Planting trees in urban areas is an important part of city life today. As with all plants, trees absorb carbon dioxide and produce oxygen making our towns and cities safer, cleaner and healthier places to live.
Amsterdam Tree Sand is the generic term used for a sand based structural growing media used for planting semi-mature trees in paved urban environments developed by Dutch universities over thirty years ago.
The ideal behind Amsterdam Tree Sand or Urban Tree Soil is to create a growing medium that allows strong root growth and development whilst also preventing damage to roadways and pavements by mitigating subsidence issues and resisting compaction in highly trafficked vehicle and pedestrian environments.
Urban Tree Soil is created by blending a selection of specifically graded silica sand particles (which create sufficient pore space in the growing media allowing oxygen and moisture to permeate the root zone whilst also allowing strong root development) with the addition of matured quality assured organic material providing the essential nutrients required to facilitate good growth.
Benefits of Tree Planting Schemes
- Improve local biodiversity
- Reduce smog and air borne dust and pollution
- Positive impact on asthma symptoms
- Aesthetically pleasing and calming
- Natural rain cover in storms
- Cool local climate in the summer
- Warm local climate in the winter
Benefits of Urban Tree Soil / Amsterdam Tree Sand
- Resists root compaction by pedestrians and vehicles
- Provides stability and prevents subsidence for the tree and root ball
- Offers ideal drainage
- Encourages healthy tree growth
Directions For Use
In a generic planting scheme it is recommended to use approximately five cubic metres of urban tree sand for each tree planted dug to a depth of one metre.
The soil should be packed down in 250-300 millimetre layers with a 150 millimetre top dressing of binding sand to assist with drainage.
