Cambisol

Moderately developed soils showing subsurface alteration but lacking stronger diagnostics of other groups.

WRB Reference Soil Group

Profile

Diagnostic
Commonly a cambic horizon
Distribution
Occurs across diverse climates and parent materials
Texture
Not specified by the group name
Fertility
Depends on parent material and leaching

Water & soil targets

Moisture (VWC)
Site-calibrated; measure field capacity and dry-down
Salinity tolerance
Not inferable from soil classification; test EC, sodicity and water chemistry
Drought tolerance
Not inferable from taxonomy; measure accessible storage and plant response

Soil orders and WRB groups are not textures. Determine horizon-specific retention, field capacity, drainage, rooting depth and seasonal hydrology before setting irrigation triggers.

Problems to watch

  • Erosion on slopes
  • Compaction
  • Locally restricted drainage

Stress signs

  • Rills
  • Dense traffic zones
  • Mottled wet subsoil

Where you'll find it

  • Land capability review
  • Site-specific planting assessment
