Tree care with AirSpades

 

I’m very excited to have finally purchased my own AirSpade 2000. I’ve been using AirSpades in Arboriculture since 2003 – 14 years – to rehabilitate stressed and/or injured trees, to decompact soil, to introduce soil ameliorations, to excavate near trees whilst minimising damage to roots, to locate and map root systems.

Inonotus obliquus and tomography

Inonotus obliquus, also known as ”sprängticka” here in Sweden, is an interesting fungus. I’ve only seen it in Sweden and only on Birch (Betula spp.). Recently I’ve been comparing the actual decay caused by the fungus with the readings from my Rinntech Arbotom tomograph.
