How much coal and glass?
Way back in 1963 when my father cut down our barn, and I do mean barn with haymow and door to put bales up in, in my area of town there were seven such barns turned into garages, they shoveled the dirt out to put in a cement floor and put the dirt into the garden.
One area of the barn was a coal bin; to this day I occasionally till up a chunk of coal.
Dad put manure in the garden every seven to ten years but the garden has always produced well, especially potatoes and roses.
I still turn up glass every now and then but have been working the garden barefoot for twenty years with no problems.
Kids marbles are another item I find more than rarely in both of my gardens and they are fifty miles apart.
