Phosphorus and nitrogen contribute to water pollution and cause harmful algal blooms. New research shows how mats of floating flower beds can take advantage of these nutrients while cleaning the water.

Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.

New research shows that one-third of yearly nitrogen runoff from Midwest farms to the Gulf of Mexico occurs during a few heavy rainstorms. New fertilizing schedules could reduce nitrogen pollution.
