Nitrogen additions of both 50 and 100 pounds per acre increased the growth of loblolly pine (Pinus taeda L.) on surface mine spoil in East Tennessee; response duration appeared to increase when P was added. Liming appeared to decrease the response to N where trees were heavily mycorrhizal with Pisolithus tinctorious; while for non-mycorrhizal trees, the greatest growth was in plots receiving N with 2 tons of lime per acre. Applying a wetting agent and/or a NP fertilizer at planting time decreased survival but appeared to increase growth. Seedlings inoculated with mycorrhizal fungi survived better and grew more than those not inoculated. Grass competition reduced survival, however, rapid establishment of a complete grass cover has proved to be the most practical method for minimizing serious erosion in the first 6 months after grading. 7 references.
