Environmental Biophysics Lectures
During a recent semester at Washington State University, a film crew recorded all of the lectures given in the Environmental Biophysics course. The videos from each Environmental Biophysics lecture are posted here for your viewing and educational pleasure.

Take our Soil Moisture Master Class
Six short videos teach you everything you need to know about soil water content and soil water potential—and why you should measure them together. Plus, master the basics of soil hydraulic conductivity.
I want to apply your work towards my forest regeneration projects. My goal is to grow one of the largest white pines in Michigan!
That’s so exciting! Let us know how it goes!
