Abstract: In compacted, erosion-prone post-construction soils, amendments are often needed to improve stormwater infiltration and support vegetation establishment. Previous research has demonstrated the benefits of compost for enhancing soil physical properties and promoting vegetation growth. However, the effectiveness of compost may vary depending on whether it is applied as a surface blanket or incorporated into the soil.
This study aims to compare the effectiveness of compost blankets and incorporated compost on vegetation establishment and soil physical properties. Additionally, it will evaluate the influence of compost application methods on runoff quantity and quality. The experimental design includes treatments with compost surface blankets, incorporated compost at two rates (30% and 12% by volume), and a no-compost control. Plots will be delineated on a 5% slope to direct runoff into collection tanks, seeding will be done with recommended mixes by NCDOT, and compost incorporation plots will be covered with excelsior matting.
Preliminary results indicate significant differences in total biomass and water content among treatments, with higher compost rates generally improving both parameters. Bulk density and infiltration rates also vary significantly across different regions and compost treatments, highlighting the potential of compost incorporation to enhance long-term soil structure and stormwater management.
This research will provide valuable insights into the use of compost for improving soil physical properties and managing stormwater in post-construction landscapes. The findings will guide the implementation of compost-based soil amendments to support sustainable vegetation establishment and stormwater control in rapidly developing areas like North Carolina.
