Loam Profile
A profile described by loamy texture, with behavior strongly affected by structure and depth.
Physical soil profile descriptor
Profile
- Texture
- Loam mixes sand, silt and clay within defined limits
- Layers
- A loamy surface can overlie a restrictive subsoil
- Storage
- Available water depends on organic matter and rooting depth
- Management
- Protect aggregates from wet traffic
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
- Compaction
- Poor subsoil drainage
- Surface erosion
Stress signs
- Persistent puddles
- Shallow roots where vegetated
- Rills or crusting
Where you'll find it
- Root-zone assessment
- Landscape drainage planning
