Why Are We Regulating Fertilizer Use?

Many fertilizers contain nitrogen and phosphorus, also known as nutrients. Pollution from nutrients harms our natural waterbodies – springs, lakes and rivers – by causing algae blooms and poor water quality. How does nutrient pollution get there? When yards are over-fertilized, the excess nitrogen and phosphorus flow with rainwater into the same stormwater system designed to keep your property and roads from flooding during heavy rain. By doing something as simple as choosing fertilizer carefully and applying it properly, together we can make a big impact on the health of our natural water bodies.
