Arboriculture and urban greening
Biochar for urban trees.
Specified around the site.
Urban tree projects combine soil, drainage, rooting volume, loading, irrigation, planting design and maintenance. Biochar may form part of a specification, but it should be selected as one component of the complete tree and soil system.

What must be defined.
- Site and soil assessment
- Tree-pit or treatment design
- Carbon source and grade
- Blend components and ratio
- Application rate and method
- Establishment and monitoring plan
Design for the whole tree system
A carbon product cannot compensate for inadequate soil volume, poor drainage, unsuitable species selection or absent aftercare. PCS material design should sit within a competent arboricultural and landscape specification.
New planting and established trees differ
Material can be incorporated throughout a new soil or delivered more selectively around established roots. These routes require different particle, handling, dosing and installation decisions.
Use project evidence carefully
Outcomes should be measured against baseline conditions and interpreted with weather, irrigation and maintenance in mind. PCS will not present development intent as proven field performance.
Clear answers.
No invented claims.
PCS separates what the material is designed to do from what has been demonstrated in the actual application.
How much biochar should be used around a tree?+
There is no responsible universal rate. It depends on the material, soil volume, formulation, tree, installation method and professional specification.
Can PCS formulate material for a tree-pit specification?+
Yes. PCS can assess the required carbon, particle range, mineral blend and delivery format with the project team.
Are TerraLith products fertilisers?+
TerraLith products are application-led carbon and mineral formulations. The status and composition of each product depend on its confirmed specification.
