Faculty and students examining the characteristics of a soil pit.

Admissions

All Graduate School students must utilize the Graduate Student Portal in MyUW to add, change, or discontinue any doctoral minor. To apply to this minor, log in to MyUW, click on Graduate Student Portal, and then click on Add/Change Programs. Select the information for the doctoral minor for which you are applying.

Requirements

A doctoral minor in Soil Science shall consist of a minimum of 9-credits of SOIL SCI courses with a "Grad 50%" attribute. One credit of graduate seminar, SOIL SCI 728, may be applied towards the 9-credit minimum. A minor advisor from the Department of Soil Science must serve in the student’s graduate committee and approve the courses taken to complete the minor. Please return the signed form to Soil Science Graduate Coordinator (see contact information box).

Dr. Thea Whitman

Soil Ecology, Microbiology, and Biogeochemistry: Soil microbial ecology; organic matter decomposition and carbon stabilization; global environmental change; stable isotopes; linking functional significance of microbial communities with ecosystem processes; fire effects on soil carbon and microbes; management and policy.

Dr. Xia Zhu-Barker

Soil Biogeochemistry, Land Management, and Environmental Sustainability:  Nitrogen and carbon biogeochemical cycles; greenhouse gas and air pollutant emissions; nitrate leaching and runoff; innovative manure and nutrient utilization; composting; climate change mitigation and adaptation; ecosystem services and carbon markets; dairy environmental sustainability; novel methods in isotopic techniques; mechanistic exploration of soil-plant-microbe interactions; process-based modelling. The specific research topics include:

  • Microbial and abiotic processes involved in the production and consumption of nitrogen and carbon gases (N2O, NOX, NH3, CO2, CH4)
  • Land management practices (e.g., compost, fertilizer, cover crops, irrigation, and tillage) that change soil health, nitrogen use efficiency, crop productivity, nitrogen losses, carbon turnover.
  • Process oriented modelling of carbon/nitrogen turnover in agricultural ecosystems.
  • Environmental changes on the sustainability and resilience of agricultural ecosystems especially dairy production systems.
