Birdsfoot Trefoil with Red Clover
Lotus corniculatus L. and Trifolium pratense L.
grassThis is a pasture and cover crop blend combining two nitrogen-fixing legumes. Birdsfoot trefoil is a deep-rooted, drought-tolerant perennial legume, while red clover is a shorter-lived but highly nutritious nitrogen-fixer. Together they create a productive, sustainable forage mixture valued for livestock grazing, hay production, and soil improvement.

Germination & Seedling
4-8 weeksSeeds germinate in 7-14 days; seedlings develop cotyledons and first true leaves. Small, delicate plants vulnerable to competition and drought.
Keep soil consistently moist but not waterlogged. Control weeds aggressively. Avoid grazing or cutting in first 6-8 weeks.
Vegetative Establishment
6-12 weeksPlants develop deep root systems and establish nodule-forming relationships with Rhizobium bacteria. Red clover grows upright; birdsfoot trefoil forms lower, spreading mats.
Reduce irrigation frequency as plants establish. Do not graze or cut during first season to allow root development. Monitor for legume-specific pests.
Flowering & Forage Production
8-12 weeks (repeats seasonally)Birdsfoot trefoil produces yellow flowers in distinctive bird's-foot-shaped clusters; red clover produces dense pink-purple flower heads. Both fix nitrogen via root nodules.
For hay, cut at early bloom stage for maximum nutrition. For grazing, allow 4-6 inch growth before livestock access. Rotate grazing to prevent overuse.
Mature Stand Management
Year 2 onwardsEstablished mixture provides sustained forage production over multiple years. Red clover contribution decreases after year 2-3; birdsfoot trefoil dominates in mature stands.
Reseed red clover every 2-3 years to maintain mixture balance. Apply phosphorus/potassium if soil test warrants. Control broadleaf weeds.

Common Pests
-
Rotate pastures to disrupt pest cycles; time grazing to avoid peak feeding periods; no chemical control typically needed in diverse pastures
-
Rotate grazing timing; mow infected fields early and allow regrowth; promotes plant vigor and reduces weevil survival
-
Usually not problematic in mixed stands; maintain diverse vegetation to support predators; rarely requires intervention
-
Monitor in early growth; predatory insects usually control populations; remove heavily infested plants if needed
-
Ensure good drainage; improve air circulation; avoid excessive spring moisture; rotate fields; no chemical control for organic systems
Uses
Livestock Forage & Pasture
CulinaryBoth legumes provide high-quality forage for cattle, sheep, goats, and horses. Red clover is particularly palatable and nutritious for dairy production; birdsfoot trefoil is less bloat-prone and drought-tolerant for extensive grazing systems. [source]
Nitrogen Fixation & Soil Improvement
HouseholdBoth species form symbiotic relationships with Rhizobium bacteria in root nodules, converting atmospheric nitrogen into plant-available forms. This reduces or eliminates the need for synthetic nitrogen fertilizers while improving long-term soil fertility. [source]
Phytoestrogen Content
MedicinalRed clover contains isoflavones (formononetin and biochanin A), compounds with potential hormonal effects studied for animal and human health applications. Historically used in herbal traditions. [source]
Pollinator & Wildlife Habitat
WildlifeAttractive flowers support bees, butterflies, and other beneficial insects. Dense cover provides habitat for ground-nesting birds and beneficial arthropods. Increases biodiversity in agricultural systems. [source]
Hay & Silage Production
CraftThe mixture produces excellent quality hay and silage for winter feeding. Early-bloom harvesting preserves nutritional value; proper curing and storage maintains feed quality for sustained livestock nutrition. [source]

Harvest Tips
For hay: Cut at early bloom stage (early flowering) for maximum nutritional value; moisture should be 15-20% for baling. For grazing: Allow 4-6 inches of growth before turning livestock in; rotationally graze to prevent overgrazing and allow 3-4 week recovery periods. Both species can be harvested 2-3 times per season in good conditions. Red clover is typically harvested by year 1-2; birdsfoot trefoil provides longer-term sustained production.
Fun Facts
- 🌱 Birdsfoot trefoil's seedpods resemble a bird's foot, which inspired its common name. The plant can survive 5-8+ years, making it one of the longest-lived pasture legumes.
- 🌱 Red clover was so valued by farmers historically that it was sometimes called 'the foundation of American agriculture.' It contains more crude protein than many grain crops and actively improves soil for following crops.
- 🌱 This mixture is a key component of organic and regenerative agriculture systems worldwide because it eliminates the need for synthetic nitrogen fertilizers while building soil health through biological nitrogen fixation.
