Students are encouraged to take courses that provide a broad background in biological and physical sciences in addition to training in specialized areas. The doctoral program aims to provide a high quality crop and soil science experience to equip students with the skills necessary for research, teaching, and extension, or other agriculture-related positions that require the Doctor of Philosophy degree. The Department of Plant, Soil and Microbial Sciences required all graduate students to participate in a meaningful teaching or extension experience and to exhibit proficiency in both writing and general presentation skills as a part of their graduate programs.
