Cover Crop Attributes & Seeding Rates

Daikon Radish

  • Deep taproot that breaks up compaction and scavenges nutrients, especially nitrogen.
  • Fast growth, good heat and drought tolerance.
  • Mixes well with small grains and grasses.

SEEDING AND MANAGEMENT:

  • Plant radishes from early August up until 3 weeks prior to first frost.
  • They can be broadcast or drilled shallow at ¼” to ½”. They work well in mixes or can be seeded alone.
  • Seed at 6-8 lbs/A straight or 2-4 lbs/A in mixes. Allow 7 days for emergence.
  • Radishes will winterkill when temperatures reach 22° F.

Austrian Winter Peas

  • Excellent nitrogen producer. Awesome mix partner with Daikon Radish
    (see Groundbreaker Mix)
  • Will not overwinter in low temps without snow cover.
  • Lots of biomass and good forage quality.

SEEDING AND MANAGEMENT:

  • Plant peas from early August up until late September
  • Seed at 25-30 lbs/A at ½’ to 1” deep. Works best when drilled.
  • Seed size is 3000 to 3500 seeds per lb. Use Winter Pea inocualnt for best results.
  • Easy to terminate with herbicide. Low C:N ratio provides rapid breakdown of pea residue.

Crimson Clover

  • Winter annual, excellent N producer, fibrous root system good for soil building.
  • Increases soil moisture holding capacity.
  • Works well in mixes with annual rye, radishes, or small grains (see Nutribuilder Mix).

SEEDING AND MANAGEMENT:

  • Plant Crimson at least 3 weeks prior to first frost. If planted very early, crimson will produce a seed head and will not overwinter.
  • Seed at 10-12 lbs/A at ¼” to ½” depth. If broadcast, roll into a firm seed bed. Allow 7 days for emergence.
  • Easy to terminate with herbicide.

Annual Ryegrass - Winterhawk

  • Best Ann. Rye variety for winter hardiness, #1 rated in the Ohio State cover crop trials.
  • Deep fibrous root system with a ton of subsoiling roots to break up compaction.
  • Good N scavenger and erosion preventer. Great in mixes (see Nutribuilder Mix).
  • Uniform maturity that will break dormancy evenly in the spring for easier burndown.

SEEDING AND MANAGEMENT:

  • Plant 3 weeks before first average frost, can be drilled shallow or broadcast at 10 lbs/A.

TERMINATION RECOMMENDATIONS:

  • For effective burndown, plants should be actively growing with 6-9” in height and preferably before the first node has developed.
  • Daytime air temperatures should be above 60° F with night time temps above 40° F. If night time temperatures drop below 40° F, wait 3 days before spraying. Always finish spraying 4 hours prior to sunset.
  • Apply Glyphosate at 1.5 – 2.0 lb a.e./A plus AMS and LI-700 ph adjusting surfactant. Do not tank mix additional residual or pre-emerge herbicides with Glyphosate. 2,4-D can be added for additional broadleaf control.

Cereal Rye

  • Very winter hardy that can be seeded very late, seeds will germinate in soil temps as low as 35° F.
  • Fibrous root system that adds organic matter, scavenges N, loosens the soil, and prevents erosion.
  • Great for weed suppression, fast spring growth.

SEEDING AND MANAGEMENT:

  • Plant from late August up to mid-November. Emergence will take more time in cooler soil temperatures.
  • Available in bags or mini-bulks. Similar seed size as wheat.
  • Seed at 50-60 lbs/A at ½” to 1 ½”depth. Avoid seeding depth over 1 ½”. Can be broad cast or drilled.
  • Easy to terminate with herbicide.

Fall Barley - Valor

  • Dual purpose as a cover crop and forage crop. Very winter hardy.
  • Produces large volumes of biomass adding organic matter and scavenging nutrients.

SEEDING AND MANAGEMENT:

  • Plant 3 weeks prior to average first frost.
  • Seed at 50-80 lbs/A at ½” to 1 ½”depth.

Oats

  • Rapid fall growth with shallow fibrous root system. Will not root deep in the subsoil profile.
  • Great N scavenger and easy management with winterkill at 22° F.
  • Quick growth and emergence that will outcompete weeds. Mixes well with legumes and/or radishes.

SEEDING AND MANAGEMENT:

  • Plant 6 weeks prior to average first frost. Winterkills at 22° F.
  • Seed at 32 to 64 lbs/A at ½” to 1” depth. Drilled or broadcast.

Triticale - Forerunner

  • Bred as a cross of Wheat and Cereal Rye with similar characteristics, but superior forage quality.
  • Excellent winter hardiness and rapid spring growth more that rye, can be winter grazed.

SEEDING AND MANAGEMENT:

  • Plant from late August up to mid-November. Emergence will take more time in cooler soil temperatures.
  • Available in bags or mini-bulks. Similar seed size as wheat.
  • Seed at 100 lbs/A at ½” to 1 ½”depth.

VNS Wheat

  • Inexpensive and most economical option of cereal grain cover crops. Cleaned and germ tested.
  • More shallow roots compared to Cereal Rye.
  • Very easy to terminate in the spring.

Ebberts Nutribuilder Mix

  • 3-way mix of 47% Winterhawk Annual Ryegrass, 39% Crimson Clover, and 14% Daikon Radish.
  • Provides deep soil tillage, soil building, and N-fixation in one mix.
  • Increases organic matter, loosens compaction, and improves water holding capacity and infiltration.
  • Great for improving earthworm populations.

SEEDING AND MANAGEMENT:

  • Plant 6 weeks before first average frost.
  • Seed at 20 lbs/A at ½” to ¾” depth. Can be drilled or broadcast.
  • Crimson clover usually overwinters, radishes winterkill, and annual ryegrass will need to be terminated in the spring.

*See Winterhawk Annual Ryegrass for burndown recommendations.

Ebberts Groundbreaker Mix

  • 2-way mix of 86% Austrian winter peas and 14% Daikon Radish.
  • Reduces soil compaction, produces nitrogen, and scavenges nutrients in one mix.
  • Excellent in wheat stubble going to corn, expect full winterkill if planted in August after wheat.
  • Also used after early soybeans going to corn. Winterkill will depend on fall growth of the peas and snow cover in the winter.
  • Huge biomass builder with low C:N ratio that decomposes fast in the spring.

SEEDING AND MANAGEMENT:

  • Plant 6 weeks before first average frost.
  • Seed at 30 lbs/A at ¾” to 1” depth. Works best when drilled.
  • Seed size is 3000 to 3500 seeds per lb. Use Winter Pea inoculant for best results

*** About Dormant Seed ***

Certain species of seeds that are utilized for cover crops have shown a portion of dormant seed present. “Dormant” seed contains properties that inhibit germination right away. Over time under a particular set of conditions, the dormancy will break thus allowing the seed to germinate. This is nature’s way of making sure the species continues. For example, if some phenomenon wiped out every radish on earth, next year there would be approximately 4% of radishes that would emerge as that is the normal level of dormancy for that species. We are working to learn the normal dormancies for cover crops, but it is very inconsistent because it depends on seed production growing conditions and the age of the seed. The point is to be aware that this can happen and it is normally not a production detriment.
