Can Fertilizer Be Detrimental?

Overapplication of fertilizer can be detrimental to plants, leading to their demise. Additionally, surplus fertilizer can wash away into nearby streams and lakes, which may result in toxic algal blooms harmful to aquatic ecosystems, as well as to humans and pets. Furthermore, runoff from both lawns and farming activities can also lead to the formation of "dead zones" in coastal waters, where aquatic life struggles to survive.
