These three volumes present essential engineering technologies most often used for design and evaluation of the best practices in agricultural production and postharvest processing operations. The choices, requirements, procedures, and expected performances are expertly supported with equations, data tables, illustrations, charts, graphs, and data conversion factors for SI units. Written by highly qualified and experienced agricultural engineers, the chap-ters emphasize field machines and practices, irrigation engineering, drainage and erosion control, and waste management. Also in-cluded is information on electrical systems and electric motors, de-sign of structures, ventilation and lighting systems, and livestock and poultry production. This volume is especially written for engi-neers of all types, agricultural scientists, extension specialists, ag-industry-managers, and engineering students. VOLUME II: SOIL AND WATER ENGINEERING
