Inceptisol
Weakly to moderately developed soils with diagnostic development insufficient for more developed orders.
USDA Soil Taxonomy order
Profile
- Horizons
- Often include a cambic horizon
- Range
- Wide climate and parent-material distribution
- Texture
- Can vary from coarse to fine
- Mapping
- Not a one-to-one equivalent of all WRB Cambisols
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
- Slope erosion
- Compaction
- Site-specific waterlogging
Stress signs
- Rills
- Dense rooting layers
- Mottling with wetness
Where you'll find it
- Soil survey use
- Site-specific landscape design
