What is the required buffer zone distance near waterbodies for fertilizer application?

The required buffer zone distance near water bodies for fertilizer application is established to protect water quality. A buffer zone helps prevent runoff and leaching of fertilizers into nearby aquatic systems, thereby reducing the risk of nutrient pollution, which can lead to problems such as algal blooms and degradation of aquatic habitats.

A 25-foot buffer zone provides a significant area where vegetation can absorb excess nutrients before they reach the water body. This distance helps maintain the integrity of the ecosystem by ensuring that fertilizers do not directly enter streams, rivers, or lakes during application or through subsequent rainfall events. The guidelines often reflect best management practices recommended by agricultural and environmental agencies, emphasizing the importance of this buffer in safeguarding water resources.
