The Seeding Early Blend
The Seeding Early Blend
An economical full season cover option without the insurance policy of warm-season plant species. The ideal blend to implement if you plan on seeding early.

See below for the most frequently asked questions regarding the Cool Season Cover.
Only a multi-species rhizobium inoculant (NDURE) is required. Excess nitrogen fertilizer will inhibit legumes in establishing a relationship with rhizobium bacteria. This relationship needs to be established for later season vegetation and growth.
With this being said, we do have growers applying 20-40 Ibs/actual N who have had positive results.
Due to only cool-season plant species in the blend, we do not need to worry about frost whereas for any blend with warm-season plant species - we need to wait until soil temperatures are between 6-10 degrees C.
This is the trade-off. Less drought tolerance and diversity but the cool season cover allows you to seed as early as possible to maximize biomass & regrowth potential.
There is no need for the drought resiliency of the warm season plant species if moisture is controlled.
Irrigation also means significant regrowth as moisture is always our limiting factor to regrowth on dry land acres.
The Cool Season Cover will reach full biomass potential about 60 days after germination. Due to plant diversity and indeterminate species, the window for silage is much wider than a monocrop forage.
Once the cool-season cereals start to turn - the silage/hay process should begin. Depending on your goals (re-growth for grazing, protein requirement, energy) you may choose to time your harvest differently.
Yes. Italian Rye Grass, Hairy Vetch & Berseem Clover will re-grow.
If you want more re-growth, cut early. If you want more winter forage with less grazing, cut later.
Yes. Decaying high-diversity root biomass will improve soil function greatly. (Increased water infiltration, soil aggregation & biological activity)
Remember to benchmark this by following our Water Infiltration Protocol.

By utilizing plant diversity, root exudates, and soil biology we are able to dramatically decrease input costs vs. a monoculture forage option. At the same time, a high-quality feedstuff is produced due to the balance of cereals (energy) & legumes (protein) in the blend.
The Cool Season Cover was also developed to utilize plant diversity, root exudates & soil biology to mimic the natural ruminant grazing system. Keep in mind, the productive soils we farm today weren’t built by monocultures, heavy tillage & synthetic fertilizer but by ruminant animals, mob grazing diverse grasslands.

Expect Italian Rye Grass, Hairy Vetch & Berseem Clover to re-grow - a balanced cattle feed (energy + protein).
*Moisture will determine regrowth
See below for some general information regarding each plant species in the blend.
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Great nutrient scavenger due to dense fibrous root system. One of the most mycorrhizal-dependent cereals.
Cool Season Legume
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Highest nitrogen fixation capabilities of legume species. Sunlight Opportunist. High protein feed source. Regrowth
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Highly digestible with vigorous regrowth. Will not over-winter, unlike annual ryegrass. Fibrous root system is great for compaction.
Cool Season Legume
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Forage pea varieties focus on smaller seed & increased biomass rather than grain yield. Rapid spring growth.
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Does well in a wide range of soil conditions including lighter soils or areas with moderate levels of salinity.
Cool Season Broadleaf (Brassica)
Mycorrhizal Dependent: No
Water Use: High
Comments: Highly nutritious brassica (digestibility & protein). Tuber scavenges nitrogen and other nutrients for slow release decomposition the following year.
Cool Season Broadleaf (Linum)
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: The highest mycorrhizal fungi-dependent plant. Having a small percentage in the blend helps promote the AMF network.
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Low
Comments: We swapped Forage Barley out for Soft White Wheat for 2025 for the increased palatability. (Awns from the barley)
Plant Type: Cool Season Brassica
Mycorrhizal Dependent: No
Water Use: High
Why In The Blend? Highly nutritious brassica (digestibility & protein) with rapid cool-season growth characteristics. Taproot for soil compaction and nutrient scavenging.
Remember to apply for the OFCAF funding to receive up to $35.00/acre (max. $75,000) for the adoption of multispecies cover crops on your operation. Click here for help getting the process/application started.
Funding will differ across Manitoba, Saskatchewan, & Alberta.
