Abstract: In Mubi area, farming activities by the peasant farmers are becoming less productive compared with the past, due to degradation of the inherent fertility status of the soils. This might be attributed to so many human induced, agronomic and climatic factors coupled with less effective or poor soil conservation techniques by the farmers. Therefore, this study aims at highlighting soil fertility degradation in Mubi area, North-eastern part of Nigeria. It was revealed from this study that soil erosion, overgrazing, deforestation, crop removal, indiscriminate bush burning were the common substantive factors responsible for soil degradation in the area.
