The Swath Grazing Blend
The Swath Grazing Blend
Waxy leaf surfaces (an evolutionary trait) of warm season plants have changed the swath grazing landscape. A blend including C4 plants such as Sorghum Sudan & German Millet allows the swath to shed moisture (rainfall) and hold palatability longer.

C4 plants make this blend ideal for shedding moisture (rainfall) & avoiding spoilage when placed in a swath.

See below for the most frequently asked questions regarding the Swath Grazing Cover.
If applying Nitrogen, keep below 40 Ibs/actual.
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.
Due to the waxy leaf surfaces of the warm season plant species (limited evapotranspiration) this makes the blend ideal in a swath for shedding moisture (rainfall) & avoiding spoilage.
German Millet: Waxy Leaf
Sorghum Sudan: Waxy Leaf
The Swath Grazing Cover will reach full biomass potential about 50-60 days after germination.
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.
There are two main advantages of incorporating warm-season plants into the blend:
Reduce evapotranspiration from within the leaf.
The waxy leaf surfaces are ideal in a swath for shedding moisture (rainfall) & avoiding spoilage.

Depending on soil temperature, soil chemistry, and environmental conditions present, a different spectrum of plant species in the canopy is always expressed.
This is why plant diversity is an insurance policy with Mother Nature.
STEP 1: If weed pressure is an issue or you have a history of problem weeds on the field you selected, we recommend a pre-burn herbicide application (with no residual). Do not plant on fields with kochia problems.
STEP 2: If applying Nitrogen, keep below 40 Ibs/actual. A multi-species rhizobium inoculant is required. Excess nitrogen fertilizer will inhibit legumes in establishing a relationship with rhizobium bacteria. ‘
STEP 3: Do not broadcast. Target 3 ⁄4 of an inch or up to 1 inch if moisture is available. The larger seeds will “give way” to the smaller seeds in the blend. Do not bury the blend 2-3 inches into the ground.
STEP 4: Waiting for ideal soil temperatures (10 degrees C) allows the warm season species to establish & avoid frost risk - increasing the potential for yield, feed quality & drought resilience.
One of our most popular Farm Panel Discussions! Listen to three panelists from across Western Canada discuss their experiences with swath grazing.
Hear from Owen Taylor, who served as the Territory Manager for Manitoba and is also a farmer. Discover valuable insights he has gained during his experience with swath grazing.
See below for some general information regarding each plant species in the blend.
Warm Season Grass
Mycorrhizal dependent: Yes
Water Use: Low
Comments: The most valuable plant species in the blend. Sorghum Sudan is C4 grass, which allows for rapid biomass production in hot summer conditions. Sorghum Sudan has the ability to capture sunlight atop the canopy. Reduced lignin content and higher forage digestibility than corn makes it ideal for winter feed.
Warm Season Grass
Mycorrhizal dependent: Yes
Water Use: Low
Comments: Longer growing season than most millets. Extremely vegetative. Waxy leaf surface ideal for winter forage. C4 grass.
Warm Season Broadleaf
Mycorrhizal dependent: No
Water Use: Low
Comments: Due to its non-mycorrhizal association, root exudates are very good at solubilizing phosphorus. Beneficial to pollinators. Rapid establishment.
Warm Season Broadleaf
Mycorrhizal dependent: Yes
Water Use: Low
Comments: Flowers attract a large array of beneficial insects. Beneficial at solubilizing minerals in soil profile. (zinc)
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 Broadleaf (Linum)
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Highest mycorrhizal fungi-dependent plant. Having a small percentage in the blend helps promote the Arbuscular Mycorrhizal Fungi network.
Cool Season Legume
Mycorrhizal dependent: Yes
Water Use: Medium
Comments: Forage pea varieties focus on smaller seed size & increased biomass - rather than on grain yield. Rapid growth & establishment.
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.
Warm Season Legume
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Fenugreek is a fast-establishing annual warm-season legume that provides nitrogen fixation to the system when conditions are hot and dry.
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Low
Comments: We swapped Forage Barley (awns) for Soft White Wheat for the increased palatability.
Cool Season Grass
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: We introduced a longer season IRG for 2025. Highly digestible with vigorous regrowth. Less chance of over-winter, unlike annual ryegrass. A fibrous root system is excellent for compaction.
Plant Type: Cool Season Legume
Mycorrhizal Dependent: Yes
Water Use: Medium
Comments: Hairy Vetch holds the highest nitrogen fixation capabilities of any legume species we grow in Western Canada. Sunlight opportunist due to its creeping growth characteristics. High protein feed source. Regrowth.
