Precision agriculture technologies have developed over the last three decades to aid plant agriculture. This book reviews what has happened in the past, what the cur rent situation is, and predicts what the future may hold for these technologies. Top experts who have contributed to the development of precision agriculture provide the information. Agriculture must provide an ever-increasing amount of quality food, fiber, feed, and fuel for humankind. And it must do this in a manner that is environmentally, economically, and sociopolitically sustainable.
