B.S. (Magna), Plant Science, Rutgers the State University of NJ, 1978

Research
In the arid areas of the Pacific Northwest, soil management means knowing about water, about plants, and, of course, about soil.  Dr. Davenport’s research focuses on an array of projects designed to understand soil variability and how to manage water and nutrients for economically sustainable, environmentally friendly agricultural production.

Juice Grapes

  • Investigations into causes of Concord Replant Disorder
  • Evaluation of Sidrophores and Concord Chlorosis

Wine Grapes

  • Irrigation water management on juice and wine grapes
  • Soil vs Foliar P supplements in P deficient and virus affected grapevines

Soil Fertility Evaluation

  • Blueberry soil chemistry management
