I <br /> 1 . After earth disturb.tnce operations the followLn� steps ar needed : <br /> �I A Sidi- slopes should he flatter than l :l .

E>;ress water from adjacent areas should not be a1lowe to <br /> Clow onto the -irra unlv,s erosion concroL prnctices a e <br /> imp Lcineated. <br /> C. Length of slope should be properly controlled to prove t <br /> erasion. <br /> D. Topsoil is needed uu sites having exposed soil surface <br /> low in organic material and texture classification of <br /> clay Loam or heavier. This need increases significant y <br /> if the soils arc inherently dry, if the slopes are <br /> greater than 6:1 and if the slope aspect is south or <br /> southwest. Topsoil should be applied after shaping an tilled <br /> to a depth of 6 inches binding topsoil to existing soi <br /> 2 . Fertilization <br /> A . Fertilizer of not Less than 40 lbs . nitrogen and 40 lbs . <br /> phosphorous should be applied unless a soil analysis i icates <br /> sufficient amounts of these elements. Application of <br /> fertilizers should be immediately prior to or at the ti e <br /> of seeding. <br /> J . Seedbed Prcvaration <br /> :\ . The seedbed should be prepared immediately following al <br /> earth moving operations prescribed in the engineering a d <br /> landscape design. <br /> 3. All rocks, trash and other de-ris that will interfere w th <br /> seeding should be removed . T_11 the ground to a depth f <br /> 4 to 6 inches . If the seedbed is prepared immediately <br /> following construction this operaC2 on can usually be am tted , <br /> except on fresh cut areas that have not otherwise Seen <br /> disturbed , Apply fertilizer, seed and mulch , if needed. <br /> Mulch ing <br /> A . A mulch may be needed to conserve mo; scure , prevent <br /> crusting , reduce runoff and erosion and help establish <br /> a plant cover. <br /> 3. Mulching material should be applied immediately before o <br /> after seeding. <br /> C. Either one of the mulching methods 1`_sted below would be <br /> acceptable. <br /> 1. Grass hay or cereaL grain straw should be used at <br /> an application rate of 4,000 lbs . lac, of air dry mat rial. <br /> At least 30": of die mulch by weight sha11 be 10 inch s <br /> or more in length . Anchor mulch immediately after <br /> distributing wick mulelt crimper or disc plow. <br />
