Yellow Blossom Sweet Clover Cover Crop Plant

Yellow Blossom sweet clover is a biennial (2-year) legume that has a deep root system capable of pulling phosphorous and potassium up from the subsoil and redepositing it in the topsoil layer. It is very winter-hardy, drought tolerant, and has an average nitrogen production around 100 lbs/ac. Yellow Blossom sweet clover will produce the greatest summer biomass of any legume in its second production year, but it needs well-drained soils with a neutral pH for optimum growth. It should be noted, however, that Yellow Blossom is a host for soybean cyst nematode.

Key Benefits

  • Biennial

  • Drought tolerant

  • High nitrogen production

  • Attractive to pollinators

Herbicides To Avoid

Corn

  • Atrazine or simazine at >1 lb will be problematic for legumes and mustards unless lots of rain

    • <0.75 lab/A may allow for most legume cover crops, mustards, and annual ryegrass.
    • Atrazine < 1 lb/A can allow cereal grain establishment
  • Mesotrione (Callisto, Lumax, Lexar etc.), flumetsulam (Python) and clopyralid (Stinger, Hornet, SureStart) can be problematic for legumes and mustards like canola and forage radish.

Soybean

  • Chlorimuron (Classic, Canopy, Cloak, etc.), Imazethapyr (Pursuit), and fomesafen (Reflex etc.) could be a problem for fall seeded legume or mustard covers including radish. However, establishment of cereal grains should be OK.
