Ukraine
It sounds like he had a 50 pound bag of fertilizer.
I remember the time I took a load of junk to the city dump. The free city dump, they used to be free.
Anyway while I was unloading I found about a thousand pounds of nitro explosive in hundred pound paper bags. I loaded up all their was in unbroken bags. I got six or seven hundred pounds which was not spilling all over the ground.
It was fertilizer first, explosives second as far as I was concerned. And we used it in the fields. Used it as fertilizer because it was fertilizer.
I was good at finding useful things at the dump when I was a kid, still am.. Almost world famous for doing that.
