The Bachelor of Science in Agriculture (BSAg) or the Bachelor of Agriculture (BAg) is the undergraduate academic degree awarded by tertiary faculty of agriculture. The program is typically four years of study at postsecondary level. In Canada, the bachelor's degree in agriculture differs from a bachelor of science degree in that the courses focus on agriculture: for example, the student will study agricultural economics rather than economics. Like engineering or forestry, agricultural science courses are infused with practicality.
