This textbook is designed as a general course in farm structures for junior and senior students in agricultural mechanization or related curricula. In this revised edition, authors James Lindley and James Whitaker provide greater emphasis on the biological aspects of agricultural structures and the importance of environmental control considerations. Table material and standard practice designs are included along with a significant amount of data required for design parameters. This book is organized in three parts: farm building construction, environmental control of agricultural buildings, and housing systems.
