This. . . doesn't sound convincing to me.
Soil displacement is a function of machine weight AND surface area of tires/treads. Additionally, I'd expect the sharp edges of steel treads to disturb soil much worse than a similarly-weighted tractor with rubber tires.
Without doing extensive calculations, my anecdotal evidence is that I've seen bulldozer track "scars" from a single path that are decades old, while the damage from thousands of bicycles collectively veering from a paved path onto grass appears to heal itself in a year or two.

- bluGill 8y agoYou say the bicycle healed in a year, but you didn't measure that (this is a guess, but is seems reasonable). It isn't enough to say the grass appears green, is it as thick and growing as fast as untouched grass nearby. A single track every 30 meters where nothing grows is less impact on the overall field's growth than 30 tracks every meter where things still grow but not as well.
- thatcat 8y agoThe damage to the soil occurs mostly when turning, especially 180 degrees at the row end. The extent of damage depends on the wheels ability to articulate to the proper angles. The tracked vehicle can't change angles and pushes everything around. A bicycle is a cycle and has none of the turning drag encountered in 4 wheel vehicles or skid steers.
