Why is it discouraged to fertilize grass within 20 feet of a shoreline?

The correct answer is focused on preventing nutrients from reaching the water, which is crucial for maintaining the ecological balance of aquatic environments. When fertilizers are applied near shorelines, rainwater and runoff can carry excess nutrients, such as nitrogen and phosphorus, into nearby bodies of water. This can lead to algal blooms, which deplete oxygen levels and harm aquatic life, disrupting the ecosystem.

By discouraging fertilization within 20 feet of a shoreline, we are taking proactive measures to protect water quality and prevent potentially harmful consequences for aquatic ecosystems. This practice aligns with responsible land and water management strategies that prioritize environmental health.
