Potash is the most attractively priced major input right now. Pre-buying fall 2026 needs makes sense before Brazilian demand cycle tightens supply.

| Driver | Impact |
|---|---|

| Belarus sanctions impact | Belarusian potash remains under Western sanctions; Canadian and Russian supply has partially filled the gap. |

| Currency effects | CAD/USD movements affect competitiveness of Canadian potash imports. |
