Well -cured feedlot/barnyard manure is recommended and may be used if readily available and will be applied at the rate of twenty tons per acre. (iv) Tree and shrubs planting: Deeply rooted species are not recommended in areas where slurry walls or earthen dams are constructed. None will be planted. (v) Topsoil replacement depth: Topsoil will be replaced to an average depth of 6 to 12 inches, some areas receiving more, some less. Only those areas of the interior slopes of the reclaimed water storage cells above the high water mark will receive topsoil, where riprap is not needed.
