Following the Belt and Road policy, our research and development team went into the fields of Ghana. In order to expand the African market and provide Ghana with more locally appropriate seaweed fertilizer, during the investigation, we had a practical discussion with relevant departments in Ghana, based on the current situation of fertilizer application by local farmers, we learned about the local fertilizer sales and use habits, as well as the type and price status of fertilizer products. At the same time, we also visited the local agricultural products business units, and according to the local tobacco and cocoa cultivation, we introduced our fertilizer application method to them. This has yielded considerable results in Ghana's tobacco and cocoa cultivation, which has better served local farmers.
