Nitrogen fertilizer at <br />the rate of 30-40 pounds of available nitrogen will be broad- <br />cast on the surface just prior to seeding or following covering <br />of the seed. An additional application of nitrogen fertilizer <br />at the same rate will be beneficial when grasses reach a height <br />of from 2 to 3 inches. <br />before or at the time of seeding.

The mulch must be partially incorporated into the <br />soil using a shovel after seeding. <br />Weed Control <br />Annual weeds and grasses frequently present severe compe- <br />tition with planted grass seedlings and cause high mortality <br />that may result in seeding failures. Seeding success in this <br />area will be enhanced by control of weedy competition during <br />both the first and second growing seasons. <br />Since the prime time for seeding this mining site falls <br />i.n mid-summer, it will be necessary to have a weed control <br />program during seedling establishment. The post-emergence <br />herbicide 2, 4-D may be applied at a rate of 1.5 pounds of <br />acid equivalent per acre to perennial grass seedlings without <br />causing damage to them. <br />E-5 <br />1 <br />
