The dinosaurs did leave droppings to enrich the soil, combines don’t.
Maybe there were giant earthworm type creatures that kept the soil aerated and friable.If they were soft bodied ,with no skeletal sutem or exoskeleton ,maybe there is no physical evidence they ever existed.
Just think of the size of a dung beetle back then.

Now that was unique.
And quite interesting.

Interesting.

The American prairie supported herds of tens of millions of bison. Bison are big, like a ton each. But not as heavy as the modern wheat combine. The prairie was replaced by the modern wheat belt that stretches from Oklahoma to southern canada. So what was the prairie that was trod upon by the bison is now "compacted" by modern wheat combines.

Its hard to imagine a world without grass, but oddly enough grasses did not evolve until late in plant evolution. Grass only appeared at the tail end of the Cretaceous. So for most of the 130 million years that dinosaurs existed there were no grasslands, no pairies, and savannahs. Just forests or deserts. So the dinosaurs were not exactly doing the same thing as either wheat combines do or that the bison used to do. They were not grazing fields of grass, nor mechanically 'grazing' fields of wheat (which is a domesticated type of grass), but eating off of trees, and giant ferns.Would that make a difference? I dunno. But as MissL said the dinos would have laid down 'organic fertilizer' as they went. And maybe dung beetles would work it into the soil and uncompact the soil.

And there were no prairies in dinosaur times, for yet another reason:
