~' EEVEGETATION PLAN Aa stated before, elopes should be kept as gentle as possible to aid in the establishment of vegetation. Additional topsoil may or may not be necessary depending upon the material available at the site. If topsoil is stockpiled for an ex- tended period of ties, temporary vegetation should be established to prevent erosion and maintain soil microbial populations. fertilizer requirements - The rate of fertilizer application should be no less than SO pounds of nitrogen (N) and 50 pounds of phosphate (PZOS5) per acre. Animal manures or similar organic material may be used to supply all or part of the specified nutrients as well ae doubling ae a mulch. Time of application should be immediately prior to seeding, at the time of seeding, or is®ediately following seeding, as applicable to the kind of fertilizer and type of equipment used, Seedbed preparation - The seedbed should be well settled and firm, but friable enough that seed can be placed at the seeding depths specified. The seedbed should be reasonably free of weeds. Competitive stands of weeds that are present before seeding moat be controlled by shallow tillflge or by application of herbicides labeled for this purpose. Soils that have been over-compacted by traffic or equipment, especially when wet, should be tilled to break up rooting restric- tive layers, and then harrowed, rolled or packed to prepare the required firm seedbed. Method and depth of seeding - Seed should be planted with a drill on all slopes of 39 percent (3:1) or flatter. The drill meet have the capability of handling the kind and rate of seed being planted. Seed planted with a drill should be covered with soil to a depth of 1/4 to 3/4 inch. Seed may be broadcast by hand or mechanical spreader on areas too steep or not accessible for seed-drill operations, Seed planted by the broadcast method should be incorporated into the surface soil, not to exceed a depth of 3/4 Inch, by raking, harrowing or other proven method,
