Urban agriculture is an essential part of long term urban sustainability. It can help mitigate many problems that we have in cities, such as food security, racial justice, global warming, waste disposal, etc. However, urban soils are often contaminated and the unavailability of clean soils limits the success of urban agriculture. The Clean Soil Bank Program mixes pristine sediments with compost and generate constructed soils that can potentially be used as a growth medium. Efforts are being made to understand the physical and biogeochemical properties of such constructed soil mixes, how it evolves in the short and long term, and how well they can support plant growth. BUEE students will join a team of researchers and practitioners in both field and laboratory work.
