EmpiricalRequires evidence
No peak phosphorus; the problem is runoff.
The claim
Phosphorus will not run short for centuries: phosphate rock reserves cover 300 to 400 years of fertilizer demand and resources over 1,000, so the binding phosphorus problem is runoff into water, not supply.
Argument role: boundary. Two sources in two chunks agree in direction (IFDC 300-400 years; USGS >300 bn t, >1,000 years). Potassium reserves ~90 years at current rates (chunk 430) is the tighter mineral, worth a check. The nutrient problem for abundance is losses to water (eutrophication), the same failure as C-K8HK4GWRSV.

According to the International Fertilizer Development Center, the world's phosphate rock reserves and resources are adequate to meet fertiliser demand for the next 300 to 400 years.
groundsSource document
The real concern about plant nutrients is the environmental, and hence economic, consequences of their unwanted presence in the environment, mostly in water.
