Organic & Peat Soils
Soils high in organic matter that hold very large amounts of water but can subside and become water-repellent when dried.
Soil condition
Profile
- Organic matter
- 20%+
- Water holding
- Very high
- Bulk density
- Very low
- Risk
- Subsidence and hydrophobicity
Water & soil targets
- Moisture (VWC)
- Field capacity often 50%+
- Salinity tolerance
- Moderate
- Drought tolerance
- Hard to rewet once dry
Keep from drying fully.
Problems to watch
- Subsidence
- Water repellency
- Nitrogen release swings
Stress signs
- Dry crust that won't rewet
Where you'll find it
- Wetland-edge sites
- Specialty agriculture
