How does fertilizer runoff cause an algal bloom?
How does fertilizer runoff cause an algal bloom?
Fertilizer Pollution Facts But just as plants require nitrogen and phosphorus to grow, so do algae, and if they receive excess amounts of these chemicals, their populations explode, resulting in algal blooms. Algal blooms reduce the oxygen levels in water and cause illness and death in fish and other aquatic organisms.
How does fertilizer affect algae blooms?
Fertilizer is basically food for plants. 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.
Does runoff cause algal blooms?
Algal blooms can be dramatic and are a result of excess nutrients from fertilizer, wastewater and stormwater runoff, coinciding with lots of sunlight, warm temperatures and shallow, slow-flowing water.
What causes fertilizer runoff?
Excessive irrigation: Excessive irrigation or yard watering can also lead to fertilizer runoff. If agricultural land or garden soil becomes saturated with water, that water will run off to drier land that can absorb more moisture.

Why is an Aortogram performed?
An arteriogram or aortogram may be performed to detect any abnormalities in the blood vessels or the aorta. The most common issues are aneurysms, the narrowing of blood vessels, spasming of the blood vessels, arteriovenous malformation, thrombosis, or occlusion.
