Doctor of Philosophy
The doctorate symbolizes the ability of the student to undertake
original research with minimal supervision and demonstrates the studentâs
ability to write a dissertation reporting the results of this research.
Eventual publication in a scholarly, refereed journal is expected of research
from the dissertation. There are no definite course requirements for the
Ph.D. degree. There is, however, a Graduate School requirement for a minimum
of 72 credit hours for a Doctoral degree. Of these 72 credit hours, 18 may
be transferred from a Masterâs degree. Note that the 72-credit-hour
requirement may be waived for students who meet all other requirements
for graduation. Most Doctoral Plans of Graduate Work contain 30 to 40
semester credit hours with about one-third of the credit hours coming from
courses taught outside of the Department of Soil Science. The Plan of
Graduate Work must contain at least one credit hour of seminar (SSC 801)
and at least two credit hours of research (SSC 893 or SSC 895). Additional
credit hours of research may be used to fulfill continuous registration
requirements but do not need to be listed on the Plan of Graduate Work.
The preliminary written and oral examinations must be completed within six
calendar years, and all degree requirements must be completed within ten
years from the date of admission to the Doctoral program. A non-credit
exit seminar is required.
