Agricultural engineering combines the disciplines of electrical, mechanical, civil and chemical engineering and applies them to agricultural processing and production. An agricultural engineer has the goal of increasing the sustainability and efficiency of agricultural techniques.

Australia has a subsidized higher education for students pursuing the undergraduate degrees. They also give loan and grants for the post graduate students. Higher learning starts at undergraduate degree level to a doctoral degree offered in any field of study.

Graduate diplomas are typically not offered in the United States. The American equivalent of a diploma is referred to as a professional certification. Each university has a different set of requirements for admission, so students should perform in-depth research on programs before applying.
