Understanding of different levels of soil calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), cation exchange capacity (CEC), and percentage base saturation (BS), is important in the management of forest ecosystems. However, there is limited documentation on the status of these elements in the undisturbed forest sites (CFS) crop-agriculture (ADS) and livestock grazing (DGS) disturbances in the tropical coastal forests. This chapter attempts to address this deficit by presenting soil fertility based on exchangeable bases’ status and variations across undisturbed forest sites (used as a control), crop-agriculture and livestock disturbed sites in the coastal zone of Tanzania. The chapter aims to add knowledge on the management of tropical coastal forests. Indeed, this chapter shows that crop-agriculture and livestock grazing disturb soil chemical properties in tropical coastal forests. Therefore, it is essential to protect undisturbed forest while putting more efforts to restore the disturbed sites for sustainable forest management along the coastal areas.
