Phosphorus Supply and Demand MIT

Phosphorus is mined primarily as phosphate rock, a fairly common rock found worldwide. It takes about 1 ton of phosphate to produce 130 tons of grain, although this figure is highly variable depending on soil conditions, farm history, crop type, and fertilizing efficiency (Vaccari, 2009). Approximately 191 Mt (megatons = millions of tons) of phosphate rock were mined last year, and the USGS
