Growth and mycorhizal colonization of surface-seeded pine (Pinus spp.) as affected by two mine-spoil types (siltstone and sandstone), two fertilizer levels (control and 100 kg/ha each of N, P, and K), and three mycorrhizal inoculation treatments (control, 56 kg/ha pine litter, and 250g/ha Pisolithus tinctorius spores) were evaluated in a greenhouse experiment. The effects of four nurse crops and three fertilizer levels on ground cover, spoil erosion, and establishment of hydroseeded pines on a recontoured strip-mine in southwestern Virginia were also studied. In the greenhouse experiment, germination was highest (12, 55, and 34% for P. strobus, P. virginiana, and P. taeda, respectively) in non-fertilized siltstone, but survival was highest (85, 100, and 95% for the same species) in non-fertilized sandstone. Seedlings grown in fertilized sandstone had significantly higher stern and root biomass than those Mycorrhizal in any other inoculation spoil and treatments sandstone but not in siltstone spoil. In the field experiment, use fertilizer combination. were effective in of a nurse crop significantly increased ground cover over the controls, but the addition of a nurse crop or fertilizer resulted in a decrease in pine establishment of at least 46%. The only nurse crop to obtain the minimum 75% ground cover required by law was a Lolium perenne, Festuca rubra, and Lotus corniculatus mixture which, at 60 kg N/ha, reduced spoil erosion by about 70% over the controls while still allowing the establishment of 6,000 trees/ha. / M.S.

The effects of cultural treatments including ectomycorrhizal inoculation, chemical weed control, and slow-release fertilization on survival, growth, ectomycorrhizal colonization, and foliar nutrient levels of container-grown white (Pinus strobus L.), loblolly (P. taeda L.), and Virginia pine (P. virginiana Mill.) seedlings were studied on a recontoured and a fiat bench strip-mine site in Southwestern Virginia. One-half of the seedlings was inoculated with Pisolithus tinctorius (Pers.) Coker and Couch (Pt). A 21 g Agriform starter tablet was placed in the soil at a depth of 10 cm within 10-15 cm of each seedling in one-half of the plots at planting. Glyphosate was applied to one-half of each plot prior to planting and again later in the growing season. First year survival was not different between sites and was not significantly affected by the cultural treatments. Abundant precipitation and high soil moisture levels throughout the initial growing season may have accounted for the excellent first year survival. The combination of chemical weed control and fertilization significantly increased the growth of all three species. Pt inoculation enhanced seedling growth to some extent but high amounts of natural ectomycorrhizal colonization masked some of the effects of Pt. Levels of foliar nitrogen closely reflected the effects of each treatment on seedling growth, indicating that it was the growth-limiting nutrient for pine seedlings on these strip-mined sites. / Master of Science
