Seeding Mixture <br />The following seeding mixture recommended itt your letter <br />is appreciated. <br />Species <br />Pubescent <br />Western Wheatgrass <br />Side Oats Grama <br />Russian Wildrye <br />Pounds of pure <br />line seed/acre <br />9 <br />6.5 <br />4.5 <br />5 <br />Note: The local Soil Conservation Service <br />ly recommend Russian Wildrye. Blue <br />fair results in test plantings. As <br />least 10 years before any but small <br />plantings can be accomplished, impr <br />mixtures may be indicated later. <br />2. Soil Substitutes <br />does not current- <br />Grama has shown <br />i_t will be at <br />acreas and test <br />~ved seeding <br />Additional explanation of the brown and gra}~ spoil materials <br />as soil substitutes is indicated. Gray spoils oxidi~.e or air slack <br />in a few years to become brown spoils. A period of tame to allow <br />settling and oxidation is beneficial to plant growth. As stated <br />in the application, weathered shales near the surface: that can be <br />removed without blasting make the best soil substitute material <br />as partial oxidation has already occurred. <br />
