Increasingly we see trees under stress in our urban environment.

The Terravent machine is a pneumatic machine used to improve soil condition and to treat plant roots.

Soil can be decompacted and aeriated using the Terravent machine. Liquid media can also be injected into the soil to feed the roots of a failing tree. In a perfect situation, a woodland environment, trees have access to fungi called Mycorrhiza in the soil. There are several different kinds of Mycorrhiza that occur in the soil. If for any reason the natural balance of Mycorrhiza is upset by building work (construction) or compaction, the absorbtion of Mycohorrizas can slow down. We use the Terravent to inject Mycorrhiza into the soil using a high power jet of nitrogen gas. This decompacts the soil and then feeds the Mycorrhiza into the root area. This technique is being used at The Royal Botanic Gardens, Kew, to preserve their mature tree stocks.

AIRSPADE
The airspade can be used in Root Collar investigations. If the health of a tree is suspect we can elect to use this tool to investigate the health of the roots. This system is non invasive and can be very effective with regards to tree health diagnosis.

The Airspade can also be used to vertically mulch within the root protection areas of mature trees.
