White Oats are a fast-establishing, cool-season grass cover crop known for rapid biomass production, weed suppression, and erosion control. Often used as a nurse crop or in mixes with legumes like vetch or clover, White Oats provide a dense canopy that protects soil and improves tilth. They are particularly effective at scavenging residual nitrogen and breaking up compacted soils with fibrous roots. In California, they are best fall-planted and terminated in late winter or early spring before seed set.
Seeding rate: 60–100 lbs/acre (solo), 30–60 lbs/acre (in mix)
Days to Germination: 5–10 days
Days to Maturity (Harvest or Termination): 60–90 days (for biomass), 100–120 days (to full grain maturity if allowed to head)
Planting window: Fall (Sept–Nov), early spring in some regions
Growth cycle: Annual – quick-growing, winter-killed in colder zones
Soil benefit: Organic matter builder, weed suppressant, nitrogen scavenger
Preferred soils: Well-drained; tolerates a range of conditions
Best for: Biomass production, erosion control, soil structure improvement
Avoid if: You require a winter-hardy or perennial cover
