Kumapayi-Ibadan, Ibadan, Nigeria. The abandoned dumpsite of a car battery producing company became a barren degraded land where no plant could grow because of Lead contamination. Using varying levels of compost treatment, the land was turned fertile enough to grow mature maize crops. The CONTROL plot was untreated for reference while the plots at the back showing plant growth were treated.
