Urban Tree Soil (R)
Suitable For:
• Urban Tree Planting
• Preventing Subsidence
• Compaction Resistant Tree Planting Soil
• Tree Planting in Car Parks
• Preventing Pavement & Road Damage
• Tree Planting in Hard Landscaping Environments
Often referred to as ‘Amsterdam Tree Sand’ or ‘Structural Tree Sand’, Bury Hill Urban Tree Soil (R) has been specifically created as an anti-compaction soil for tree planting in urban areas, car parks and hard landscaping environments.
Bury Hill’s Urban Tree Soils are produced with high levels of sand for the structural and drainage properties required for these types of soils. The grading of the sand is therefore important, and our Urban Tree Soil (R) utilises a washed medium sand with a narrow particle size distribution to ensure sufficient porosity levels are maintained when the material is compacted.
Laboratory testing confirms, when compacted, the permeability of our Urban Tree Soil (R) was high at 135mm/hr and is considered satisfactory for urban tree planting and tree planting in hard landscaping environments.
Furthermore, Urban Tree Soil (R) is adequately supplied with organic matter and most major plant nutrients with the exception of total nitrogen, which can be remedied by a routine fertiliser application*
Both the horticultural and geotechnical properties of this material are also confirmed suitable for the proposed application, and our Urban Tree Soil (R) can be installed to a maximum depth of 600mm.
We recommend that our Urban Tree Soil (R) should be used in conjunction with our Washed Tree-Pit Subsoil (R).
You may also wish to consider our Urban Tree Soil (S), which has a moderately high permeability and is adequately supplied with all major plant nutrients.
FERTILISER RECOMMENDATIONS*
To address the low nitrogen, our soil scientists recommend applying and incorporating the compound controlled release fertiliser: ICL Osmocote PrePlant at a rate of 70 g/m2 into the upper 400mm layer of rootzone before consolidation.
SOIL CONDITIONER
For enhancing the water and nutrient retention capacities of this soil, consider applying and integrating our TerraCottem Universal Soil Conditioner into each layer of the Urban Tree Soil (R) prior to consolidation.
Urban Tree Soil (R) is tested for use as a Structural Tree Planting Soil in hard landscaping environments by the UK’s leading Soil Science and Landscape Engineering Consultants, Tim O’Hare Associates
