Optimizing Artificial Soil Mixes for Urban Green Spaces: Plant Growth and Carbon Sequestration Balance

Urban Farm DB summary

This study developed and assessed four artificial soil mixes (ASMs) using eight common materials to optimize plant growth and carbon reduction in urban green spaces. ASM_A showed comparable or superior plant growth to control soil, attributed to high organic matter and cation exchange capacity. ASM_D had the highest carbon content (27.60 wt%) for long-term sequestration but was limited in early plant growth due to lower nitrogen and phosphate.
