Biofertilizer Technology

Description

Biofertilizers are seen as an important alternative technology, since the negative externalities of chemical fertilizers have become well known. Biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Biofertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth- promoting substances. Biofertilizers can be expected to reduce the use of chemical fertilizers and pesticides. This book provides the view of immense potential of biofertilizers as a supplementary nutrient source for the crops and covers all major types of bacterial fertilizers. Importance of nitrogen fixation and major utilities of fertilizers in agro-based industries are given. The major contents of this book is crop response to biofertilizers, nitrogen fixation, phosphate solubilising microorganisms, application and evaluation techniques, biogas production, production, quality control, and future research planning of biofertilizers. This book will be of immense use and interest to consultants, researchers, libraries, and entrepreneurs, manufacturers of biofertilizers and for those who wants to venture in to this field
