Summary : The sub-marginal condition and the cost of rehabilitation deter most of the mine spoil rehabilitation efforts. As an alternative, bioremediation has been resorted to. This study evaluated the potentials of mycorrhiza, fertilizers and the use of tolerant species in the bioremediation of a mine waste dump of Antamok, Itogon, Benguet. Seedlings of Casuarina equisetifolia Forst., Alnus maritima Marsh Nutt. and Eucalyptus camaldulensis Dehn. were raised in the nursery and subjected to mycorrhizal inoculation treatments. These seedlings were planted in the mine spoil and were further subjected to four fertilizer treatments: 120g compost, 0g NPK, 5 g NPK and 20g NPK. Two months after treatment application, height and diameter increments were measured every month. Other parameters measured include survival, biomass, N, P, K, Cd, Cr, Mn, and Fe uptake eight months after field planting. Results showed that, except for Alnus, seedlings planted in mine spoil responded positively to mycorrhiza. Likewise, Agoho and eucalyptus responded positively to application of 20g NPK. Both nutrient uptake and heavy metal uptake indicate the positive role of mycorrhiza and fertilizers in increasing plant tolerance to nutritional imbalance and heavy metal toxicity.
