Book Description
Comprised of three sections, this covers the nutrient dynamics and productivity of global agroecosystems. It focuses on the major aspects that make up agroecosystems, such as soils, climate, crops, nutrient dynamics, and productivity. It introduces agroeocsystems and describes global soil types that support vast crop belts, then deals with the principles that drive crop growth, nutrient dynamics and ecosystematic functions within any agroecosystem. It also details the influence of agronomic practices and factors such as soil microbes, organic matter, crop genetic nature, irrigation, weeds, and cropping systems that affect productivity of agroecosystems.

Book Description
Evolution of the Alabama Agroecosystem describes aspects of food and fiber production from prehistoric to modern times. Using information and perspectives from both the "hard" sciences (geology, biology) and the "soft" science (sociology, history, economics, politics), it traces agriculture's evolution from its appearance in the Old World to its establishment in the New World. It discusses how agricultural practices originating in Europe, Asia and Africa determined the path agriculture followed as it developed in the Americas. The book focuses on changes in US and Alabama agriculture since the early nineteenth century and the effects that increased government involvement have had on the country's agricultural development. Material presented explains why agriculture in Alabama and much of the South remains only marginally competitive compared to many other states, the role that limited agricultural competitiveness played in the slower rate of economic development in the South in general, and how those limiting factors ensure that agricultural development in Alabama and the South will continue to keep up but never catch up.

Book Description
Maize is among the most widely spread and widely used crops of the world, used for cereals for over 4 billion humans, as food for farm animals, and as a source material for biofuel production. Yet there are relatively few books on the cropping system of this important crop. This book, Maize Agroecosystem, is a concise treatise dealing with agronomy, soil fertility, and productivity of maize. The information is global in nature and considers recent developments in all maize cropping belts. The "global maize agroecosystem" is a conglomerate of several "maize cropping belts" that flourish on different continents. The impact of nutrient management on the productivity of maize agroecosystems is the main focus of this book. The book includes the history of maize growing, the kinds of soil needed, nutrient dynamics, the use of soil organic matter, the physiology and genetics of maize, and integrated nutrient management. It presents comprehensive knowledge regarding the physicochemical dynamics of the three major nutrients: nitrogen, phosphorus, and potassium. Also covered is how fertilizers impinge on soils of maize farms and their impact on soil and groundwater quality. The impact of crop genotype on soil nutrient dynamics and productivity is also highlighted. The information provided here will be highly useful to students at colleges and universities in the fields of agricultural sciences and environmental science and ecology, and the book also functions as valuable resource for researchers and professors in crop science. Several figures and tables are included that describe and summarize the impact of various agronomic/fertilizer management procedures on crop productivity.

Book Description
Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. The Ecology of Agroecosystems highlights a collection of alternative agricultural methodologies and philosophies and provides an interdisciplinary approach that bridges the sociopolitical and historical context of agriculture. It includes the technical issues in a serious and ecological fashion and captures the complex merging of ecology, agriculture, politics and economics in both a historical and contemporary context. Readers will learn not only about the ethical and moral elements related to producing food of questionable quality while possibly impairing the environment, but also about the soil chemistry involved.

Book Description
"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.

Book Description
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. Agricultural Drones: A Peaceful Pursuit provides a wealth of information on drone usage in agriculture. The book discusses the advanced sensors and imaging capabilities of drones that give farmers new ways to increase yields and reduce crop damage. An introductory chapter provides historical data, with details about various models of drones as well as the most recent and popular agricultural drones in usage. The book goes onto look at such topics as the use of drones for soil fertility, production agronomy, irrigation, weed control, pest and disease control, grain yield forecasting, and economic advantages from drone use. This timely and useful volume will be a valuable resource for faculty, agricultural extension officers, and farmers and farm consultancy agencies. This book would also serve as an excellent textbook for students in agriculture, engineering, geography, etc. Key features: • outlines the advantages of using drones in agriculture, such as for the management of soil fertility, the study of natural resources and vegetation, the maintenance of adequate irrigation, and the control of weeds and pests • covers the economic advantages of using drones in agriculture • examines the regulatory aspects of agricultural drones • provides actual examples of drone usage in agriculture
