Crimson Clover Cover Crop Plant

Crimson clover is a cool season annual legume used as forage, a green manure crop, and for soil conservation. In no-till, strip-till and organic applications, it is used for soil cover and nitrogen fixation; having the ability to provide from 70-140 lbs of nitrogen for the following crop. Crimson clover offers simple establishment, a higher cold tolerance vs. other clovers, and performance on soils with pH ranges from 4.8-8.2. The suggested pH for crimson clover is between 5.8-6.5. Establish crimson clover six weeks before frost and expect slow fall growth with rapid spring growth.

Key Benefits

  • Nitrogen fixation

  • Rapid spring growth

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.
