Researchers ground waste oyster shells into acidic Gambian farmland; the calcium-rich powder helped neutralise the soil and may improve groundnut yields

In West Africa, oyster shells are becoming an essential tool for enhancing farmland productivity. When crushed, these shells function similarly to agricultural lime, enriching acidic soils to support better crop yields. This method is particularly impactful in The Gambia, where groundnut farming is thriving. Ongoing research aims to identify the most effective usage rates of shells, promoting a blend of waste management and sustainable agricultural practices.
