A drill rate is given as it is the starting basis for the broadcast method of application but the seed will be broadcast.. Seed Application Method (iv) Seed will be broadcast and pressed into the soil with the available equipment. For example: if a dozer is on site, the dozer can "walk" the seeded area, pressing the seed into the soil. Other methods can be a light drag, a roller, an ATV, or similar equipment. Seed to soil contact and a firm seed bed enhance germination of most species. A note of caution: seed should not be pressed too deeply into the soil. Most grass seed requires a depth of 0.25-0.5 inches for proper germination and deeper placement reduces success. Forage kochia should not be pressed into the soil. Hence, after all other seeding and pressing of the seed into the soil is done, the forage kochia is to be broadcast. Timing is critical with forage kochia, with late fall to late winter being the best period (late November- late February). It is acceptable to broadcast on upwards of 6 inches of snow or frozen ground. Forage kochia is normally harvested in late November and after the first hard frost; the fresh seed generally has the highest success in establishing a stand of forage kochia. Old or improperly stored forage kochia seed can have a very poor germination rate, at times well under 50 percent. The timing of the seeding is important, with a late fall to very early spring seeding having the best germination and survival for most grass species in the mix, considering the pits geographical location and climate. Timing of seeding is limited due to the requirements forage kochia. D8
