This event is a follow-up to Farrish’s popular October webinar on the physical properties of soils. The second talk focuses on their chemical properties, such as the availability of essential plant nutrients, pH, and salinity.

Farrish, a soils scientist and professor emeritus at Stephen F. Austin State University in Texas, has a litany of awards and honors for teaching and research. Among them, he was named Regents Professor and Arnold Distinguished Professor of Forest Soils and Environmental Science at Austin State, and Outstanding Researcher at the Louisiana Tech College of Life Sciences.
Farrish earned BS and MS degrees in forestry at Michigan Technological University and a PhD from the University of Minnesota.
He and his wife, Teresa, are both members of Keweenaw Wild Ones.
