Silt Profile
Silt-rich profile with substantial water retention but vulnerability to sealing and erosion.
Physical soil profile descriptor
Profile
- Texture
- Confirm whether actual class is silt or silt loam
- Structure
- Weak aggregates are vulnerable to disturbance
- Capillarity
- Fine pores can sustain upward water movement
- Drainage
- Layering and compaction affect aeration
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
- Surface crusting
- Wind or water erosion
- Wet compaction
Stress signs
- Sealed surface
- Sediment movement
- Slow infiltration
Where you'll find it
- Root-zone assessment
- Landscape drainage planning
