Abstract: Charcoal burning is one of the common practices in most of the rural areas of Nigeria. This study considers feedback effect of charcoal burning on physical and chemical soil properties with a view to examining status of soil nutrient in Saki, Oyo State, Nigeria. Ten composite soil samples were collected from each demarcated quadrats (5 m × 5 m) of charcoal production site (CPS) and adjacent field site (AFS) at 0 cm-15 cm (topsoil) and 15 cm-30 cm (subsoil) and subjected to laboratory analysis. Mean, standard deviation and coefficient of variation (CV) examined the variation within the set of variables. The study revealed that soils exhibit homogeneity in all the examined parameters of the charcoal production site except silt and phosphorous. This is to show that surface burning is a factor for nutrient distribution and availability in soil. It was generally observed that clay is resistant to heat having being insulated from surface heating.

Keywords: charcoal production; soil fertility; savanna zone; soil; fire; Nigeria.
