One of the current problems in crop production is increased dependency on costly imported inputs. The limited availability and imbalance use of chemical fertilizers in developing countries has led to stagnation or declining trend in soil fertility and crop yields. A huge amount of various bioresources are generated as byproducts of farm and industry, and their disposal is becoming problematic in developing countries. These bioresources if, managed properly, have tremendous potential to supply plant nutrients. The present book entitled “Bioresources for Sustainable Plant Nutrient Management” embodies concise yet comprehensive information on various potential bioresources such as biofetilizers, industrial and farm wastes, crop residues etc. focussing on fundamentals and applications in achieving sustainability in crop production and soil health. Emphasis has been given on current developments, technologies and future outlook in the area. The chapters of the book have been contributed by eminent scientists engaged in basic and applied research in this area. It is hoped that the book will be very useful to the teachers and undergraduate and post graduate students in Soil Science, Agronomy, Organic Farming and related disciplines, scientists engaged in soil management research, extension workers and planners in developing strategies for sustainable plant nutrition management and clean environment.
