Agricultural engineering is the engineering discipline that applies engineering science and technology to agricultural production and processing. Agricultural engineering combines the disciplines of animal biology, plant biology, and mechanical, civil, electrical and chemical engineering principles with a knowledge of agricultural principles.
- design of agricultural machinery, equipment, and agricultural structures
- internal combustion engines as applied to agricultural machinery
- agricultural resource management (including land use and water use)
- water management, conservation, and storage for crop irrigation and livestock production
- surveying and land profiling
- climatology and atmospheric science
- soil management and conservation, including erosion and erosion control
- seeding, tillage, harvesting, and processing of crops
- livestock production, including poultry, fish, and dairy animals
- waste management, including animal waste, agricultural residues, and fertilizer runoff
- food engineering and the processing of agricultural products
- basic principles of circuit analysis, as applied to electrical motors
- physical and chemical properties of materials used in, or produced by, agricultural production
- bioresource engineering, which uses machines on the molecular level to help the environment.
- Design of experiments related to crop and animal production
