Soil macro-fauna play an important role in soil fertility improvement in different agricultural systems. However, limited research has been done to assess the role played by soil macro-fauna to soil fertility enhancement in cocoa-based agroforestry s

Soil macro-fauna diversity and abundance greatly influence soil fertility. However, little has been done to confirm this hypothesis in cocoa-based agroforestry systems. It was in this light that this research work was undertaken in order to fill the

Soil fertility decline has pushed farmers across the world to resort to chemical fertilizers in order to improve soil fertility and enhance crop yields. In agroforestry systems, the application of chemical fertilizers is a call for concern considerin
