ABSTRACT
Calcium carbide is a chemical compound with the chemical formula of CaC2. Its industrial use involved in the production of acetylene and calcium cyanamide. In essence calcium carbide poses a greater threat to soil fertility, leading to low productivity of crops and livestock.
The study was conducted at different mechanic workshops in Egor local government area of Edo state. The study was done to access effects of calcium carbide on soil fertility. The experiment was a 3×3×3 factorial experiment that is three different workshops at three different depth replicated three times. The total amount of hydrocarbon in location 1 shows there is decrease in soil fertility furthermore the available phosphorus decreases in location 1 inferred that phosphorus is being held up by aluminum and hydrogen ions. Same with the results for available phosphorus in location 2. Recommendations such as mulching, physical methods such as scraping is needed to improve soil fertility.
