The drill should <br />be equipped with a satisfactory seed-feeding mechanism, agitator, double disc openers with <br />depth bands and packer wheels or drag chains. Distances between drill rows should not exceed <br />12 inches. The best results are from a seed drill that has an 8 inch spacing between drill <br />rows. Seed may be broadcast if the site is not accessible to a grass drill. Broadcast rates <br />will be double the drill rates. The broadcast seed should be covered 1/2 to 3/4 of an inch <br />deep rake in. Care should be taken not to cover the seed over 3/4 of an inch since it will <br />probably not be able to germinate and emerge at deeper depths. If the soil is frozen seeding <br />should wait until the site can be drilled or broadcast and the seed covered to the required <br />depth. Hydro mulching might be a consideration on some sites that are difficult to reseed. I <br />would recommend that two operations be applied with hydro mulching. The seed applied first <br />and the mulch in the second operation. If the seeding operation is done all at once I would <br />ask the applicator for some assurances of success when applying the seed by hydro mulch. <br />The timing of the seeding should also be considered. Best results are with late fall seeding <br />before the ground freezes. Spring application will work but it may take longer to get a stand <br />of grass that holds the ground. Seeding should not occur from May 15th to the middle of <br />October unless supplemental water is available to germinate the newly seeded area. <br />Supplemental water could be applied at a rate sufficient to keep plants from stressing once <br />they are germinated. Apply about an inch of water per application during the first growing <br />season dependent on the amount of natural moisture received. <br />Upon completion of the seeding operation the site should be covered with weed free mulch at <br />the rate of 4,000 lbs to the acre and be crimped into the soil to prevent the straw from <br />being blown off the site. Mulches will provide a more humid environment for the seeding to <br />become established, help in providing wind erosion protection and conserve existing soil <br />moisture. I would recommend oat straw as a mulch.
