The Sustainable Phosphorus Alliance hosts technical webinars on important phosphorus management issues. Our members participate in the webinars and the phosphorus sustainability community is invited to attend.
In addition, we create video abstracts of phosphorus sustainability research that has been published recently in respected, peer-reviewed journals through our series Phosphorus Science Now! The video abstracts are 5- to 10-minutes long and the researchers present their own findings.
Phosphorus: Past and Future
February 23 at 10:30 am CT
Drs. Jim Elser and Phil Haygarth–two big names in the field of phosphorus sustainability–have joined forces to write a book for lay audiences that describes the nature and history of phosphorus, its uses, and its twin role as both an essential ingredient of agriculture and a major contaminant of our waters. “Phosphorus: Past and Future”, available from Oxford University Press, discusses emerging efforts and innovations to develop phosphorus sustainability solutions to protect our food supply and water quality. We’ll have a high-level tour of the book with the authors and hear about the insights they gained from writing it. We’ll have plenty of time for the audience to ask questions of the authors.

Managing Your P on the Farm
What measures can be taken to ensure that crops receive all the essential phosphorus that they need without polluting the environment? Our panelists provided up-to-date information on sustainable phosphorus use and management during this 90 minute webinar. We heard from Krista Maruca of OCP North America about farmer engagement programs and the business case for nutrient stewardship and conservation; from Dr. Chad Penn of USDA-ARS about field conservation practices to reduce P losses from tile drainage and runoff; from Dr. Heidi Peterson of the Sand Country Foundation about the role nutrient management planning plays in appropriate fertilization; and from Dr. Josh McGrath of University of Kentucky about the role precision agriculture plays in P management.
