Abstract
Calcium carbide is a chemical compound with the chemical formula of CaC2. Itsindustrial use involved in the production of acetylene and calcium cyanamide. Inessencecalcium carbide poses a greater threat to soil fertility, leading to low productivityof cropsand livestock. The study was conducted at different mechanic workshops in Egor local government areaof Edo state. The study was done to access effects of calcium carbide on soil fertility. Theexperiment was a 3×3×3 factorial experiment that is three different workshops at threedifferent depth replicated three times. The total amount of hydrocarbon in location1shows there is decrease in soil fertility furthermore the available phosphorus decreasesinlocation 1 inferred that phosphorus is being held up by aluminumand hydrogenions. Same with the results for available phosphorus in location 2. Recommendations suchasmulching, physical methods such as scraping is needed to improve soil fertility
