While researching a topic, a student has taken the following notes:

• In a 2023 study, environmental scientist Jazmin Locke-Rodriguez and colleagues tested the use of floating treatment wetlands (FTWs) in Florida.
• FTWs are artificial floating platforms of plants used to remediate polluted or nutrient-imbalanced water.
• Finding: FTWs using marigold flowers removed 52% more total phosphorus than the control.
• Finding: The test yielded 65 market-quality blooms per square meter.
• The authors concluded marigolds showed “promising potential as a commercially viable remediating crop cultivated on FTWs in South Florida.”
