The adoption of petroleum and its derivative such as diesel in all transport forms hasamplified its pollution dangers to the soil. This research is aimed at modelling the remediation of diesel contaminated soil by palm bunch ash. A plot of land measuring 4.8m 2 was divided into nine equal cells of 0.36m 2 with a furrow of 0.2m created between cells. The cells were randomly contaminated with diesel and treated with 0.0kg, 0.1kg and 0.2kg of palm bunch ash. After eight weeks, it was observed that the 0.2kg palm bunch ashreduced the soil total hydrocarbon content by 76%, while the 0.1kg and 0.0kg palm bunch ash gave reductions of 70% and 20%, respectively.Three models, namely zero, first and second order models, were developed and tested. The first order model gave the best description of the remediation of the diesel contaminated soilby palm bunch ash compared to the zero and second order models. Therefore, it was concluded that palm bunch ash can serve as a good remediating material for a diesel contaminated soil, and that a first order model can suitably predict the remediation.
