I later learned that when you bury coins with no chemicals, the moisture in the soil will allow bacteria to come to the metal. Some bacteria will secrete cyanide in small amounts that will dissolve silver and gold and copper. The ions from the dissolved metals will slowly come to the surface in a vertical path, and will make electrical noise when they come to 10-25cm below the surface. This electrical noise is detectable with very sensitive instruments. But it does not happen if the ground is poisoned to kill the bacteria. You must wait maybe 20-50 years before the bacteria make detectable electronic noise. I think the chemicals that you put in the ground will kill the bacteria that make the signals that you can detect. Maybe the chemical poisons you put in the ground are gone before that time. Vinegar is not so bad like the stronger chemicals that I used.
