. Irrigation. <br /> • Reapplication of mulch. <br /> . Repair of failed slope surfaces. <br /> This technique works with standard hydromulch (1 ,500 pounds per acre minimum) <br /> and BFM/MBFMs (3,000 pounds per acre minimum). <br /> . Seed may be installed by hand if: <br /> . Temporary and covered by straw, mulch, or topsoil. <br /> . Permanent in small areas (usually less than 1 acre) and covered with mulch, <br /> topsoil, or erosion blankets. <br /> . The seed mixes listed in the tables below include recommended mixes for <br /> both temporary and permanent seeding. <br /> . Apply these mixes, with the exception of the wetland mix, at a rate of 120 <br /> pounds per acre. This rate can be reduced if soil amendments or slow- <br /> release fertilizers are used. <br /> . Consult the local suppliers or the local conservation district for their recom- <br /> mendations because the appropriate mix depends on a variety of factors, <br /> including location, exposure, soil type, slope, and expected foot traffic. Altern- <br /> ative seed mixes approved by the local authority may be used. <br /> • Other mixes may be appropriate, depending on the soil type and hydrology of <br /> the area. <br /> .
