The third edition of this book exposes the reader to a wide array of engineering principles and their application to agriculture. It presents an array of more or less independent topics to facilitate daily assessments or quizzes, and aims to enhance the students' problem solving ability. Each chapter contains objectives, worked examples and sample problems are included at the end of each chapter. This book was first published in the late 60's by AVI. It remains relevant for post secondary classes in Agricultural Engineering Technology and Agricultural Mechanics, and secondary agriculture teachers.

"This edition provides the latest technology in the design of surface, sprinkler, and microirrigation systems along with basic information about soils and current information on estimating crop water requirements. New chapters have been added on planning systems, environmental issues, efficiency and uniformity, chemigation, and use of wastewater for irrigation."--Preface

The agriculture, forestry, and fishing sectors are the cornerstone of industries that produce food, fiber, and biofuel. The National Institute for Occupational Safety and Health (NIOSH) conducts research in order to improve worker safety and health in these sectors. This National Research Council book reviews the NIOSH Agriculture, Forestry, and Fishing Program to evaluate the 1) relevance of its work to improvements in occupational safety and health and 2) the impact of research in reducing workplace illnesses and injuries. The assessment reveals that the program has made meaningful contributions to improving worker safety and health in these fields. To enhance the relevance and impact of its work and fulfill its mission, the NIOSH Agriculture, Forestry, and Fishing Program should provide national leadership, coordination of research, and activities to transfer findings, technologies, and information into practice. The program will also benefit from establishing strategic goals and implementing a comprehensive surveillance system in order to better identify and track worker populations at risk.

This book is for use in introductory courses in colleges of agriculture and in other applications requiring a problematic approach to agriculture. It is intended as a replacement for an Introduction to Agricultural Engineering by Roth, Crow, and Mahoney. Parts of the previous book have been revised and included, but some sections have been removed and new ones has been expanded to include a chapter added. Problem solving on techniques, and suggestions are incorporated throughout the example problems. The topics and treatment were selected for three reasons: (1) to acquaint students with a wide range of applications of engineering principles to agriculture, (2) to present a selection of independent but related, topics, and (3) to develop and enhance the problem solving ability of the students. Each chapter contains educational objectives, introductory material, example problems (where appropriate), and sample problems, with answers, that can be used for self-assessment. Most chapters are self-contained and can be used independently of the others. Those that are sequential are organiZed in a logical order to ensure that the knowledge and skills needed are presented in a previous chapter. As principal author I wish to express my gratitude to Dr. Lawrence O. Roth for his contributions of subject matter and gUidance. I also wish to thank Professor Earl E. Baugher for his expertise as technical editor, and my wife Marsha for her help and patience. HARRY FIELD v 1 Problem Solving OBJECTIVES 1. Be able to define problem solving.

Designed to assist in attaining a basic understanding of the nature of electricity and in developing skills in solving problems associated with applying electricity in agriculture. The first chapters lay the foundation in the basics of electricity. The second portion of the book deals with applications and devices commonly found in agricultural uses of electricity.

Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

This textbook offers a comprehensive review of tractor design fundamentals. Discussing more than hundred problems and including about six hundred international references, it offers a unique resource to advanced undergraduate and graduate students, researchers and also practical engineers, managers, test engineers, consultants and even old-timer fans. Tractors are the most important pieces of agricultural mechanization, hence a key factor of feeding the world. In order to address the educational needs of both less and more developed countries, the author included fundamentals of simple but proved designs for tractors with moderate technical levels, along with extensive information concerning modern, premium tractors. The broad technical content has been structured according to five technology levels, addressing all components. Relevant ISO standards are considered in all chapters. The book covers historical highlights, tractor project management (including cost management), traction mechanics, tires (including inflation control), belt ground drives, and ride dynamics. Further topics are: chassis design, diesel engines (with emission limits and installation instructions), all important types of transmissions, topics in machine element design, and human factors (health, safety, comfort). Moreover, the content covers tractor-implement management systems, in particular ISOBUS automation and hydraulic systems. Cumulative damage fundamentals and tractor load spectra are described and implemented for dimensioning and design verification. Fundamentals of energy efficiency are discussed for single tractor components and solutions to reduce the tractor CO2 footprint are suggested.
