“…Most of the irregular experiences occasioned by crude oil contamination of the soil include drastic farmland degradation, poor soil aeration, massive reduction of soil fertility, raised temperature of the soil, soil structure obliteration, annihilation of the soil microbial communities, low productivity of the crops, yellowing of the leaves of the crop, stunted growth, wilting of the crop, rotting tubers of the crop, the occurrence of crop diseases and burnt crop leaves [17]. The collective effects of those conditions often led to poor crop yield or massive crop failure [25,26]. For instance, the significant impact of crude oil spills on cassava production was observed [27] to include rotting tubers, stunted growth, poor yield, and crop failure.…”
