Early harvest cover crops
Thinking about planting cover crops after wheat? Cover crops after wheat provide many benefits, such as preventing erosion, improving soil health and productivity and suppressing weeds.
How to get started with cover crops after winter wheat:
1. Bale off straw or ensure straw and chaff are evenly spread
2. Removing weeds and volunteer wheat allows the cover crop to get a good start
3. Consider your wheat herbicide program when selecting a cover crop
4. Plant as soon as possible after wheat harvest
5. Drill, broadcast or incorporate cover crop seed to get faster results
Cover crop seeding rate chart
Early harvested crops like wheat offer a significant growing period for cover crops. Keep it simple with oats or build diversity with seed mixtures. Adjust seeding rates based on intended use (e.g. higher rates for feed purposes). Available options include (but not limited to):
| Cover Crop |
Seeding Rate |
Goal |
Control |
Comments |
| Oats (or barley) |
20 to 50 kg/ha ********************* 80 to 100 (100-125) kg/ha |
Cover, soil building ********************* Feed |
Winterkills, tillage,
|
Broadcast or drill |
| Oats and peas |
30 to 50 kg/ha ********************* 80 to 100 kg/ha oats and 50 to 75 kg/ha peas |
Cover, soil building ********************* Feed |
Winterkills, tillage, herbicide |
Drill - peas need soil contact |
| Oats and radish |
25 to 40 kg/ha |
Cover, soil building |
Winterkills, tillage, herbicide |
Keep radish rates at 1-3 kg/ha or less |
| Winter cereals (e.g. rye, wheat, triticale) |
40 to 60 kg/ha ********************* 60 to 120 kg/ha |
Cover, soil building ********************* Feed |
Tillage, herbicide |

Multi mix - 3 or more legume, broadleaf) |
25 to 50 kg/ha + depending on species |

May support pollinators if flowering |
