There is currently a vigorous debate regarding the lifetime of remaining high quality phosphate rock reserves, with estimates varying from a few decades to a few hundred ...

Improved phosphorus use efficiency in agriculture: a key ...

This type of P use is not sustainable because fossil phosphate rock reserves are finite. Once the high quality phosphate rock reserves become depleted, too little P will be available for the soils of food-producing regions that still require P supplements to facilitate efficient utilization of resources other than P, including other nutrients.
