What to know about Fertilizer made from local rocks could help feed hungry in Africa

Researchers from Morocco, utilizing the Canadian Light Source facility, have developed a method to convert local potassium-rich syenite rocks into a soluble fertilizer. The process involves crushing, chemical treatment, and heating to create a sustainable alternative to imported potash for African farmers.

What happened

Fertilizer made from local rocks could help feed hungry in Africa Gaby Clark Scientific Editor Alexander Pol Deputy Editor Food insecurity is a major problem in many parts of the world, particularly Africa, where more than 300 million people regularly go…

Why it matters

Now, using the Canadian Light Source (CLS) at the University of Saskatchewan, researchers from Morocco have developed a way to produce fertilizer from local African rocks, which could make it easier for farmers to grow the crops needed to feed local residents.

Common ground

African soils, especially in central Africa, are rich in organic matter and have lots of water, but farmers still need fertilizers to provide important macronutrients like potassium, which strengthens plants' ability to absorb water, improves disease…
