This assumes that the cover is not disturbed or <br />mowed closer than 8 inches. <br />Hydraulic seeding may be substituted for drilling only where slopes are steeper <br />than 3:1 or where access limitations exist. When hydraulic seeding is used, <br />hydraulic mulching should be done as a separate operation to prevent the seeds <br />from being encapsulated in the mulch. <br />b See Table C4 for seeding dates. Irrigation, if consistently applied, may extend the <br />use of cool season species during the summer months. <br />c Seeding rates should be doubled if seed is broadcast; or increased by 50 percent <br />if done using a Brillion Drill or by hydraulic seeding. <br />Table C-3-Minimum Drill Seeding Rates for Perennial Grasses Alakali Soil Seed Mix <br />Common Name Botanical Growth Growth Form Seeds/ Pound Pounds of <br /> Name Seasonb PLS/acre <br />Alkali sacaton Sporobolus Cool Bunch 1,750,000 0.25 <br /> airoides <br />Basin wildrye Elymus cinereus Cool Bunch 165,000 2.5 <br />Sodar Agropyron Cool Sod 170,000 2.5 <br />Streambank riparium 'Sodar' <br />wheatgrass <br />Jose tall Agropyron Cool Bunch 79,000 7.0 <br />wheatgrass elongatum 'Jose' <br />Arriba western Agropyron Cool Sod 110,000 5.5 <br />wheatgrass smithii Arriba' <br />Total 17.75 <br />Fertile Loamy Soil Seed Mix <br />Ephriam crested Agropyron Cool Sod 175,000 2.0 <br />wheatgrass° cristatum <br /> 'Ephriam' <br />Dural hard Festuca ovina Cool Bunch 565,000 1.0 <br />fescue duriuscula' <br />
