Before and After BioChar injection
How we do this?
We use this machine, the revolutionary Vogt Geo Injector
VOGT Geo Injector pro
The powerful professional device for soil aeration and injection technology
Firstly, we drill down into the soil approximately 65cm.
We then inject high pressure air at 7bar (100psi), this de-compacts the soil and creates voids
Injection of enriched biochar
We then inject Enriched Biochar into the voids, this further de-compacts but fills the voids with material that does not degrade allowing air and water to pass easily to the root ball of the tree.
Improved Water Retention
Water falling on the gound now flows into the voids, as Biochar is honeycomb shaped it absorbs the water. Holding it for when the tree needs it.
Trees require a soil with good aeration after Soil Decompaction this allows air to circulate freely around the root ball.
Add sunlight and water to create a healthy tree
An example where we apply
On average we inject 1kg of Enriched Biochar blend per 1m2 of ground.
Each injection point connects to the next, creating mini soakaways allowing drainage and aeration across the complete area injected.
As seen on the
The London Borough of Bexley’s Tree and Nature Conservation team called upon Apex Soil Solutions;
to bring back to good health the Bexley Charter oak.
Despite having a root protection zone erected, having mulch applied every year and even air-spading in the past, the Charter Oak was showing diminishing vitality and a reduced leaf area index.
Apex used their cutting edge Geo-Injector to drill down to 1.2m deep all around the tree base. Apex was able to decompact the soil and create pockets to be backfilled simultaneously with enriched biochar that completely encompassed the root zone.
The oak transformed to full health within 12 months.
