University of North Dakota

What you'll study

This PhD is built around original research and advanced coursework that together develop expertise in soil processes, measurement and management. Students tailor a programme of study in consultation with a supervisory committee; typical course themes include soil physics, soil chemistry, soil microbiology and biogeochemistry, pedology, hydropedology, land–atmosphere exchange, and soil-plant interactions.

• Core research training: experimental design, quantitative statistics, advanced analytical methods for soil and water, and scientific communication.
• Typical taught modules: Soil Physics and Hydrology; Soil Chemistry and Nutrient Cycling; Soil Microbial Ecology; Pedology and Soil Classification; Advanced Soil Fertility and Plant Nutrition; Remote Sensing and GIS for Soil Studies; Soil Contamination and Remediation.
• Methods and tools: field and laboratory techniques (core sampling, lysimeters, sensor networks, spectral and chemical analyses), molecular biology approaches for microbial community analysis, and digital soil mapping and modelling.
• Structure: students complete advanced coursework, pass a qualifying or comprehensive examination, and undertake an original research project culminating in a doctoral dissertation and defence. Regular seminars and departmental research meetings support professional development.
• Research focus areas typically available: cold-region and prairie soils, wetland and riparian soil processes, soil carbon cycling and sequestration, nutrient management for sustainable agriculture, soil–water interactions, and impacts of land use and climate change on soil function.

Entry requirements

Applicants are expected to hold a relevant master’s degree (or equivalent) with a substantial research component, such as a thesis, in soil science, agronomy, environmental science, ecology, geology or a closely related discipline. Exceptional applicants with a strong bachelor’s degree and significant research experience may be considered for direct entry to PhD study in some cases.

• Academic record: a strong graduate-level academic record demonstrating preparation for advanced study and independent research.
• Research experience: evidence of prior research ability (for example, a master’s thesis, publications, technical reports, or significant project work) is important.
• Supporting documents: a research statement or proposal outlining potential doctoral research interests, a curriculum vitae, and academic transcripts.
• References: at least two academic references who can comment on research potential and readiness for doctoral study.
• English language: for international applicants, proof of English proficiency where required by university regulations.
• Supervision match: admission typically requires identification of a potential faculty supervisor whose research interests align with the candidate’s proposed project.

Career prospects

Graduates of the PhD in Soil Sciences pursue a wide range of careers in academia, government, industry and non-government organisations. The programme prepares graduates for research and leadership roles that require advanced analytical skills and subject-matter expertise.

• Academic and research careers: university faculty positions, postdoctoral research, and research scientist roles in public or private research institutions.
• Government and public sector: soil and water conservation agencies, environmental protection authorities, national agricultural research services, and natural resource management departments.
• Industry and consulting: environmental and agricultural consulting firms, precision agriculture companies, carbon accounting and soil carbon project design, remediation and land-redevelopment specialists.
• Non-governmental and international roles: environmental NGOs, international development agencies and organisations focused on sustainable land management, food security and climate mitigation.

Why study at University of North Dakota

Studying soil science at the University of North Dakota provides the opportunity to work on soils characteristic of cold and continental climates, including prairie, wetland and riparian systems. UND’s research environment emphasises interdisciplinary approaches that link soil science with hydrology, ecology, agriculture and climate science, enabling students to address regionally relevant and globally significant questions.

Doctoral students benefit from access to field sites across diverse landscapes, laboratory facilities for chemical and biological analyses, and collaborations with regional agencies and agricultural stakeholders. The department supports professional development through seminars, grant-writing workshops and opportunities to participate in teaching and extension activities.
