"The agricultural sky" is a dominant natural entity that has influenced, interacted with, and guided the evolution of crops, farming practices, and cropping systems. The sky—and all its components—above and near agricultural areas is an important aspect of an agricultural enterprise—as important as soils, water, and crop species. The blue sky above crops that is seemingly clear, tranquil or sometimes filled with clouds, is really a repository of a large number of gases, mineral or organic particulate matter, dust, mist, turbulent wind, innumerable species of micro-organisms, tiny biotic flora/fauna, seeds, insects, etc. The agrarian sky supports complex interactions of biotic and abiotic aspects with perhaps immediate and/or delayed influence on crops sown on the ground. This volume helps us to better understand the importance of the sky above crop fields, with the goal to encourage revolutionary agronomic procedures that lead to higher yield. It is a comprehensive treatise on the agriculture sky, covering basic definitions, limits, and explanations about atmospheric layers like troposphere, stratosphere, and the phyllosphere. The volume addresses the nutrient dynamics in the sky and their relevance to crop productivity. It looks at both natural biotic and manmade abiotic factors in the sky and how they affect what goes on below, such as from dust storms, at cloudy and/or windy locations, and from high-altitude jet streams. The author discusses wind and solar power generation in the agrarian sky and explores aeroponics to revolutionize crop production. The volume delves into several types of aerial robots, employing AI and other technology, to provide aerial spectral data that are capable of analyzing procedures, soil conditions, irrigation, insect pests, weed detection, herbicide application, soil fertility, and much more. The book includes examples from the North American Great Plains, Pampas of Argentina, Sahelian production zones of West Africa, Indo-Gangetic Plains, etc. This eye-opening book, The Agricultural Sky: A Concept to Revolutionize Farming, will be useful to students and professors in universities as well as to researchers in industry dealing with aerial aspects of farming.

This important volume provides a plethora of information on aerial vehicles and their possible roles in revolutionizing agricultural procedures through spectral analysis of terrains, soils, crops, water resources, diseases, floods, drought, and farm activities. There are several semi-autonomous and autonomous (robotic) aerial vehicles that are examined for their efficiency in offering detailed spectral data about agrarian regions and individual farms. Among them, small drone aircrafts such as fixed-winged and copter models have already caught the imagination of farmers. They are spreading fast in every nook and corner of the farm world. However, there are many more aerial robots that are utilized in greater detail during farming. In this volume, the focus is on aerial vehicles such as parafoils, blimps, aerostats, and kites, and how they are being evaluated for use in experimental farms and fields. A few aerial vehicles, such as robotic parafoils, have been adopted to procure aerial spectral data and visual imagery to aid agronomic procedures. These and other aerial robots are expected to change and improve the use of the sky in agricultural endeavors and the way we conduct agronomic procedures in the very near future. This volume is a timely resource for agricultural researchers, professors and students, and the general public who are interested in aerial vehicles.

Agricultural drones are expected to revolutionize the way we conduct agronomic procedures and maintain natural vegetation on earth. This book explores the increasing importance of the role of aerial robots in managing agricultural farms and natural resources.
