Sand Profile
A sand-dominant constructed or natural profile; particle grading and layer interfaces determine behavior.
Physical soil profile descriptor
Profile
- Texture
- Sand dominance does not specify grain-size distribution
- Retention
- Usually limited plant-available storage per depth
- Interfaces
- Fine-over-coarse layers can perch water
- Testing
- Measure infiltration and retention in installed profile
Water & soil targets
- Moisture (VWC)
- Site-calibrated; measure field capacity and dry-down
- Salinity tolerance
- Measure salts in water and pore solution; no tolerance is implied
- Drought tolerance
- Storage and plant response depend on profile and vegetation
Calibrate to the installed material and depth. Do not infer an irrigation threshold from the profile label.
Problems to watch
- Rapid drying
- Localized water repellency
- Nutrient leaching
Stress signs
- Dry patches
- Uneven infiltration
- Plant wilt where vegetated
Where you'll find it
- Root-zone assessment
- Landscape drainage planning
