Hey all, I have a question. About 30 years ago a sawmill near where I live closed and now the sawdust it left is rotten/ decomposed. The question, can I use that in my garden as fertilizer? Its is already rotten, so I think its ok, but I wanted to ask first, better safe then sorry thanks in advance

Vase,

I would think that you have a good resource in that sawdust.  I can think of a couple of ways to useful it.

First, maybe consider using it as a top dressing.  This would leave the soil beneath undisturbed.  Alternatively you could mix it with existing soil.

If you are concerned about the sawdust being nutrient deficient, maybe consider adding some dilute urine and I am certain that you will have a very good growing medium.  Lastly, if you feel really ambitious, you could try to grow mushrooms in the sawdust.  If the mushrooms do grow then I think you will have absolutely magnificent bedding material.  I would suggest Wine Cap mushrooms for this option.

I grow exclusively in wood chips broken down by Wine Cap mushrooms and that bedding is fantastic.  I would think that if my chips work well then your rotted sawdust would be even better.

Eric

If they were processing raw logs only, I would go ahead and use the sawdust. If they were making fence posts, though, keep a close eye for anything that looks like a treatment operation.
