Cover crop: After the topsoil has been spread over the areas to be reclaimed, it should be <br /> seeded to a cover crop. The recommendation is to use a sterile or hybrid forage sorghum. This <br /> should be seeded at 3-5 pounds per acre. A warm season sterile sudan may used at a 5-10 <br /> pounds per acre seeding rate. Seeding around mid June to mid July has resulted in the best cover <br /> crops. A crop height of two to three feet is adequate. Do not mow the cover crop as this will <br /> make drilling very difficult. Tall cover can be drilled through if it is attached to the soil. <br /> 4. Fertilizer: Fertilizer should not be needed if the top soil is re-distributed evenly over the area. <br /> 5. Grass seeding: Grass seeding should be done between November 1 and April 30. Seeding <br /> should not be done when the ground is frozen. The seedbed should be firm, moist, and clean of <br /> weeds. Seeding should be in a cover crop of clean, weed free sorghum or sudan. <br /> The following is a recommended seeding mix: (also attached). <br /> Grasses %in mix Seed rate—PLS /lb/ac <br /> Western wheat - Arriba, Barton 15 3.2 <br /> Switchgrass - NE 28, Blackwell 30 1.0 <br /> Big bluestem - Bison, Kaw, Champ 10 1.10 <br /> Yellow Indian— Cheyenne, Holt 15 1.5 <br /> Blue grama- Alma, Hachita 10 0.3 <br /> Sideoats grama—El Reno,Niner, Vaugh 10 0.9 <br /> Alfalfa - Ladak, Ranger 10 0.8 <br /> Seeding rates are in Pure Live Seed (PLS). PLS is % of purity X% germination. A grass drill <br /> must be used with depth bands,packer wheels, and seed agitator. The seed should be placed '/ <br /> to %2 inch deep. <br /> 6. Mulching: A cover crop will be used in place of mulching. If the cover crop fails or <br /> mulching is needed, 4000 pounds per acre of good, clean straw or native grass hay should be <br /> used. The straw or hay should be crimped into the soil. <br /> 7. Weed control: Weeds can be controlled by mowing. Mow only if there is a risk of weeds <br /> breaking loose and rolling or tumbling that would cause problems in fences, tree rows , <br /> homesteads, etc. These would include Russian thistles and kochia. Mowing should be done <br /> before the plants go to seed. The mowing height should be eight to twelve inches to minimize <br /> the scalding/scorching of grass seedlings. Mowing should not be necessary after the second <br /> year. Chemical weed control should be avoided due to both grasses and broadleaf plants in the <br /> mix. <br /> If you need additional information, please call our office. <br />
