Soil Compaction and Core Aeravation as 'Tilling'

What happens here

The presenter highlights that soil compaction is a common issue in most yards, preventing roots from growing deeply. He compares core aeravation to 'tilling the soil,' a practice common in farming to loosen soil for new crops. Unlike tilling, which flips the ground upside down (as shown with a tiller on a yard), core aeravation loosens the soil without inverting it, allowing roots to penetrate deeper and grass to 'explode' and grow vigorously. He explicitly warns against tilling a yard due to the extreme disruption it causes.

Goal: Explain soil compaction and the benefits of core aeravation in loosening soil without tilling.
