Cow pasture is the reason for the high levels of phosphorus in the water resulting in algal blooms.
- Algae blooms, also known as overgrowths of algae, occur quickly when phosphate and nitrogen levels are too high.
- Algal overgrowth burns oxygen while obstructing sunlight from reaching submerged plants.
- Although cow pasture (manure from cow dung) is frequently kept in enormous storage "lagoons," some of it unavoidably leaks into the groundwater and neighboring rivers, causing blue-green algae, or cyanobacteria, blooms.
- Commonly, runoff or soil erosion from fertilizer and manure introduces these nutrients.
- Toxic algal blooms may occur when these extra nutrients combine with hot sunny days. The blooms are harmful to people, animals, and fish.
