The objective is to loosen the soil u deep u possrble <br />(a minimum of eight inches), redudag duds and firming the sot3 to provide mmdmum <br />seed-to-sor7 conuct 7a addition to facilitation ofgermination of sends, tha sealbod should <br />provide conditions condudve to plant root devdopmeat. TiIIage should be paformed and <br />timed in a mattaer that mi®iza esoaiort, conae:vsa soil moisntte and takes advarttaYe of <br />the presence of plant residue if it eadsta. The final seedbed should be firm, fiiable and wad <br />Bra. <br />s>~DSE~ PxEPARArrox <br />Seedbed should be well >atled, 6rtn, and friable, to facilitate send plate at required <br />depths. The aces should be weed-froe (accomplished by nppiag prior to seeding). Should <br />tipping or dtiselirtg be regttind, it wt'Il be done on the rantour. Harfowing may lre <br />requitsd after ripping to a'eete a 5rm bed. <br />SEEDING <br />Sad should be plamed with a dn7I operated on the contour on all stapes of 33% (3:1) or <br />flatter. The drill must mat spxifications for the type of seed and se~erliog rates <br />reoomnunded. Seed may be broadcast by Gard, by mechanical spreader, ar by hydraulic <br />egtripmelft on areas that ate small, or too steep and/or inaccessible forsued-drz7ling. <br />Broadcast seed should be raked, harrowed or otherwise worked to provide arvesage by <br />soil. Rydtaulic application of seed and mulch in a sutgle operation is not accelrtable. <br />SEEDING RATES <br />Seeding rates included in the attaclud tables are for drill seeding. If seed is broadcast, <br />the rates mast be doubled. <br />SEEDWG DEPTH <br />Seed planted with a drill should be placed betweea'~ inch and'/. inch blow rite surface. <br />Broadcast seed should be incorporated into the surface soil by raking or ham~vring at <br />ATTAC[~'1' A <br />
