Mechanics of Core Aeravation vs. Core Aeration

What happens here

The presenter explains the mechanism of core aeravation, also known as 'soil fractionation'. It involves driving solid spikes into the ground, which then vibrate laterally and vertically below the surface. This action loosens 100% of the soil in the work area without removing any cores or plugs. This is contrasted with traditional core aeration (plug pulling), which uses hollow tines to jab into the ground, remove soil plugs, and leave them on the surface to decompose. The video shows examples of removed plugs and highlights how running over these plugs can re-compact the soil.

Goal: Explain the difference in how core aeravation and core aeration (plug pulling) work.
