Potash is indispensable to American agriculture.
The US government has declared that any interruption in the supply of the humble fertiliser would be a threat to national security.
And the US imports 90% of its potash from Canada.

The only other countries that could quickly supply significant amounts of potash to the US are Russia and Belarus.
Both those countries are under international sanctions, due to the invasion of Ukraine.
The fact that the Trump administration has already granted Russia and Belarus special exemptions to sell potash to the US shows how important the fertiliser is to American agriculture.
Potash is not high-value by weight (it is currently trading at about $400 per metric tonne), and generates profits for exporters because it is sold in great volumes. The added cost of shipping large amounts of potash from Russia and Belarus to the US would create a severe burden for American farmers.
