Findings: Using field data from previous studies, this paper modeled patterns in C and greenhouse gas dynamics following compost applications on three soil types and over long time periods (100 y). Results indicated that C storage would persist for 30 to 100 years, and that compost application resulted in a long-term increase in C capture and associated nutrient cycling. Few differences were seen when applying small amounts for multiple years versus a single one-time application. Compost with lower C:N ratios led to greater sequestration but higher N2O emissions.
