Arbuscular mycorrhizal fungi (AMF) are found in the vast of majority of terrestrial plant species, however their population and diversity are vary. This study was aimed at determining AMF population and it’s diversity at oil palm plantation both grown at mineral (government and smallholder plantations) and peat soil (private plantation). Soil samples were taken from 20 points for each plantation. At each point, top soil at 15 cm depth was collected inside and outside circle weeding for spore isolation and identification. Spores were isolated by wet sieving and decanting method using 350 and 45 µm sieves. Isolated spores were then counted manually under stereo microscope. Spore’s morphology and their reaction to melzer solution were used to identify AMF to genus level. Results showed that the highest spore population was found from mineral soil at smallholder plantation followed by peat soil and mineral soil at government plantation. There were 8 types of AMF found in mineral soil, while only 5 types at peat soil. Glomus type 3 and Acaulospora sp were the dominant AMF found in mineral soil while Glomus type 9 was the dominant AMF from peat soil. Results obtained also showed that the number of spore inside circle weeding was higher compared to outside circle weeding, however the AMF type found in both sides are the same.
