Can you show me a pic of how the air knife is used to decompact?
The pdf's suggest there's no improvement, another guy I know said from his experience it definately worked and showed a lot of improvement. However in Sydney they shy'd away from using it coz they reckon it tore apart the fine hairy root system when the clumps of soil fracture.
So, if all is accurate, forget injecting, start soil drench and mulch and all is OK. Hmmm, dunno, to break the soil up and get some air down there sounds like a benefit. |
