COMPOST'S ROLE IN URBAN GARDEN SOIL REMEDIATION

摘要

A community research project, funded by the National Institutes of Health, is underway to determine the extent of risk from heavy metal contaminants in urban soils used for urban farming and gardening projects. Murray McBride, PhD, a principal investigator on the project and director of Cornell's Waste Management Institute in the Department of Crop & Soil Sciences, says compost could play a key role in remediating contaminated garden soils. What they're testing, both through research in their greenhouse studies and through field studies, is adding different levels of compost and seeing what the effect is on toxic metals in crops.
