<br />The prescribed amount of water, mulch, and tackifying agent will be loaded into the mulch tank. <br />(Seetl will be applied in a separate operation.) These components will be mixed into a homogeneous <br />slurry in the tank. The slurry will remain agitated throughout the mulching process and be applied <br />uniformly over the seedbed to be treated. <br />3.17 Native Hay or Straw Mulch Netting <br />Netting will be used to anchor applied native hay or straw mulch on all areas too steep for, or <br />inaccessible to, agricultural machinery. Netting will be applied in the following manner immediately <br />following mulch application. <br />All rocks and debris which would inhibit the proper installation of netting will be removed from the <br />slope prior to mulching. The netting will be applied over the straw smoothly but loosely without stretching <br />from the top to the bottom of the slope. The top edge of the netting will be buried in a narrow trench 6 <br />inches deep with staples anchoring the netting within the trench. Where netting ends meet, the upslope <br />end will overlap the downslope end by 4 inches. Where lateral edges of rolls meet, an overlap from either <br />side of 4 inches will be made. Staples will be inserted on a 1-foot spacing along the top and bottom edge <br />of the netting. Staples will be inserted every 4 feet down each edge and the center to form an x-shaped <br />pattern. All staples will be inserted so that they are flush with the seedbed. <br />3.18 Native Hey or Strew Mulch Crimping <br />Disking can be used to anchor applied native hay or straw mulch to slopes accessible to equipment. <br />Disks used for this purpose will have dull and preferably notched, round-edged blades set straight. <br />Crimping should be completed by traversing the entire mulched area and anchoring the mulch, by rows, <br />approximately 3 to 4 inches into the seedbed on 8- to 12-inch centers. A mulch crimper is preferable and <br />should be used in lieu of a disk implement, if available. <br />3.19 Erosion Control Matting <br />Erosion control matting can be used to mulch steep slopes or as an erosion control backup for use in <br />emergency situations. Matting will be applied in a down-slope fashion except for small, linear-oriented <br />areas of cut- or fill-slopes. In such cases, the matting can be applied across the disturbed slopes. The <br />application procedure described below will be followed. <br />The surface will be treated to eliminate surface irregularities. Stones and rock fragments which <br />would inhibit mulch placement will be removed. The matting will be applied smoothly but loosely over the <br />surface without stretching. The upgrade end of the mat should be buried in a trench at least 6 inches <br />11 <br />
