What recent events affect the potash market?

It had to meet conditions within a year before the loan could be approved.
• 2025. World consumption of potash in fertilizer was estimated at 41.6 million tons of K2O against 40.6 million in 2024, and was projected to reach 45.3 million tons in 2029. World capacity of 66.1 million tons was projected to reach 77.4 million tons by 2029, mostly MOP from Laos and Russia.
• November 2025. Potash was added to the US Final 2025 List of Critical Minerals.
