The most desirable seed bed will be one where the surface will be left in a Senn-roughened condition so that the seed can work its way into surflcial cracks and small openings. If necessary, to improve the coverage of the seed by soil materials and to improve soil contact, areas may be dragged by chains, takes or similar implements to aid in seed coverage. Some hand-raking may also be necessary to cover seed with soIl materials. 2.4 MULCHING If necessary to control erosion and conserve soil moisture, mulching of reclaimed areas will be employed after seeding is completed. Mulch may consist of the use of clean straw ox hay mulch, hydromulching, ox erosion control blankets, etc. A tackifiex may also be applied at the rates recommended by the manufacturer to aid in retention of mulch materials on steeper slopes. 2.5 PLANTING TIME The seed mix is comprised primarily of cool season species. Fall planting will primarily be employed to allow these species to bene£t from cold winter temperatures and moisture for spring germination requirements. Early spring seeding may also be employed if soil moisture and temperature conditions axe conducive to seedling establishment. 2.6 IRRIGATION AND FERTILIZATION Use of the planting and mulching methods specified above will result in satisfactory plant establishment, barring abnormally dry conditions. There are no plans to irrigate the reclaimed areas. MR-83 H-4 Rev. August 2006
