Work on the possible use of palm oil mill effluent for improvement of land degraded through erosion by water and tin mining operations is reviewed. The available information shows that palm oil mill effluent (POME) treatment improves the water availability, carbon and nitrogen content and microbial activities in tin tailings. It is also a useful source of plant nutrients and water for crops grown on normal or degraded land. Greenhouse studies indicate that palm oil mill effluent is inferior to sewage sludge but generally superior to rubber effluent in improving soil conditions for growth. POME was also shown, in the laboratory, to have a greater effect in stimulating microbial activities than rubber effluent. The potential for POME as a fertilizer has been demonstrated on millet (Eleusine esracana Gaertn) and okra (Hibiscus esculentus) on sandy tailings. Significant increase in growth or both crops from treatments with settleable solids and not from those with raw or treated effluents was observed
