Restoring hydrologic function in urban landscapes with suburban subsoiling

摘要: Dramatic persistent hydrologic changes accompany urban land development, most commonly attributed to increased impervious area and drainage infrastructure. Modern development mass grading practices also result in the routine of landscapes with highly disturbed compacted soil profiles. The common predictable is an pervious landscape greatly diminished infiltration capacity greenspace that might best be described as grass growing a thin veneer topsoil on fill. This paper describes use decompaction amendment restore function following removal asphalt playground at public school Baltimore, MD, USA. combination deep ripping compost referred suburban subsoiling, alluding adaptation agricultural subsoiling soils. In this field-scale comparison standard landscaping practices, supported highest rates, densest turf cover, organic matter root zone moisture, lowest bulk density. As sustainable alternative traditional topsoiling offers proverbial win-win solution, providing superior restored services lower life-cycle costs. Though significantly different than current can readily integrated modern only minor incremental practices. Suburban transform built environment through restores landscapes.
