Andisol is a soil that develops from volcanic ash material, dominated by amorphous aluminium silicate and Al-humus complex. This research was carried out at the Greenhouse and Laboratory of Soil Biology, Faculty of Agriculture, University of Sumatera Utara, Medan. This research used a randomized block design with 2 treatment factors and 3 replications. The first factor was Phosphate Solubilizing Microbial (PSM), namely: without application (M 0 ), 5 g of Mycorrhiza (M 1 ), 5 gr of Talaromyces pinophilus Fungi (M 2 ), 5 g of Burkholderia cepacia Bacteria (M 3 ). The second factor was organic matter, namely: without application (K 0 ), 180 g of cow dung (K 1 ), 180 g of chicken manure (K 2 ) and 180 g of OPEFB (Oil Palm Empty Fruit Bunch) compost (K 3 ). The research results showed that the administration of phosphate solubilizing microbes and several sources of organic matter could increase the soil pH by 0.61-29.12%, P-available by 1.46-112.64%, plant height by 5.41-19.25% and canopy dry weight by 11.34-65.57%. In general, the best treatment was the application of Mycorrhiza with OPEFB (Oil Palm Empty Fruit Bunch) compost.
