Doug's Urban Sabbatical Fellowship Work

Project Page: Urban Underground: Agroecological Functions of Soils in the City

Urban agriculture, which utilizes local soils and nutrient rich organic amendments, is recognized for the ability to provide products, income, social benefits, and ecological services. Best management practices for anthropogenic soils (anthrosoils) and metrics to describe and evaluate their health are evolving. This project will evaluate soil development and soil health in urban soils that are used for food production. Best management practices for urban agroecological soil management will also be suggested.
