Agricultural engineers, also sometimes known as natural resource engineers, apply engineering principles of science and technology, as well as knowledge of agricultural practices, to solve problems relating to sustainable agricultural production, the environmental impacts of intensive agriculture and the post-harvest handling of agricultural products. They manage living things and life-giving resources in such a way as to protect and preserve them by using mechanical, civil and electronic engineering skills.
They design equipment, buildings, and dams, which can utilize the environment and resources more effectively, while ensuring their renewability and sustainability. Some practise in areas such as forestry, food processing, urban and rural development, agricultural machinery design and manufacturing.
Agricultural engineers design agricultural machinery and equipment and develop methods to improve the production, processing and distribution of food and other agricultural products. They are involved in the conservation and management of energy, soil and water resources. These engineers design and use instruments to study the effects of light, humidity and temperature on plants and animals. They also design structures for crop storage and animal shelters. Some teach at universities and universities of technology.
Agricultural engineering provides challenging career opportunities in various fields such as research, consulting, development, testing, engineering surveys, management, planning, teaching and counselling.
Areas of specialization in agricultural engineering include:
Water supply and irrigation: Effective utilization of available resources is of primary importance. In this field the agricultural engineer is involved with hydrology and farm dam design; canal, pipeline and pump systems; sprinkler, drip and
micro-irrigation systems; mechanized irrigation; surface irrigation; and drainage.
Agricultural Mechanization: Agricultural machinery plays an important role in the production of food. Agricultural engineers assist producers, contractors and farmers with: tractor and other engine tests; development of new machinery; design of agricultural equipment; planning and evaluation of mechanization systems; agricultural energy research and consultation; and appropriate technology for developing areas.
Soil conservation: Agricultural engineers' civil engineering knowledge is essential for the planning and designing of: conservation and reclaiming structures; systems for the safe discharge of flood water; contour and other appropriate cultivation systems to safeguard vulnerable agricultural lands against erosion and specially adapted farming practices to enhance soil conservation.
Agricultural buildings and structures: This field includes the following: buildings for the intensive production of meat, dairy products, poultry and eggs; buildings with controlled environments such as green- and glass- houses, nurseries, and aquaculture; buildings for the storage and processing of products such as grain silos and dryers for maize, tobacco and fruit; and plastic sheeted tunnels for intensive cultivation of flowers and vegetables.
Food and fibre processing: Processing involves the preparation of commodities that are used by human beings or animals. Agricultural engineers guide entrepreneurs in the following: drying, milling, mixing, compacting, cooling, heating and liquidizing of agricultural products; handling, storage, transportation and packing systems, for example, of fruit, vegetables and meat.
Work settings vary from indoors, in modern well-equipped laboratories and offices, to outdoors at farm sites. They may also vary according to the type, size, location and financial resources of the employer.
- working outdoors
- having a variety of specialities available
- earning good money
- achieving prestige
- working outdoors in bad weather
- not always being able to solve a problem
- having to continuously study to keep up with latest developments
An agricultural engineer should:
- have aptitude for and interest in biology, including the soil, plants and animals
- have the ability to identify, analyze and solve problems
- have good oral and written communication skills
- have aptitude for computing and design
- have ability to work without supervision and accept responsibility
- be logical and practical
- be inventive and innovative
- be creative and analytical
- have general scientific interest
- be enthusiastic, have perseverance and patience with details
National Senior Certificate meeting degree requirements for a degree course
National Senior Certificate meeting diploma requirements for a diploma course
Each institution will have its own minimum entry requirements.
Compulsory Subjects: Mathematics, Physical Science
Recommended Subjects: Agricultural Sciences, Life Sciences, Engineering and Technology
Note: The engineering faculties of some universities offer support programmes to help students become self sufficient and capable of completing very demanding engineering courses. These programmes are aimed at students from communities which lack proper education facilities. Only students with matric exemption with a minimum of a D-symbol (Higher Grade) will be considered.
Degree: a four-year BSc (Eng) degree is offered by the Universities of Pretoria and Natal. As is the case with other fields in engineering, the completion of the degree and a minimum of three years' in-service training leads to registration as a professional engineer.
Diploma:?For those who want to qualify as technicians or technologists in an agricultural specialising field, CUT, UNISA and NMMU offer the N.Dip. Agricultural Management. Agriculture, Science and Technology is offered by NWU, Agriculture MTech and DTech - TUT.
- Department of Agriculture
- manufacturers of agricultural remedies and food companies
- manufacturers of farm equipment and supplies
- government and private research institutes, such as SABS and CSIR
- universities, colleges and universities of technology
- consulting firms
- agricultural control boards and unions
- agricultural co-operatives
- large farming enterprises, such as estates
- self-employment - skilled and entrepreneurial agricultural engineers can start their own consulting or manufacturing businesses
