USE.240-Impacts of Compost on Urban Soil Profile Health and its Cl…-AC26.CREF

This session examined the impacts of compost application in urban parks in California under state organic waste diversion requirements. After two years of compost use and comparisons with parks that had 30 years of applications, researchers found increases in soil carbon, nitrogen, and microbial biomass—especially at long-term sites, where carbon gains extended up to one meter deep. Short-term trials showed compost increased carbon dioxide emissions, reduced nitrous oxide and other nitrogen gases, and did not affect methane emissions. Compost was particularly effective at lowering nitrogen-related emissions in areas irrigated with recycled water, without reducing plant health or available soil nitrogen. Overall, the findings highlight compost’s potential to improve soil health, reduce greenhouse gas emissions, and support climate and public health benefits in urban environments.
