Soil reaction (pH), aluminum (Al), iron (Fe) and phosphorus (P) are the parameters which presences in soil are related to each other. The role of each parameter on the grow than development of plants is very significant. Liming and organic mater amendment are some efforts that are frequently perform...

The composition of the soil fauna community have played an important role in regulating decomposition and nutrient cycling in agro-ecosystems (include cocoa plantation). Changes in food availability and conditions in the soil habitat can affected the abundance and diversity of soil fauna. This study...
