- 45 to 90 lb/acre or 50 to 100 kg/ha
Frost tolerance
- -8°C
Cover Crops and Intercrops Legumes
Forage Pea
Légumineuses
Features

Frost tolerance
- -9°C
Cover Crops and Intercrops Legumes
Forage Soybean
Légumineuses
Features
- New soybean genetics for indeterminate growth
- Can grow to a height of 6-7ft. (10-12 t DM/ha) if the season is long thus increasing the potential nitrogen return
- Highly resistant to drought
- Not susceptible to Sclerotinia as flowering is very late

Frost tolerance
- -2°C

- Grasslands Huïa is most frequently used, with a low, creeping growth habit
- Shallow stoloniferous root system
- Small seeds establish readily
- Attracts pollinators
Seeding rate
- 5 to 7 lb/acre or 6 to 8 kg/ha
Frost tolerance
- -15°C
Cover Crops and Intercrops Legumes
Crimson Clover
Légumineuses
Features
- Winter annual
- Annual if seeded in spring
- Biennial if seeded in fall
- Rarely overwinters in our conditions
- Establishes more rapidly than perennial clovers
- Small seeds fill in holes easily
- Prostate growth
- Suited to cool, wet conditions
- Not very competitive
Seeding rate
- 13 to 18 lb/acre or 15 to 20 kg/ha
Frost tolerance
- -13°C
Cover Crops and Intercrops Legumes
Red Clover
Légumineuses
Features
- A central tap root with secondary lateral roots
- Two types: single or double cut
- Single-cut clover establishes more slowly and so is less likely to overtake the crop when intercropped in cereals
- Planted in spring, the potential for abundant biomass production in fass is high
Seeding rate
- 5 to 13 lb/acre or 6 to 15 kg/ha
Frost tolerance
- -15°C
Cover Crops and Intercrops Legumes
Common Vetch
Légumineuses
Features
- Annual plant, not winter hardy
- Grow best in sandy soils
Seeding rate
- 36 to 54 lb/acre or 40 to 60 kg/ha
Frost tolerance
- -8°C
Cover Crops and Intercrops Legumes

Légumineuses
Features
- Winter annual
- Annual if seeded in spring
- Biennial if seeded in fall
- Regrowth after cutting
- Drought-tolerant when well established
- Continues to grow late into the season
Seeding rate
- 18 to 27 lb/acre or 20 to 30 kg/ha
Frost tolerance
- -8°C
