The courses offered in this department are intended to give a broad
view of farm chemistry useful to the general agricultural student, and to
develop men fitted for instructional or experimental work in the various
fields of chemical activity applied to agriculture. Courses 120 and 122
are for students desiring a more detailed knowledge of the special subjects
treated and are preliminary to greater specialization. These courses should
be preceded or accompanied by work in biology and organic chemistry.
Physiology and bacteriology are desired prerequisites. All other advanced
courses in this department are open to undergraduates and graduates who
have had the necessary preliminary training.
