Tillage Sunn™ Sunn Hemp Warm Season Legume
You can purchase Tillage Sunn "straight up" or in a mix. Tillage Sunn comes in 50 pound bags.
As a warm season cover crop legume, Tillage Sunn™ increases soil organic matter, provides nitrogen, grows in low fertility sandy soils, and does not harbor most types of nematodes most destructive to crops in North America, generally found in sandy soils in Southern growing regions.
Tillage Sunn™ (Crotalaria juncea L.) is native to the tropics, but grows in North America as a summer annual. It can produce over 5,000 pounds of biomass and up to 140 pounds of nitrogen per acre, depending on conditions.
Inoculant Required: EL Type/Garden Combo
Tillage Sun Fact Sheet
Because of its fast growth, Tillage Sunn only needs 8 to 12 weeks of frost-free growth conditions to achieve good results. This makes it an excellent choice where there is a relatively short window following cash crop harvest in the fall and the onset of winter.
Where conditions are favorable, Tillage Sunn™ can provide the benefits of a winter legume prior to a killing frost in the fall, and also in the summer after the winter crop has been harvested.
Tillage Sunn™ grows rapidly and achieves economic value as a cover crop in about 60 days. Tillage Sunn is killed by the first frost. The management cue for termination (burn down) is when the first flower buds begin to appear.
Tillage Sunn™ adds significant nitrogen to depleted soils, such as following small grain harvest, as a break crop in sugar cane production, and with vegetables grown in loose sandy soils, where it also adds up to two and a half tons of organic matter.
Tillage Sunn nodulates readily with native cowpea type rhizobia.
