Winter hairy vetch cover crop legume is a vigorous crop used for fixing nitrogen, biomass production and enhancing organic matter. Winter hairy vetch is an excellent choice for green manure as its low carbon to nitrogen ratio (C:N) allows for quick plant decay and even quicker capture of organic material and nutrients in the soil profile. Winter hairy vetch cover crop legume tends to be very tolerant of variable soil conditions, including low fertility environments. Winter hairy vetch cover crop legume will overwinter in many areas of the country (USDA Zone 3-4) withstanding temperatures down to -25°F to -30°F, especially where snow is likely.
- Strong nitrogen fixing and high biomass potential
- Great to recharge soils during winter by reducing runoff (more water enters the soil profile through pores created by the vetch residue)
- Phosphorus scavenger
- Heavy mulch layer provides excellent weed suppression and erosion prevention
- Excellent option to plant with cereal grain (helps with spring control too)
