The Plant and Soil Science doctoral program mandates 60 graduate credit hours post-bachelor's degree plus 12 dissertation credits, summing to 72 total hours. Students can specialize in areas including crop protection, crop science, fibers and biopolymers, horticulture, or soil science, with their chosen specialization declared during preliminary exams. Should admission exams identify gaps in foundational knowledge, the graduate faculty may assign additional preparatory coursework. The advisory committee guides language requirements and supplementary science coursework. Ph.D. candidates must complete comprehensive written and oral exams administered by their graduate committee, assessing their specialization expertise, interdisciplinary knowledge, scientific methodology comprehension, and scholarly communication skills.
