A field experiment was conducted in 2006 and 2007 cropping seasons to analyse the physical conditions of an Ultisol contaminated with spent lubricant oil alone, contaminated with spent lubricant oil and amended with organic wastes and organic waste amended soil only. The residual effect of these treatments was evaluated in 2008 cropping season. The treatments include; Spent lubricant oil (OS), OS+ burnt rice mill waste (OSBW), OS+ unburnt rice mill waste (OSUB), OS+ saw dust (OSSD), burnt rice mill waste (BW), unburnt rice mill waste (UBW) and saw dust (SD). A control (without oil or wastes) was also included. Results from the study showed that OS recorded significantly respectively. Organic wastes were observed to improve soil physical conditions with highest improvement observed in BW amendment.
