    Up By Roots: Soil workshop


    Based on his 2008 ISA published book, Up By Roots, James Urban brings the ISA’s successful regional soil workshop to the annual meeting. The workshop will be divided into four sessions: A basic soils review, a review of urban soils, and outdoor field sessions where hands on stations allow participants to touch and experience soil, the tools of the soil trade, and how to undertake an urban soils evaluation.  In the final session, participants will return to a group setting to review how to resolve basic soil problems and discuss actual field situations they have encountered in their work.  Participants will be encouraged to join in the development of alternative solutions and evaluate the practicality, limitations and cost effectiveness of proposals.  It is hoped that a cross section of arborist from different geographic regions will participate to broaden the types of soil problems being discussed.
