Oil is not used in the production of fertilizers. Here's a quote I found in [1] "The macronutrients required by plants are N (Nitrogen), K (Potassium) and P (Phosphorus). Oil is hydrocarbon, made from H (Hydrogen) and C (Carbon). There are no plant nutrients in oil. Nitrogen fertilizer (N) is made from ammonia, which in turn is manufactured from natural gas, not oil" [1] http://peakoildebunked.blogspot.com/2005/08/28-isnt-fertilizer-made-from-crude-oil.html http://peakoildebunked.blogspot.com/2005/08/28-isnt-fertiliz...
