Dr. David Lobb

Dr. David A. Lobb joined the Department of Soil Science in January 1999. His training includes a B.Sc. in Biophysical Systems from the University of Toronto (1987), a M.Sc. (1991), and a Ph.D. (1998) in Soil Science from the University of Guelph.

Dr. Lobb is a Professor in the Department of Soil Science, and Senior Research Chair for the Watershed Systems Research Program (WSRP). He is also contributing to the University's Create H2O Program. Dr. Lobb's research focuses on biophysical processes within landscapes, particularly soil movement by tillage and tillage erosion. His lab is the largest in Canada and the second largest in the world for the assessment of soil erosion and sedimentation using radionuclides and other methods. This area of research is known as fingerprinting.

Current Research Interests:

  • Soil redistribution within landscapes and its impact on biophysical processes that affect agriculture and the environment
  • Tillage systems and their impacts on biophysical processes that affect agriculture and the environment
  • Agri-environmental indicators
  • Soil-landscape variability: causes, characterization and management (precision-farming)
