Plant, Soil, and Environmental Sciences

Return to {$returnto_text} Return to: Graduate Programs and Certificates

The Department of Plant, Soil, and Environmental Sciences is a multidisciplinary department whose research and graduate training programs emphasize the biogeochemistry and sustain-ability of agricultural, forested and wetland ecosystems. Areas of emphasis for graduate work include nutrient dynamics in agricultural and forest ecosystems, soil chemistry and plant nutrition, soil microbiology, crop physiology, diversified cropping systems, weed ecology and management, and plant pathology. Thesis problems may be developed in a wide range of subject areas. For example, graduate work may be conducted to determine the effects of climate change and land use on nutrient fluxes in forested watersheds. The department plays a strong role in many of The University of Maine’s nationally-recognized programs, such as the Sustainable Agriculture program, the Potato Ecosystem Project, Bear Brook Watershed in Maine, the Water Research Institute, and Acadia National Park programs. Facilities are available for laboratory, greenhouse, farm field, forest stand, and watershed-scale research.

Graduate students working in the Department of Plant, Soil, and Environmental Sciences can earn the Master of Science degree through programs in Plant, Soil, and Environmental Sciences; Ecology and Environmental Sciences; and Resource Utilization. The Doctor of Philosophy degree can be pursued through programs in Ecology and Environmental Sciences, Forest Resources, Plant Biology, and Biological Sciences. Several of our faculty have cooperating appointments in other departments, providing some of our students with additional degree options. Prospective students should contact faculty who might serve as their supervisors to discuss which degree option is appropriate for their particular interests and goals. Applications for admission should be obtained from the Graduate School (5782 Winslow Hall, University of Maine, Orono, ME 04469-5782, U.S.A.; Telephone 207-581-3218; Fax 207-581-3232; e-mail graduate@maine.edu; world-wide web www.umaine.edu/graduate and, when completed, sent to The University of Maine Graduate School. Applications should indicate both the graduate program and the department the applicant seeks to enter.

Graduate training programs in the department are built from foundations in soil science, agronomy, plant physiology, ecology, micro-biology, plant pathology, and statistics. Prospective graduate students should have completed course work in chemistry, mathematics, and biology, and in subject matter areas closely related to their interests and those of their advisor.

A limited number of half-time departmental assistantships, involving both teaching and research, are available on a competitive basis. Additional opportunities for assistantship support are associated with faculty working on extramural grants and research contracts. Prospective graduate students are urged to contact faculty who might serve as supervisors for their graduate degree work to determine the availability of assistantship support. Additional information concerning graduate studies in the Department of Plant, Soil, and Environmental Sciences may be obtained from Dr. Tsutomu Ohno (Graduate Coordinator), Ms. Mary Fernandez (Student Coordinator) (Mary_Fernandez@umit.maine.edu), or from the World-Wide Web (www.umaine.edu/pse).
