I wouldn't use it. Its probably full of rocks and clay that won't spread out nicely. Even stuff you buy that is supposedly "screened" still has too much for my liking. Last year I used 70% screened sand and 30% screened topsoil. This year I will probably just use 100% sand. The grass seems to grow great even in sand because the roots go pretty deep. Maybe post a pic of the excavated dirt and some on here will opine on whether it looks good enough to use.

 

Thanks. I've attached some pics for add'l feedback.

 

If you really wanted to use that dirt you could build a soil sifter with hardware cloth.

I used some with 1/4" mesh and it worked well for some top soil that was a little clumpy.

 

I did and regret it but I had nowhere else to put the last remaining but I had left. The grass seed I out down there didn't fill in like it did everywhere else. I'll probably just cover it with sand.

 

Is this subsoil that you're considering light leveling with? Or are you leveling a yard by raising it a good few inches/feet. If light leveling then no, it'll be more trouble than it's worth. But it may be ideal subsoil for raising up areas that need a good compactable base.

Edit: looking closer at your pics, seeing the slab, and I'm assuming this is the excavation soil from where the slab was dug down. That's approx 6" of dirt, which in most cases would be categorized as topsoil. If so fee free to level w it, being mindful to collect as much of the gravel as possible.

 

The dirt in the pics come from recent deck as fence build and I'm currently building new patio (last pic)so I was concerned about using it since it was dirt that had been dug up.

I hv a lot of little divets and hv 14,000sqft backyard so just thinking about all this is overwhelming.

...a soil sifter with h/w cloth...sounds interesting

 

You shouldn't use subsoil from deep holes on the top layer of the soil. While it can be OK in small amounts, the soil structure (sand/silt/clay percentages) is usually different from the top and it can lead to problems.

In reality, that doesn't look like a lot of dirt for the size lawn you have and spread out over a couple thousand square feet it won't amount to much so you should be fine. It also won't likely do much to help with leveling unless you use it on a small area, which I wouldn't do for the reasons noted already.
