Some viral tips are promoting the idea of using cheap commercial fertilizers as ice melt. The reason is the active ingredient, ammonium sulfate, works as a de-icing agent, and the fertilizer can be spread easily over large surfaces. So what's the problem? When temperatures rise, all of that fertilizer will end up in the melted snow and ice, creating a toxic runoff that can affect your municipal water or local waterways. It's best to avoid this tip and stick to more natural de-icing solutions.
