Abstract

A study was conducted to examine the combined biological and economic aspects of the use of mycorrhizal inoculation, hardwood bark mulch, and wood fiber mulch made from recycled paper in the establishment of loblolly pine (Pinus taeda L.) seedlings on surface mines. All mulches were applied in conjunction with clover, and one-half of each mulch treatment was fertilized. Over all treatments, mycorrhizal inoculation had no significant effect on survival and growth, although biological and economic benefits were observed in three specific instances. Unfertilized bark and clover was the most beneficial mulch treatment after nine growing seasons. Use of fertilizer with bark and clover should be avoided as a heavy ground cover is produced that is detrimental to tree seedlings. With wood fiber, however, applications of fertilizer enhanced tree performance as well as economic efficiency.
