Grass Establishment Notes for Ranchers

Below is a list of questions and answers I have compiled from specialists on seeding techniques for grasses. For further information about forage establishment, please contact the Chouteau County Extension at 622-3751 or stop in for a visit. We are located in the green building next to the Courthouse.

Should I include a nurse crop in with the seed mix? “I usually don’t like to put a nurse crop in. I think it is too much competition when the plants are trying to get going, and we have seen it have a negative impact on field performance years into the stand life. If the producer is doing it because he has weed issues, I would try to clean up the weeds first before seeding the grass species” (Emily Glunk, 2016).

When should I seed grass? “There are three opportunities for seeding grasses in much of central Montana. March through early June, Late July to early mid -August (dependent on moisture near the surface), and dormant seeding in November” (Dave Wichman, 2014).

What is the seeding rate for grasses? “Thirty seeds per foot of row is the optimum seeding rate for many grass species. The pounds of seed per acre ranges from 3 to 7 pounds per acre, depending on the species seed size and density” (Dave Wichman, 2014).

At what depth should I seed forage seeds? Forage seeds should be planted into a firm seedbed and at a depth of less than one-half inch. This is best accomplished with a drill that has depth bands, a seed agitator and packer wheels (Dryland Pastures in Montana and Wyoming, 2003).

What is the best blend for seeding grass pasture? “Mixing of grasses species for pasture is not an encouraged practice because the grazing animal will prefer one grass species over the other” (Dave Wichman, 2014).

What varieties would you recommend for dryland hay production in a 12-14 inch rainfall? “Intermediate/pubescent wheatgrasses are the most productive for Central

See Page 3: Green Ag Research Center. Both varieties are long lived when sufficient soil nutrients are available and not stressed with repeated close grazing” (Dave Wichman, 2014).

When should I fertilize? “There is usually not a forage production advantage for fall applied fertilizer over early spring applications. Fall applied Nitrogen can provide an advantage for grass seed production” (Dave Wichman, 2014).
