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