The United Nations is scrambling to find a solution to the disruption in fertilizer shipping caused by the closure of the Strait of Hormuz. Roughly one-third of the world’s seaborne fertilizer, particularly nitrogen-based urea, is shipped through the strait. India, Pakistan, Brazil, Ethiopia and other countries in Asia and Africa heavily rely on fertilizer shipped through the crucial waterway and are now facing low crop yields and shortages due to their inability to obtain it.

Farmers in Latin America are already skipping their second corn planting as fears of global crop shortages loom.

As the key chokepoint remains blocked, the U.N. says it’s working on a plan to restore shipping.

“Extensive meetings” have been held in New York over the past two weeks to figure out how the plan will work, said Juliette Touma, director of communications for the United Nations Office for Project Services. Touma did not explain what the initiative will be, but time is running out for countries that depend on fertilizer shipped through Hormuz to plant and grow their crops.
