Soil compaction is one of the primary causes of urban plant failure. When growing in compacted soil, the tree roots are, in effect, suffocated. They can’t absorb the nutrients and there is no air available in the soil that the tree needs to live. Using an air excavation tool it is possible to de-compact soil within the root zone.
The Arb-Ex has been designed with de-compaction in mind. Firstly, the Arb-Ex nozzle allows for easy soil stirring. The overall length of the Arb-Ex is shorter than similar tools; this means that the tool can be operated from a comfortable height, minimising repetitive strain injuries. With the addition of the auxiliary handle, it further increases operator comfort and controllability.
Once the soil has been de-compacted, mulch can be stirred into the soil to add nutrition.
