What is stormwater runoff?

Stormwater runoff refers to the water flow that occurs when precipitation, such as rain or melted snow, falls onto surfaces and cannot be absorbed into the ground. This excess water typically flows over land surfaces, such as roads, rooftops, and paved areas, and can collect pollutants and debris along the way.

When precipitation occurs, some of the water may infiltrate the soil, but if the ground is saturated or impervious surfaces are present, the remaining water contributes to runoff. This runoff can lead to various environmental issues, including soil erosion, water pollution, and flooding, highlighting the importance of managing stormwater effectively. Thus, it is crucial to understand the characteristics and implications of stormwater runoff in the context of fertilizer application and environmental protection.
