Agricultural
Engineering Agricultural engineering means the application of engineering knowledge
to agriculture. The agricultural engineer must understand that there are basic
differences between agriculture and other industries. The biological factor is
an important one in engineering application, and the engineer must know well
the basic principles and practices of agriculture. Changes in agricultural practices often need to make a machine adaptable
or to increase its effectiveness. Processing equipment may also need changes to
harvest crops mechanically, for the quality of yield of a crop may sometimes be
reduced by the use of an improper machine. Most field operations are seasonable in nature often with only a short
period of time in which to do the job. Therefore field machinery in many cases
has a low annual duty (i. e. very few hours of operation per year). The field of farm machinery design gives greater opportunity to an
engineer than any other field of engineering. Farm machines must work where the
temperature may be above Not only agricultural engineers in the field of mechanization are in
demand on the farm today.
Electricians, i. e. agricultural engineers capable of designing, operating,
controlling and adapting any form of electric energy to farm needs are wanted
by modem agriculture. As is known, electric power has become the main source of energy in
agricultural production and its sphere of application is ever increasing. For example, it is a most reasonable source of mechanical power for some
kinds of equipment such as electric motors which are very suited for farm jobs
because of their automatic control, long life, compact construction, ability to
run in cold or hot weather, etc. All kinds of equipment for handling milk, such as milking machines, milk
coolers, water heaters and others are also operated by electricity. The great effects of various types of radiation on seeds, plants,
insects, and animals have been studied and are well known today. Those are but
a few examples of electric power application on the farm which a modern
agricultural engineer must work with.
