SF 167 Summer Grazer is a Soil First™ cover crop mix consisting of Sorghum x sudangrass, Sunn hemp and the Soil First Select Radish.  SF 167 needs to be planted after soil temps reach at least 60° F or higher in late spring through late summer to take advantage of the warm season species in the mix.  This mix tolerates a wide range of conditions – poor soil, low pH, hot and extremely droughty environments.  Formulated to maximize biomass growth when planted early.

Planting window:  After last frost in the spring to 8 weeks prior to first frost date in the fall (soil temps need to be above 60° F)

Seeding rates:

  • Seed 25-30 lbs/acre alone with a drill (7.5″ spacing)
  • Broadcast/Aerial:  Not recommended
  • For forage 25-30 lbs/acre

Seeding depth:  ¼” to 1″ deep

Comparable setting on drill chart:  Wheat (use large box)

Germination soil temperature:  +60° F

DM tons/acre:  2-5

Considerations:  Sunn hemp will flower when temperatures allow across the country, but will only produce seed in the deep south (below 28 degree north latitude – think Orlando, FL and Corpus Christi, TX ). Sunn hemp is known to contain toxic alkaloids harmful to grazing animals, present in the seeds only. Sunn hemp may not be ideal in 100% of no-till systems as any leftover residue can be tough to plant through the following spring . Sorghum x sudangrass presents the opportunity for prussic acid toxicity, especially after fall frosts. To maximize forage production, nitrogen applications are recommended. However, those same fertility supplements can pose an increased
threat of elevated nitrates in sorghum x sudangrass after plants are stressed.

Benefits:  scale 1-5, 5=best

  • Compaction Alleviation      4
  • Weed suppression               5
  • Biomass production            5
  • Erosion control                    4
  • Disease/Pest control          4
  • Pollinator/Beneficials        4
  • P & K Cycling                       3
  • Ease of Establishment       3

Termination:  Any frost will terminate sorghum x sudangrass and sunn hemp. Small sunn hemp (less than 3-4’) can be effectively controlled with light rates of glyphosate. Taller plants require higher rates and equipment to allow for proper coverage. Radish will terminate with multiple nights in the teens. If radish over winter, glyphosate and 2,4-D provide effective.
