Urban Soils

Soils in urban and suburban areas affected by development are frequently compacted, cut, and filled, resulting in a poor environment for plant growth and increased risk of runoff and harm to the aquatic environment. Our research to date has focused on compost amendment of landscape soils to improve soil quality and plant growth. It includes a comparison of surface-applied and incorporated compost in a woody landscape established on converted agricultural land (begun in 2001), and a project comparing surface-applied and incorporated compost and biosolids products applied to cut and compacted subsoils within a highway landscaping zone (begun in 2007). Future work will include rain garden and bioretention research as part of a low-impact development project planned for WSU Puyallup.
