The two fertilizer minerals that underpin global food security — phosphate for phosphorus, potash for potassium.
Phosphate: Phosphate is the basis of the global fertilizer industry that feeds 8 billion people. Morocco controls approximately 70% of the world's phosphate reserves, creating a critical food security dependency.
Potash: Potash is essential for global food security. Russia and Belarus together control approximately 40% of global potash exports — sanctions have directly disrupted global fertilizer supply and raised food prices.
Phosphate: Phosphate rock is the primary source of phosphorus for fertilizers that feed the world. Without phosphate fertilizers, modern agricultural yields would be impossible to sustain for the global population. Potash: Potash is a group of potassium-containing minerals essential for fertilizer production. Potassium is one of three primary plant nutrients and is vital for crop yield, quality, and drought resistance.
As tracked by Critical Minerals HQ, Phosphate is currently $440 USD/t and Potash is $316 USD/t. The two minerals are quoted in different units (USD/t vs USD/t), so see the live price panels above for the most recent figures.
Neither is "better" in absolute terms — each is engineered for different end-uses. Phosphate is primarily used for: Phosphate fertilizers for crop production, Animal feed supplements, Industrial chemicals and detergents, Food additives and preservatives. Potash is primarily used for: Potassium fertilizers for agriculture, Livestock feed supplements, Industrial chemicals (potassium hydroxide, carbonate), Food preservatives and processing. The right mineral depends on the application.
Phosphate and Potash are quoted in different units (USD/t vs USD/t), so a direct numeric rarity comparison from spot price alone is indicative only. See the indexed 25-year chart on the live page for relative scarcity behavior.
Specific US import-reliance percentages are not in our on-file reference text for either Phosphate or Potash. See the official USGS Mineral Commodity Summaries for the latest figures.
Phosphate top producers (USGS): China, Morocco, United States, Russia. Potash top producers: Canada, Russia, Belarus, China. The mineral whose first-listed producer accounts for a larger share of global output carries the greater supply-chain concentration risk.
