Extending the grazing season while protecting and building the soil is a great benefit of this species. The biomass N content can range from 1.3-2.4% and varies depending on the amount of residual N left from the previous crop. Reports of annual ryegrass having the potential to scavenge up to 200 lbs of residual N/A/yr have been recorded. Ryegrass can be very successfully broadcast into established row crops. Winter killed ryegrass can still provide weed suppression, soil protection and trap residual N until spring. Ryegrass attracts very few pest insects that could pester the next crop. With lower needed seeding rates per acre you will spend less on freight and your applicator can remain in the drill or in the air longer. Annual ryegrass has deep roots, but when considering it for more northern areas, it must be established prior to hard freezing in order to have the best chance of winter survival.
Drill seed at 0.25" to 0.5" depth at 15-20 pounds per acre, or broadcast at 20-30 pounds per acre.
