Very good example of how sod can monopolize all nutrients and organic matter. I wonder if earthworm activity was detered chemically , thus producing excellent green growth with no soil development below.

since first seeing this I'm seeing tons of old trees that were blown down in the storms (on the news) and it is amazing..some have a 16' uprooted area and the root area is barely a foot or two deep.
Every day there are more news photos of trees on houses and cars..and they are huge..but you are right, some have very little root
Bloom where you are planted.
My guess from experience is that the landscapers didn't take the time to loosen up or improve the soil it was on so it remained as compacted as when the construction crew left it. A dozen feet pounding dirt all day for a year with machinery to boot can make for practically rock hard dirt below. Even if you do layer your good soil on top of that it's always good to come through with some sort of aeration device something... Poor tree. You can even see where it's root ball sat when they planted it.. Kind of a pity that such a large tree might be lost because someone couldn't take 20-30 minutes to work the existing earth.
Wow, what a reminder. When we moved into our house 6 years ago, we followed the advice from several authors, and just ignored the base dirt, laid down cardboard, and built up layers of compost, hay, straw, manure, etc. When we had to move those beds two years ago to build our greenhouse, the ground under the beds still looked and felt like concrete. Three years of gardening and watering hadn't even started to penetrate the hard subsoil.
So yes, I now know that we have to loosen the ground, or dig out a sunken bed, before we can plant anything and expect it to grow.

Not so much as the constant irrigation and fertilizer. If you feed and coddle the plant, it is not going bother to build roots because it doesn't have to. The tree was just doing what it was incentivized to do.
