Recent Trends in Biofertilizers comprises sixteen articles contributed by over forty distinguished academicians from India, Brazil and Egypt. These articles jointly address the broader need of increasing soil fertility through sustainable methods and practices. Biofertilizers contain a wide range of naturally chelated plant nutrients, carbohydrates, amino acids, trace elements and plant growth promoting vitamins and hormones. These components are discussed appropriately in the book. Fresh insights into biofertilizer technology, biotechnology-based biofertilizers, and other recent developments in this area are covered in depth. Discussion of the tremendous advancements made in the last decade in biofertilizer technology through development of biotic and abiotic stress tolerant microbial strains is one of the hallmark features of this book. The book also appropriately addresses the soil aspects -- nutrient index values for different types of soil have been presented. Other major highlights of the book are coverage of liquid biofertilizers; benefits of different biofertilizer efficient strains along with the constraints in the production, distribution, field and marketing; quality control and assurance aspects; and application of bioinformatics. With its coverage and emphasis, this book will be an immensely useful reference for teachers and students of undergraduate colleges, universities, and research scholars who are engaged in this aspect of research, such as agricultural microbiology, trainees in biofertilizer industry and agricultural development officers.
