7 Wctbod St BofTcr Sccdiaf Plaa <br />The following seeing plan utilizes elements and recommendations from the Seeding Manual of <br />MnDOT Office of Environmental Services, Turf Establishmera and Erosion Control Unit, Draft <br />Year 2000. <br />EismituQjttd.Sfifidio8 <br />1. The smooth-graded wetland and bufo areas designated for seeding should be prepared <br />by loosening topsoil to a minimum depth of 3 inches. The designated upland bufier areas <br />• that ha^ not been graded and contain existing vegetation should be prepared by mowing <br />at a height of 4-6 inches in late April/early May or late August/eariy September. The <br />grass should be aUowed to rc-grow before herbickle application (1-3 weeks). <br />Recommended herbicide rates are 2 quarts/acre of glyphosate and 1-2 quarts/acre of 2,4- <br />D. The soil can then be loosened and seeded 7-10 days after herbicide treatment <br />2. Seeding should be conducted either April 15-July 20 or Sept. 20-October 20. Seeding <br />can be acconq)ltshed by broadcast or drilling. Broadcast seeding is particularly <br />recommended for the wetland seed mixture unless the weather is hot and dry and/or the <br />soil moisture content b low at the time of seeding. Broadcast seeding should by <br />accomplished by u» of any type of broadcast seeder capable of broadcasting the seed <br />evenly over the entire area. Seed should be mixed thoroughly prior to seeding and should <br />be mixed occasionally in the spreader to prevent separation and settling. If the drill <br />seeding method b used, seed should be installed with a Truax-type seed drJl containing a <br />minimum of 2 seed boxes (6ne seed box & box for largc/flufi^ seeds) and equipped with <br />dbc furrow openers and packer assembly to compact the soil directly over the drill rows. <br />Maximum row spacing should be 8 inches. Small and fine seeds should be drop-seeded <br />onto the surfitte from the fine seed box, and large/fluflfy seed should be placed to obtain a <br />final planting depth of Vi-'/i inches. All drill seeding should be done at a right angle to <br />surfoce drainage. Recommended seeding rates are given for the bufifer and wetland seed <br />mixtures at the end of thb plan. <br />3. The seeded areas shoi^ be harrowed or raked following seeding. The areas should then <br />be pack^ using a cuh^ker or equivaleut. Packing will be considered adequate when <br />only a slight footprint b left in the soil after walldog across the area. <br />4. Following packing, the areas should be mukhed and disc-anchored at a rate of 2 <br />tons/acie using MCIA certified weed free mulch. MnDOT Type 7 or 8 prairie hay/mulch. <br />or MnDOT Type 1 clean straw mulch. <br />Mmlenange and Evahiation of Seedir^y <br />Year 1 (spriqg seeding) <br />Prepare and seed site April 15-July 20 <br />Mow to a height of 6-10 inches Ju|y 20-August 20 <br />Optioaal mowing mear|y September <br />Spot sprqr weetfy q>ecies such as thbtles <br />S.
