I'm looking for an anti microbial wood preservative that won't leach out in rain and soil.

This paper say salt from salt water leaches out with exposure to fresh water, but sulfate in the water stays in the wood and crystalizes. I can't find any more information regarding the effectiveness of highly concentrated sulfur against microbes.
Inb4 >copper sulfate
Leaches out of wood
>Silver
I don't have any money
Sodium lauryl sulfate sort of seems like a decent candidate but I can't find any info on whether the sulfur will crystalize in the wood. Anyway the idea originally was to find a salt lake with a high sulfur content, soak lumber into it and wa la anti fungal lumber.

It depends on what you're using the wood for. Traditionally farmers would mix rust and rapeseed oil to make a paint that preserves wood. That's why barns are typically rust red. Vikings and other seafaring people would coat wood with pitch or tar to preserve it from water damage. Technically pressure treating wood with arsenic is a "natural" way to preserve wood, but it's not ideal for tables or garden beds.

Everything leaches out. It's just a matter of how quickly.

You know that's just soap, right?

Pic related was built about 800 years ago.

lacquer. made from poison ivy and pine resin. if you want to be cheap use paraffin wax in a pressure cooker to impregnat the wood.
