90/10 Sand Mix
A nominal blend, often 90% sand and 10% amendment by volume; verify the actual recipe.
Constructed root-zone blend
Profile
- Recipe
- Ten-percent component may be peat or another material
- Basis
- Volume versus mass must be documented
- Testing
- Test finished blend rather than ingredients alone
- Aging
- Organic decomposition changes pore properties
Water & soil targets
- Moisture (VWC)
- Site-calibrated; measure field capacity and dry-down
- Salinity tolerance
- Not determined by this label; measure EC and relevant ions
- Drought tolerance
- Depends on usable storage, rooting depth and vegetation
Measure retention, infiltration and layer depths in place. Texture or construction labels do not define a universal irrigation threshold.
Problems to watch
- Blend inconsistency
- Organic matter accumulation
- Hydrophobic dry spots
Stress signs
- Uneven infiltration
- Soft wet patches
- Localized drying
Where you'll find it
- Sports root zones
- Golf construction
