Simple to grow cover that is commonly used in a mix with other species, Less winter hardy than cereal rye or wheat, Mix with cereal rye for increased weed suppression and increased winter survival of hairy vetch, Slow-growing cover crop so seed early for best growth, Terminate before seed production to avoid hard seed, Produces large amounts of below ground biomass with less above ground growth than cereal rye, Adding oats to the mix could help protect the ryegrass and help it to overwinter, Can be difficult to terminate in the spring so timely and proper herbicide applications are needed, Thrives in shaded conditions, so good option for interseeding, Avoid Italian ryegrass- generally used for forages and are mixed varieties, Most-likely will winter kill but is not controlled with glyphosate if it doesn’t, Winter annual that also attracts pollinators and beneficial insects, Does well mixed with cereal rye or other cover crops, Shortest growing type of clover that tolerates traffic and compaction, Does well interseeded, frost seeded, or in a cover crop mix, Quick-establishing cover for spring or fall, Mix well with other covers as a nurse crop, Soil health benefits: scavenger for nutrients, suppress weeds, breaks up compaction, Not as vigorous in growth as radish, but superior option for grazing, but should not comprise more than 35% of the livestock diet, Best results when planted in a mix late summer/early fall, After freeze rotting radishes create a strong odor so be cautious in residential areas, Extremely fast-growing, good source of forages, Caution grazing during and after a frost and before plants are 18-36” due to potential for prussic acid poisoning and nitrate toxicity with the right conditions.

Choose tough, low-growing covers such as grasses or clovers. Many require temperatures in the lower twenties to high teens for termination. Also consider ways to extend or overlap cropping windows. Another option: Band a cover or some insect attracting shrubs around fields or along hedgerows to suppress weeds or provide beneficial habitat where you can’t grow cash crops. Too much N might stimulate excessive tree leaf growth or prevent hardening off before winter. Best Nitrogen Preservation Cover Crops: Hard Winter Wheat, Triticale, Annual Rye, Barley, Tillage or Daikon Radish, Oats. Properly managed, living mulches give many growers year-round erosion protection, weed control, nutrient cycling and even some nitrogen if they include a legume. Broadleaf cover crops are non-grass, non-legume species such as buckwheat. If ground cover and N recycling needs are minimal, rye can be planted as late as the frost period for successful overwintering. Oats planted two weeks after corn harvested for silage yielded 2,800 pounds of DM per acre. Part of it is because of weather and timing.

Mixed winter-hardy & winter-killed cover crops Many growers use a mixture of cover crops from the two categories. Farmers need to consider a few factors: soil fertility and condition, yield, and nutritional value to sheep. In a moderate rainfall region after small grain harvest in late summer, you want a soil-protecting winter cover that can supply N for no-till corn next spring. With that early establishment, these covers are more likely to survive the cold temperatures and continue growing in the spring.
