3UDFWLFH6WDQGDUGVDQG6SHFL¿FDWLRQV <br />Rev. 12/93 6.14.5 <br />Apply asphalt at 0.10 gallons per square yard (10 gal/1,000 ft2). Heavier <br />applications cause straw to “perch” over rills. <br />In traffic areas, uncured asphalt can be picked up on shoes and cause damage <br />to rugs, clothing etc. Use types RS or CRS to minimize such problems. <br />Synthetic binders such as Petroset, Terratack, and Aerospray may be used, as <br />recommended by the manufacturer, to anchor mulch. These are expensive, <br />and therefore usually used in small areas or in residential areas where asphalt <br />may be a problem (Use of trade names does not constitute an endorsement). <br />Mulch nettings—Lightweight plastic, cotton, jute, wire, or paper nets may be <br />stapled over the mulch according to the manufacturer’s recommendations (see <br />“Nets and Mats” below). <br />3HJDQGWZLQH—Because it is labor-intensive, this method is feasible only in <br />small areas where other methods cannot be used. Drive 8-10 inch wooden <br />pegs to within 3 inches of the soil surface, every 4 feet in all directions. Stakes <br />may be driven before or after straw is spread. Secure mulch by stretching <br />twine between pegs in a criss-cross-within-a-square pattern. Turn twine two <br />or more times around each peg. Twine may be tightened over the mulch by <br />driving pegs further into the ground. <br />9HJHWDWLRQ—Rye (grain) may be used to anchor mulch in fall plantings, and <br />German millet in spring. Broadcast at 15 lb/acre before applying mulch. <br />&+(0,&$/08/&+(6 <br />Chemical mulches may be effective for soil stabilization if used between May <br />1 and June 15, or Sept. 15 and Oct. 15, provided that they are used on slopes no <br />steeper than 4:1, and that proper seedbed preparation has been accomplished, <br />including surface roughening where required. <br />Chemical mulches may be used to bind other mulches, or with wood fiber in a <br />hydroseeded slurry at any time. Follow the manufacturer’s recommendations <br />for application. <br />),%(5*/$66529,1* <br />Fiberglass roving (“roving”) is wound into a cylindrical package so that it can <br />be continuously withdrawn from the center using a compressed air ejector. <br />Roving expands into a mat of glass fibers as it contacts the soil surface. It is <br />often used over a straw mulch, but must still be tacked with asphalt. <br />Spread roving uniformly over the area at a rate of 0.25 to 0.35 lb/yd2. Anchor <br />with asphalt immediately after application, at a rate of 0.25 to 0.35 gal/yd2. <br />As a channel lining, and at other sites of concentrated flow, the roving mat <br />must be further anchored to prevent undermining. It may be secured with <br />stakes placed at intervals no greater than 10 feet along the drainageway, and <br />randomly throughout its width, but not more than 10 feet apart. As an option <br />to staking, the roving can be buried to a depth of 5 inches at the upgrade end <br />and at intervals of 50 feet along the length of the channel. <br />1(76$1'0$76 <br />Nets alone generally provide little moisture conservation benefits and only <br />DocuSign Envelope ID: AEB4824B-973E-408D-9C1C-5EDDD8B50786
