About Dr. Chip Appel
I earned a B.S. in Biochemistry (Cal Poly, 1995), an M.S. in Soil Science (Cal Poly, 1998), and a Ph.D. in Soil Chemistry (University of Florida, 2001). In between these degrees I lived in France for two years in order to learn and perfect my French language skills. I am a member of the Soil Science Society of America and the American Society of Agronomy and am a Certified Professional Soil Scientist (CPSS). My favorite parts of working at Cal Poly are teaching and teaching related activities. I perform research in soil chemistry, tropical soil chemistry/management, trace element biogeochemistry, vineyard soil management/fertility, environmental soil management, and soil nutrition. I consult regularly on vineyard soil fertility for Kesselring Vineyard Consulting Services, Inc. When I am not at Cal Poly, I really enjoy being with my family and surfing.
