DEGREES:

  • B.S., Agronomy, University of Wisconsin-River Falls, 1971
  • M.S., Crop Physiology, University of Arizona, 1973
  • PhD., Crop Physiology, University of Missouri, 1976

RESEARCH INTERESTS:

Crop physiology; crop development and growth; nitrogen, tillage, and residue management interactions with crop growth; ramifications of using crop residues for biomass ethanol production.

MAJOR PROJECT ACTIVITIES:

Developing crop and soil management practices that improve the efficiency of use of nitrogen, and other resources, through acquisition of knowledge of crop response to interactions of the environment and management practices.
