Synopsis This handbook presents in-depth and innovative research on microbial biofertilizers as an alternative to chemical fertilizers and pesticides. It is a self-contained book on almost all microbial biofertilizer agents ranging from bacterial biofertilizers agents ranging from bacterial and cyanobacterial to fungal species. Handbook of Microbial Biofertilizers is indeed a forward-looking publication which encompasses almost all emerging trends in production and usage of biological fertilizers, their taxonomy, environmental improvement by them, inoculum production, and IPNM. The book also provides access to numerous case studies with specific regional examples where this technology has been successfully applied. It is indispensable for biotechnologists, microbiologists, botanists, farmers, industrialists dealing with production of microbial fertilizers, environmentalists and others, including students who are interested in the subject.  This first-of-its kind handbook provides in-depth coverage of all major microbial biofertilizers (rhizobia, arbuscular mycorrhizal fungi, and cynobacteria), as well as new ad emerging growth promoters (endophytes). It examines the role of microbes in growth promotion, bioprotectors, and bioremediators, and presents protocols and practical strategies for using microbes in sustainable agriculture. Charts, tables, and figures make complex information easy to access and understand.
