Peak phosphorus

A new report from the Soil Association, A rock and a hard place: Peak phosphorus and the threat to our food security, highlights the urgent need for farming to become less reliant on phosphate rock-based fertiliser. Worldwide 158 million tonnes of phosphate rock is mined every year, but recent analysis suggests that we may hit 'peak' phosphate as early as 2033, after which supplies will become increasingly scarce and more expensive. The report suggests changes in the way we farm, eat, and manage human excreta.
