so check this out. i was reading up on florida fertilizer, came across a uni page which said this.
essential nutrients required in very small quantities for turfgrass growth are referred to as 'micronutrients' i.e., iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), chlorine (Cl) and molybdenum (Mo).
looks like used oil to me. so what is it in used oil which kills grass? i have a patch of yard which i accidently spilled a gallon of used oil about 10 years ago.
to this very day nothing will grow there. i have dug up the bad soil and replaced it many times and still nothing grows.
