Sunn Hemp’s vigorous growth rate and nitrogen fixing capabilities make it an attractive cover crop to build residue, sequester nitrogen, suppress weeds and improve soil health. When planted as a summer annual it regularly produces 2.5 tons of biomass and 120 lbs N/acre. Sunn hemp is a tropical plant and requires a warm soil temperatures germination and when planted it needs at least 45 days to accumulate growth before the first frost. Sunn hemp grows extremely fast in the heat and can reach heights of 6-7 feet in 60 days.  Sunn hemp has also  been found to greatly reduce soybean cyst nematode populations.
