43 <br />rI Treatment 6: 220 kg P205/ha, 66 kg Kz0/ha, 132 kg N/ha + excelsior mulch • <br />i <br />Treatment 7: 220 kg Pz05/ha, 66 kg KZO/ha, 66 kg N/ha + straw mulch <br />Treatment 8: 220 kg P20;/ha, 66 kg KZO/ha, 132 kg N/ha + straw mulch <br />1 <br />Seeding took place in November of 1916 with a mixture of native and <br />introduced grasses, fortis, and shrubs (Table 10). Subplots were treated with <br />appropriate levels of fertilizer which were subsequently rototilled into the <br />spoils (Figure 9). Seeding followed by a broadcasting method at a rate of <br />12.8 kg pure live seed (PLS)/ha (634 PLS/mz) and raked to lightly cover with <br />soil. Finally, excelsior or straw mulch was added to designated treatments. <br />I <br />Slope Plot <br />The Slope Plots were constructed en a southeast-facing slope. One <br />plot is graded on a 3:1 slope and the second to 1.5:1. Treatments used, and . <br />their arrangement, appear in Figure 9. Three treatments, measuring 7.5x6.0 m, <br />were installed in two replications. All treatments were fertilized with <br />220 kg P,OS/ha and b6 kg N/ha and broadcast seeded at a rate of 43 kg pure <br />I <br />live seed (PLS)/ha (1450 PLS/m--). The fertilizer and seed were raked into the <br />soil and mulch, as either straw (2240 kg/ha) or excelsior matting, was applied. <br />Species used on the Slope Plot are listed in Table 11. The treatments <br />examined are outlined below. <br />Treatment l: 220 kg PZO;/ha, 66 kg N/ha, + excelsior mulch <br />Treatment 2: 220 kg PROS/ha, 66 kg N/ha, + straw mulch <br />Treatment 3: 220 kg P 0 /ha, 66 kg N/ha, + straw mulch + topsoil (to a <br />depth of 15 cm) <br />'~ <br />
