Influence of mine spoil type, fertilizer, and mycorrhizae on pines seeded in greenhouse trays
Growth and mycorrhizal colonization of surface-seeded pine (Pinus sp.) as affected by two different mine spoil types (siltstone and sandstone), two fertilizer treatments (control and 100 kg/ha each of N, P, and K), and three mycorrhizal inoculation treatments (control, 56 kg/ha pine litter, and 250 g/ha Pisolithus tinctorius (Pers.) Coker and Couch (PT) basidioxpores) were evaluated in a greenhouse experiment. Emergence was highest (12, 55, and 34% for P. strobus, P. virginiana, and P. taeda, respectively) in nonfertilized siltstone, but growth performance was greatest in fertilized sandstone. Fertilization increased shoot weight of white, Virginia, and loblolly pine growing in sandstone spoil two-, ten-, and eightfold, respectively. Fertilization had no effect on seedlings growing in siltstone spoil. Mycorrhizal inoculation of Virginia pine was effective in sandstone but not in siltstone spoil. Addition of pine litter and Pisolithus tinctorius spores to sandstone spoil increased the percentage of colonized Virginia pines by 27 and 33%, respectively. Inoculation had no effect on the number of white and loblolly trees colonized.
