P.EVEG TATION Gl1IDELIN`:S <br /> I. After earth disturbance operations the following steps are needed: <br /> A. Side slopes should be flatter than 1:1. Slopes of 6:1 or <br /> flatter are much more desirable for greater success in <br /> re-establishment of vegetation and operation of equipment. <br /> B. Excess water from adjacent areas should not be allowed to <br /> flow onto the area unless erosion control ornctices are <br /> implemented. <br /> C. Length of slope should be properly controlled to prevent <br /> erosion. <br /> D. Topsoil is needed on sites having exposed soil surfaces <br /> low in organic material and texture classification rf <br /> clay loan or heavier. This need increases significantly <br /> if the soils are 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 and tilled <br /> to a depth of 6 inches binding tonscil to existing soil. <br /> 2. Fertilization <br /> A. Fertilizer of not less than 40 lbs. nitrogen and 4,) lbs. <br /> phosphorous should be applied unless a soil analysis indi^nter <br /> sufficient amounts of these elements. Application of <br /> fertilizers should be immediately prior to or at the time <br /> of seeding. <br /> 3. Seedbed Preperation <br /> A. The seedbed should be prepared Prior to see(iina ; spe seecinr <br /> recommendations). If' the :irer is to be left b,,r(- 1'.)r 1on17sr <br /> than a few months, a temporary cover should be est,tbliche,.i. <br /> B. All rocks, trash and other debris that will. interfere .:ith <br /> seeding should be removed. Till the ground tc a denth of <br /> 4 to 6 inches. If the seedbed is prepared iT.cediatei;; <br /> following construction this operation can usually be ur.itted, <br /> except on fresh cut areas that have not otherwise been <br /> disturbed. Apply fertilizer, seed and mulch, if <br /> 4. Mulching <br /> A. A mulch may be needed to conserve moisture, prevent <br /> crusting, reduce runoff and erosion and help ectnblish <br /> a plant cover. <br /> B. Mulching material should be applied inredi,tcla <br /> after seeding. <br /> C. Either one of the mulching neth.,dr listed be Low v:ouid b <br /> acceptable. <br />
