A biofertilizer is a substance which makes use of living microorganisms to fertile the soil. When a
biofertilizer is applied to seed, plant surfaces, or soil, it colonizes the rhizosphere or the interior of the
plant and promotes growth by increasing the reserve of primary nutrients and growth stimulants to the
host plant. The exaggerated use of synthetic fertilizers and pesticides causes substantial harm to the soil
and environment. Although, it is not possible to completely replace synthetic fertilizers as they provide
nitrogen (N), phosphorous (P), potassium (K) and other essential nutrients to plants, but the use of
biofertilizers along with synthetic fertilizers can help to maintain soil fertility for enhanced crop
production. This second volume of the series principally deals with the biofertilizers. The articles on
preparation and uses of biofertilizers, their role in crop production, biofilmed biofertilizers and biogenic
waste compost biofertilizers showcase the growing importance of biofertilizers in agriculture sector. The
ethical issue of use of bacteria in agriculture is also raised in one article, as the opinion is still divided on
this subject. Several case studies on cultivation of rice have been included in this volume. The 25 articles
of this volume are authored by 67 senior academicians, researchers and experienced industry
professionals from different parts of the world. The publishers do hope that this scholarly series will
prove to be a valuable resource to students, researchers, academicians and industry professionals
involved in this vast field.
