Research on the existence of Arbuscular Mycorrhizal Fungi On the Anthocephalus cadamba at Peat Land Plantation aims to obtain information were of the type AMF. Soil and root samples were taken at 5 points at 0-20 cm depth, using quadrant circle design with 1 to 2 meter radius. Results characterization of AMF found that two genera Glomus, and Acaluspora, there are 8 Glomus sp types spores, and 3 Acaulaspora types spores. The number of spores found 3753 spores / 500 g peat soil with mean 745 spores. The number of spores of the highest in the sample P4 1128 spores / 100 g of peat and lowest sample P1 385 spores / 100 g of peat.
