Key Benefits
Reduce Soybean Cyst Nematode
Weed Suppression
Substantial Bio-Mass
Sunn Hemp is a tropical legume that can produce 120 lbs/ac of nitrogen and transfer residual phosphorous and potash from the subsoil to the topsoil. In just 60 days, sunn hemp can grow up to 6 feet tall, creating up to 4 tons of organic matter. Primarily used in cover crop summer mixes after small grains, sunn hemp is an excellent forage for grazing mixes. Sunn hemp is excellent at weed suppression and has been shown to reduce soybean cyst nematode. Well-drained, sandy soils with a pH between 5 and 8.2 are preferred for planting sunn hemp with a soil temperature of 65°F – sunn hemp will terminate at 28°F and below.
