Book excerpt: In this age of population explosion and depleting natural resources, this book offers new techniques to produce more from agricultural crops at a lower cost. The field of agronomy addresses this issue and interacts with the fields of agriculture, botany, and economics. Nanotechnology and nanoparticles play a role in agronomy. This book will join the techniques from both fields to construct one comprehensive book. Students of agriculture, physics, nanotechnology, and plant sciences will benefit equally from this work.
