Nutrients and Eutrophication | U.S. Geological Survey
An overabundance of nutrients—primarily nitrogen and phosphorus—in water starts a process called eutrophication. Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can smell bad, block sunlight, and even release toxins in some cases. When the algae die, they are decomposed by bacteria—this …
Fertilizer Industry Handbook 2022
Nitrogen (N) Nitrogen originates from the air (78% of the earth's atmosphere is nitrogen). The most common process in nitrogen fertilizer manufacturing is to create ammonia from a mixture of nitrogen from the air and hydrogen from natural gas. Phosphate (P) Phosphate is sourced from insoluble calcium phosphate rocks.
