In addition to research, the GPRI also facilitates networking, dialogue and awareness raising among policy makers, industry, scientists and the community on the implications of global phosphorus scarcity and possible solutions.

Soil Phosphorus Forum: The Soil Phosphorus Forum is an online open space of scientific discussion about soil phosphorus and the mobility of soil phosphorus. Any person can suggest a new post and it is our vision that it becomes community owned and ran by you, for you. Feedback is welcome and continually needed to improve the forum and make sure it fits its purpose. You can send an email to Daniel Blackburn or to Courtney Giles or leave a comment here.
