Terravent
The Terravent system is a soil decompaction and liquid injection tool.
The equipment is transported within a purpose built road trailer which contains the gas cylinders, soil probe, fluid containers and the connecting pipes.
Compacted soils slows root extension and can prevent the free movement of air and water within the soil. This can impede tree root vitality which affects the tree as a whole.
A soil decompaction system injects air into the soil to create fissures so air and water can move more freely.

This system uses a sliding, hand-operated, hammer mechanism to drive a steel spike into the soil. The spike is hollow with a number of holes positioned along its length.
The adjacent picture shows the handle of the central sliding weight being lifted. It is then dropped like a hammer to drive the spike into the ground. Once in place, a hand valve is opened and a blast of gas is sent down the steel probe and into the soil.
The Terravent system uses compressed Nitrogen gas in bottles rather than compressing air with a powered compressor. This means the operation is noiseless and also prevents the risk of oil being trapped into the air by the compressor and sent into the ground.
The system also allows liquids (which can contain Mycorrhizal Fungi) to be injected into the soil during the decompaction process.
