Screened topsoil

The bags are so expensive. Look at getting it delivered in bulk. Just put out a tarp and get them to drop it on it for you if you are talking 2+ yards.

I probably only need a 1/2 a yard if that and delivery is over $100

Definitely a difference between black earth and screened topsoil. Black earth is peat humus, decayed organic matter. Topsoil is the top of the soil, which contains mostly minerals (which provide structure) along with some organic matter. Topsoil is better for leveling. Can usually find bags of cheap topsoil somewhere, but be wary - cheap topsoil may contain weed seeds. Some things are worth paying for.

If you're trying to level something, the amount of dirt you need will likely be impressive. As you've seen with using back earth, a bunch of it doesn't do much.

Try to roughly measure the area and estimate the amount of dirt you need. I was relevelling an area near my gardens and it has devoured 6 yards so far, and I think I'm about half done.

Well, if delivery is too expensive, you'll have to pick it up yourself. Perhaps rent a pickup truck from U-Haul. That should be cheaper than the $100 delivery fee you mentioned.

Is screened topsoil the same as garden soil?
