This can be an inexpensive mulch if chips are <br />obtained from trees cleared on the site. <br />%DUNFKLSVDQGVKUHGGHGEDUN are by-products of timber processing often <br />used in landscape plantings. Bark is also a suitable mulch for areas planted <br />to grasses and not closely mowed. It may be applied by hand or with a mulch <br />blower. Unlike wood chips, the use of bark does not require additional <br />nitrogen fertilizer. <br />:RRG¿EHU refers to short cellulose fibers applied as a slurry in hydroseeding <br />operations. Wood fiber does not require tacking, although tacking agents <br />or soil binders can easily be added to the slurry. Wood fiber hydroseeder <br />slurries may be used to tack straw mulch on steep slopes, critical areas, and <br />where harsh climatic conditions exist. :RRG¿EHUPXOFKGRHVQRWSURYLGH <br />VXI¿FLHQWHURVLRQSURWHFWLRQWREHXVHGDORQH. <br />There are other organic materials that make excellent mulches, but may only be <br />available locally or seasonally, for example: dried sewage sludge, corn stalks, <br />animal manure, pine boughs, cotton burs, peanut hulls, and hay. Creative use <br />of these materials can reduce costs. <br />&+(0,&$/08/&+(6$1'62,/%,1'(56 <br />A wide range of synthetic mulching compounds is available to stabilize and <br />protect the soil surface. These include emulsions or dispersions of vinyl <br />compounds, asphalt, or rubber mixed with water. They may be used alone, or <br />may be used to tack wood fiber hydromulches. <br />When used alone, chemical mulches do not insulate the soil or retain moisture, <br />and therefore do little to aid seedling establishment. They are easily damaged <br />by traffic, are usually more expensive than organic mulches, and they <br />decompose in 60-90 days. <br />&KHFN ODEHOV RQ FKHPLFDO PXOFKHV DQG ELQGHUV IRU HQYLURQPHQWDO <br />FRQFHUQV7DNHSUHFDXWLRQVWRDYRLGGDPDJHWR¿VKZLOGOLIHDQGZDWHU <br />resources. <br />1(760$76$1'529,1* <br />Netting is very effective in holding mulch in place on waterways and slopes <br />before grasses become established. <br />Mats promote seedling growth in the same way as organic mulches. They are <br />very useful in establishing grass in channels and waterways. A wide variety <br />of synthetic and organic materials are available. “Excelsior” is a wood fiber <br />mat, and should not be confused with wood fiber slurry. <br />When installing nets and mats, it is critical to obtain a firm, continuous contact <br />between the material and the soil. Without such contact, the material is useless, <br />and erosion will occur underneath. <br />)LEHUJODVVURYLQJ consists of continuous strands of fiberglass which, when <br />blown onto the soil surface from a special compressed air ejector, form a mat <br />of glass fibers. This mat must then be tacked down with asphalt. <br />DocuSign Envelope ID: AEB4824B-973E-408D-9C1C-5EDDD8B50786
