4. Interaction with other sectors

Agricultural engineering is closely linked to the following sectors:

- Plant production: agricultural engineering constitutes an extension of this sector in virtually every respect
- Plant protection: mechanical methods, application techniques
- Livestock farming: use of animal traction, intensive animal husbandry (still on only a small scale in developing countries, but extremely widespread in industrialised nations), livestock farming practices
- Irrigation: particularly supply, application and distribution of water, gravity-flow and pressure irrigation methods (sprinkling, drop irrigation)
- Agro-industry: primary products ("large-area products" such as grain and sugar), use of wastes
- Rural hydraulic engineering: correlation with plot size
- Renewable sources of energy (biomass)
- Mechanical engineering
- Mills handling cereal crops
