Constraints to Tree Growth Imposed by Urban Soil Alkalinity (3.100281)
Date: February 1990Creator: Ware, George
Type: Article
Description:The selecting of trees for urban planting in the Chicago region requires attention to two serious limitations—soil alkalinity and clayiness. This region has extensive areas of soil derived from alkaline glacial till. Urbanization often brings about a mixing of surface and deeper material producing a tree-root environment scarcely conducive to proper growth. The following discussions deal mainly with situations in the Chicago area, but in-formation and ideas are thought to have applicability to urban areas elsewhere.
