Dirt density.
When you dug it out there was more dirt and less air than when you put it back in.
in other words: It was packed really tight at first.
Try !
Because what comes out never goes back in the same way!
Because the soil is made porous by you forking it and stirring it up. when you try to put it back there's still a lot of air pockets inbetween the chunks of soil.
If you stamp on and throw water on it this will go back to what it used to be.
Because you do not compact the dirt as tight.
because the hole that you have dug was full of compacted soil acheived by thousands of years of sediment build up- when you take the soil out and then re-fill it you never quite manage to get the same level of compaction.
before you dig a hole you have a compacted area. during the digging process you are un compacting the dirt . after you put the dirt in you would need to re compact it just right not to have any left over's. It is like a graveyard , the leave the big bumps on top of the plot , in time water and gravity compact it to a level area.
You dug out Compacted dirt, you put back loose dirt.
try giving it a good kicking,that should sort it out
its to do with air in the soil.
