Phytoremediation to remove nutrients and improve eutrophic stormwaters using water lettuce (Pistia stratiotes L.). Excessive N and P in surface waters can promote eutrophication (algae‐dominated, low‐O2 waters), which decreases water quality and aquatic life. This will help reducing the need to add more supplementary fertilizer. In this work, dried duckweed was incorporated into agricultural soil in microcosm, column, and field tests to evaluate biological N cycling, nutrient retention, and crop yield compared with compost, diammonium phosphate (DAP), and an amendment‐free control. Therefore, impacts of different biochar amendments (biochar type, application rates, etc.) However, it is hypothesized that elevated concentrations of pathogenic bacteria may be present in the biomass of duckweed grown in ABR effluent. Whilst work on various aspects of duckweed is advancing, there is paucity on its utilisation as soil fertility amendment, although Culley et al.
