City-soil compaction is a major problem for landscape architects. New research shows exactly how to amend physical, chemical, and biological soil properties to achieve high infiltration rates so that entire landscapes becomes a stormwater system that prevents runoff by absorbing water from impervious areas.

Learning Objectives:

  • Learn how to amend compacted acidic subsoils to greatly increase the infiltration rates, reduce the runoff rates, improve water quality, and improve the deep rooting of plants.
  • Learn how different compost amendments affects the infiltration, density, porosity of subsoils, and tree rooting in the Midwest on compacted glacial soils.
  • Learn how to amend compacted alkaline subsoils to greatly increase infiltration rates, reduce runoff rates, improve water quality, and landscape plantings.
  • Learn by contrasting the three methods by the panel discussion and through questions by the audience.
