Throughout the United States, toxic algal blooms are wreaking havoc on bodies of water, causing pollution and having harmful effects on people, fish and marine mammals.
One of the main contributors to these algal blooms is excess phosphorus that runs off from agricultural fields and while there has been a lot of efforts in recent years by farmers to improve agricultural management, the problem persists and there is still a lot of work to be done.
