Abstract
Bioretention systems capture and treat stormwater runoff by passing it through a vegetated filter bed including sand, soil, and organic matter (VSMM, 2017). Recently, bioretention systems with compost amended soil media are being explored for compost’s various benefits. Most compost, however, is rich in phosphorus and nitrogen, the key nutrients bioretention systems are designed to remove. In saturated systems, compost can transform an intended nutrient ‘sink’ into a ‘source’ leading to further contamination of downstream water bodies. This research aims to study the efficacy of engineered bioretention media in supporting vegetative establishment while leaching minimal nutrients.
