We are excited to announce the upcoming Organic Phosphorus Workshop 2026, which will be held in Charlottetown, Canada, from July 13-16, 2026. The meeting will build on the four previous workshops held in Switzerland (2003), Panama (2013), UK (2016) and Chile (2023). This workshop offers a unique opportunity to exchange knowledge and ideas with the international scientific community involved in organic phosphorus research across diverse ecosystems.
