Everyone talks about climate change in coffee. Almost nobody talks about phosphorus—and that's the problem.
Our new issue examines why this element (essential for root development, flowering, and energy transfer) is becoming a geopolitical chokepoint. Morocco controls 70%+ of global phosphate reserves. Prices are volatile. And Ethiopian coffee farms are working with acid soils that lock phosphorus away from plant roots.
This isn't about running out. It's about control—who controls the inputs controls the terms of production.
For roasters, buyers, and agronomists: phosphorus literacy is now part of origin strategy.
