microbes used for management of fungal, bacterial and nematode problems in agricultural crops are also included in the book. Microbes used for remediation of toxic metals in agricultural fields are also part of the book. Modern trends such as microbial genes and genomics were also included in the book to highlight some recent perspectives. In general, the book covers nearly all agriculturally significant microbes that are currently being used to increase crop productivity in a sustainable manner with a modern outlook.
