A doctorate with a major in plant, soil, and environmental sciences and a concentration in environmental and soil sciences is offered under a multi-departmental doctoral program. Two departments participate – Plant Sciences and the soils faculty in Biosystems Engineering and Soil Science. Other concentrations within the plant, soil, and environmental sciences doctoral program include crop sciences, horticulture, plant breeding, plant molecular genetics, and weed science. Focus areas in the environmental and soil sciences concentration include soil and water chemistry; nutrient management; pedology, genesis and classification; environmental climatology; soil biology and biochemistry; and soil physical processes. See the Department of Biosystems Engineering and Soil Sciences graduate education website for additional information or contact a faculty member in the area of interest.

Credit Hours Required
72 credit hours beyond the Bachelor’s or
48 credit hours beyond the Master’s
- ESS 600 Doctoral Research and Dissertation, 24 credit hours
- A candidate for the doctoral degree must complete a minimum of 24 credit hours of graduate course work beyond the master’s degree, or for candidates not having a master’s degree must complete a minimum of 48 credit hours of graduate course work beyond the baccalaureate degree, 24 credit hours of which must be numbered 503 or higher.
- A minimum of 12 of the 24 credit hours, or 30 of the 48 credit hours, must be graded A-F.
- ESS 603 (1 credit hour) must be taken three times during the course of the program (total of 3 credit hours), the last of which must be in the student’s final semester before graduation. The 3 credit hours of ESS 603 can be used toward the minimum of 24-(or 48-) credit hour requirement.
- At least 9 credit hours of the student’s course work must be from outside the environmental and soil sciences concentration that are related to the students’ research area. These courses must be approved by student’s major advisor and advisory committee.
- A minimum of 6 credit hours of courses numbered 601 or higher, excluding ESS 603 , must be taken at University of Tennessee, Knoxville.
- The student and the major professor will select a minimum of three additional faculty, holding the rank of assistant professor or above, to serve on the student’s doctoral committee.
- The major professor and two committee members must be approved to direct doctoral research by the Graduate Council.
- At least one member of the committee must be from outside the department. The doctoral committee must be formalized by the end of the second semester of graduate study.
- An approved program of study must be submitted by the end of the second semester of graduate study.
- Satisfactory preparation of a written dissertation proposal and an oral defense to the student’s committee are required. These must be completed during the first two semesters of graduate study and before enrollment in ESS 600.
- Both written and oral sections of the comprehensive examination must be passed. The candidate will be tested on his/her knowledge of the proposed dissertation and related fields. The student is expected to be conversant in the wide area of soil and environmental sciences.
- Preparation of a written dissertation and its oral defense to the student’s doctoral committee are required.
