Austrian Winter Pea
Austrian winter pea is a winter-adapted field-pea type grown for nitrogen fixation and readily decomposable biomass. The California NRCS publication explicitly identifies Austrian winter pea within its field-pea profile; performance and winter survival vary with environment and cultivar.
Profile
- Identity
- A winter field-pea type within Pisum sativum, rather than a separate species.
- Season
- Cool-season annual legume.
- Height
- The California chart describes field peas approximately 20–28 inches tall.
- Seeding depth
- The California chart lists 1–2 inches; local seedbed and cultivar guidance may differ.
- Nitrogen
- Fixes atmospheric nitrogen when effectively nodulated.
Water & soil context
- Moisture (VWC)
- The cited publications do not provide numeric volumetric water content sensor targets.
- Salinity tolerance
- The California chart rates salinity tolerance as poor; it does not provide a numeric threshold.
- Drought tolerance
- The California chart rates field-pea drought tolerance as good.
Illustrative monitoring-depth band

Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.
These qualitative ratings are not irrigation schedules or guarantees of performance under water deficit.
Problems to watch
- Pea aphids can colonize the crop.
- Can host Sclerotinia minor.
- Coordinate termination with the following crop and prevent unwanted seed production.
Stress signs
- The cited sources do not provide a reliable Austrian-winter-pea-specific list of visible stress symptoms.
Where you'll find it
- Cover crop
- Green manure
- Forage
