Soil quality refers to the ability of soil to perform its functions. Soil is especially important in regulating runoff of storm water and in supporting trees, shrubs, lawns and gardens. Urban activities, such as construction grading, often result in erosion, sedimentation and soil compaction. Soil quality refers to the ability of soil to perform its functions.
