Supply is concentrated, making it vulnerable to shocks.
Export restrictions on fertilizer would tighten global nutrient supply and lift urea, ammonia and potash prices, raising feed grain production costs for buyers. Calls for open trade point to supply easing, but restriction risk remains a bullish cost factor.
