Urban Soils

As urbanization spreads across the globe, so do urban soils in the form of lawns, vacant lots, and median strips.  It is important to understand the function and structure of these soils in order to better manage and understand our mosaic soil environment.  Soil processes are important for many ecosystem functions in urban areas, yet soil research in urban ecosystems remains challenging.

 

The transformation of landscapes from primarily agricultural and forest uses to urbanized landscapes has the potential to greatly modify soil properties and processes. Although the effects of conversion of native ecosystems to agricultural use have been relatively well-studied, conversions to urban land uses have received little attention. As land is converted to urban uses there are direct and indirect factors that can affect soils. Direct effects include physical disturbances, burial or coverage of soil by fill material and impervious surfaces, and soil management inputs (e.g., fertilization and irrigation). Indirect effects include changes in the abiotic and biotic environment as areas are urbanized. The direct effects often lead to a new soil "parent material" on which soil development then proceeds. Indirect effects that can influence this development, as well as processes in intact soils, include the urban heat island effect, introductions of exotic plant and animal species, and atmospheric deposition of various pollutants. Moreover, toxic, sub-lethal, or stress effects of the urban environment on soil decomposers and primary producers can significantly affect soils.

 

Urban soils research at the Baltimore Field Station includes characterization of decomposition rates, nutrient cycling, carbon storage, presence of heavy metals, and classification of urban soil types.
