A study was conducted at Ongot in the humid forest zone (HFZ) of Cameroon to determine the extent to which selected soil quality indicators are affected by cassava cultivation along a chronosequence of 5, 10 and 20 years. Soil samples were collected from cassava farms along this chronosequence and from a nearby forest as reference. The samples were analyzed for soil organic matter (SOM), organic carbon (OC), total nitrogen (TN) and pH. SOM, OC and TN decreased significantly (P<0.05) following years of cassava cultivation. Thus after 20 years of cultivation, SOM and OC contents reduced by 50% compared to the reference (SOM=35.08 g kg-1, OC=20.39 g kg-1). TN decreased from 2.19 g kg-1 in the reference to 1.24 g kg-1 in farms where cassava has...
