African farmers need to increase productivity to fight poverty. Using better farming methods like fertilizer can help. A study in Kenya looked at why some farmers use fertilizer more than others. They found that factors like age, education, access to credit, and type of crops grown affect how likely a farmer is to use fertilizer. Also, farmers in drier areas use less fertilizer because it's riskier and less profitable. To help farmers use more fertilizer, it's important to improve access to credit, promote fertilizer in drier areas, and invest in rural infrastructure.
