Soil! What it is and How it Works for Trees

Date: January 18, 2017
Location: University of Washington, Center for Urban Horticulture, Douglas Classroom , Seattle, WA, UNITED STATES
Organizer: Pacific Northwest Chapter of ISA
Sponsor: Pacific Northwest Chapter of ISA
Description: It’s ALL about soil! Most people only have a vague idea of what soil is and how it works. You will learn more than you ever thought possible from this workshop about soil and how it works for trees. The reason you are alive, what nutrients are, how soil stores water and nutrients. The fundamentals that ALL humans on the planet Earth should know!

This dynamic workshop will explore the newly updated Best Management practices (BMP) for Soil Management in the Urban Environment, recently published by ISA, specifically to meet the requirements of trees. The workshop includes a thorough presentation on soil and tree health, a demonstration of BMPs in use, and a site visit to examine urban examples in downtown Bend, OR.

James Cassidy has been an instructor of Soil Science at Oregon State University for over 10 years. The introductory class now has over 200 students each term and is very popular. James is also the faculty advisor for the wildly popular OSU Organic growers club – OSU’s student farm. Coming from a non-traditional background (music industry for over 30 years) he is passionate about soil and is popular with students because of his dynamic speaking style. The student farm project has over 300 student volunteers on its list-serve and continues to grow. The farm cultivates over 50 different fruit and vegetable crops and is in its 15th season.
