Video: Brief introduction to P removal structures
The P-TRAP software allows a user to design different types of phosphorus removal structures based on site conditions, phosphorus absorbing material characteristics and structure parameters. The P-TRAP software allows users to explore different designs to meet performance goals for P removal amounts and material lifetime. A database of P absorbing material characteristics is included based on previous laboratory experiments.
Training Videos
The training videos/course for P removal structures is now available for free on the ASA (American Society of Agronomy) website (agronomy.org). People who are not part of the ASA system will need to create a new user account, but the courses are free for use. For information on how to access the course see this PDF document.
Here’s a direct link to the course (which will prompt for user sign-in or creation of a new user account):
