ECIL | According to AI:
"28% UAN (Urea-Ammonium Nitrate) liquid fertilizer can melt ice due to its urea content, which acts as a non-corrosive, chloride-free de-icer, effective down to approximately \(21^{\circ }\text{F}\) (\(-6^{\circ }\text{C}\)). While it works, it is less effective at lower temperatures compared to salt. It is often used to prevent ice on, or around, sensitive vegetation."
