More than 300 guests from the cocoa industry, governments, NGOs, academia, and research institutes from 28 countries in Africa, the Americas, Asia, and Europe, were at this meeting to address some of the most pressing issues in cocoa sustainability. The fertilizer study was done in Ghana and Cote d’Ivoire. In these countries, entire regions, such as the famous cocoa belt of Soubre, are known to suffer from tree mortality and decline in yields. Fertilizer can be one of the solutions for the problems cocoa farmers and companies face. Until now little was known about fertilizer use for cocoa. Eg. How and to what extent does fertilizer affect cocoa farms? How much does it cost, and which returns on investment can be expected? This study shows that already after one year of application the foliage on degraded farms is widely rebuilt. “You can no longer see the sky” farmers say. We see a clear impact on production,despite significant variability in productivity explained by rainfall and the degree of maintenance. A rough calculation also shows that the estimated potential market for fertilizer is over 1 million tons. This represents a yearly revenue of at least US $ 500 million to the fertilizer industry and credit institutions.
