  • 11:15A | Mitigating Difficult Conditions for Tree Health Management

    Urban soil is often compacted during anthropogenic activities which presents a challenging substrate for tree growth. Over the past five years, several techniques for de-compacting soil (air-spading, vertical mulching, Vogt) have been evaluated alone and in combination with soil amendments such as biochar, organic fertilizers and/or a woodchip mulch. Effects on soil quality (bulk density, organic matter, vegetation cover, cotton strip degradation, root dry mass, and earthworm counts) of a heavily compacted soil as well as tree health were monitored over five years. The aim of this presentation is to provide on update as to which treatments provided the most cost-effective long-term soil de-compaction measures for arborists.
