Excess nitrogen from the fertilizers can cause eutrophication in the ocean, which can lead to harmful algae blooms
What are the effects of fertilizer runoff?
Too much fertilizer can actually kill the plant and excess fertilizer can runoff into streams and lakes causing toxic algal blooms that are harmful to aquatic life and even people and their pets. Excess fertilizer runoff from lawns and agricultural applications also contribute to aquatic “dead zones” in coastal areas.

If you feel like this won’t be enough, go back over and apply the fertilizer sparsely in perpendicular stripes.
How do you stop manure runoff?
Manage runoff and leaching from stockpiled manure. Stacking solid manure on a concrete pad will reduce leaching of nutrients through the soil. Also, placing the stockpile in an open-sided shed, on a level surface, and above the seasonal high-water table will reduce runoff risk.
Who is responsible for water runoff?
Fifty years later, California still follows the modified “civil law” approach known as the “rule of reasonable use.” This rule makes a landowner responsible for discharged surface water so as to minimize the harm and burdens to surrounding neighbors.
How bad is stormwater runoff?
Stormwater runoff can cause a number of environmental problems: Fast-moving stormwater runoff can erode stream banks , damaging hundreds of miles of aquatic habitat. Stormwater runoff can push excess nutrients from fertilizers, pet waste and other sources into rivers and streams.
What are some negative effects of runoff?
- Flooding – Damage to public and private property.
- Eroded Streambanks – Sediment clogs waterways, fills lakes, reservoirs, kills fish and aquatic animals.
- Widened Stream Channels – Loss of valuable property.
What is street runoff?
Urban runoff is either wet weather (rainwater) or dry weather (water waste) flows from urban landscapes into storm drain systems that lead to the beach. ... It is now urban runoff, or the waters that flow from our streets and alleyways to the ocean, that has become the single largest source of water pollution today.
