This should take more testing to be sure ...
I was making a steve's cart tree farm and thought I'd use xycraft soil instead of using bonemeal fertilizer. I knew I could plant the oak saplings on xycraft soil so I went for it.
I stacked the soil 5 deep at each of the tree locations I knew the cart would set up. Turned on the cart and it totally ignored the xycraft soil.
Darn.
I got lazy and didn't pick up all my xycraft soil, I just dug out the top spot and put in dirt. Steve's cart recognized dirt and went to town. It didn't have any fertilizer.
From the results I'm getting, I'm going to go out on a limb and say that xycraft soil under regular dirt confers the bonus and solves the problem with some types of tree and seed that don't like his soil. The boost to growing appears to be fine. Darn trees are sprouting like crazy and it's having the effect I wanted. Didn't realize the xycraft soil would work if the plant wasn't directly on top of the stuff, just needs to be in the same block?
Now I'm thinking the xycraft soil effect works for every block above the soils even is another type. So I could stack the xycraft soil 4-5 deep and then proceed to make a tower of regular farms and each level of the tower benefits from the soil.
