Moving phosphorus from noxious to precious (report on peak phosphorus)

The problem of excessive phosphorus loading is affecting water bodies in all parts of the world, including Lake Winnipeg, which is the tenth largest lake in the world by surface area, and among the most heavily loaded with phosphorus of the world’s great lakes. … While our total global phosphorus reserves remain unknown, statistics on deposits found in recent decades indicate that more phosphate is being extracted than discovered. Although dwindling rock phosphate reserves may challenge our industrial model of agriculture, it will also stimulate innovation and create new economic opportunities for capturing and recycling phosphorus back onto agricultural lands.
