This study employed the use of the probit multiple regression model in analyzing the effects of farming practices employed by arable crop farmers on soil degradation. The objective was to identify any gap(s) that may exist in the current farming practices and the interventions required towards the evolution of more sustainable practices. A multistage sampling procedure was used in selecting 342 arable crop farmers from the study area. The study show that most of the arable crop farmers cleared and burnt their farmland before cropping, with majority (73.10%) allowing their farmlands to be left fallow for less than three years before farming on it again. Most of the farmers practice minimum tillage. Result of the probit multiple regression model shows that the practice of bush burning and clearing by the farmers will continue to encourage degradation. The effects of these farming practices on soil degradation culminated in continued crop low productivity. Education of arable crop farmers on alternative farming methods that could allow for the use of natural resources more sustainable is advocated for.
