Arbuscular Mycorrhizal Fungi (AMF) form symbiotic associations with the roots of most vascular plants, helping to absorb water and nutrients. The objective of this work was to evaluate the occurrence of these fungi in three agroforestry systems and in an area of the Manaus Oil Refinery. Root samples were collected from 21 host species with five replications for AMF colonization assessments. Soil samples were collected to evaluate chemical characteristics. From the higher pH values and Ca and Mg contents in the soils of some areas, it can be inferred that there was an application of dolomitic limestone in the three Agroforestry Systems (AFSs) and, in the REMAN sites with mimosa and kikuyu. Root colonization with fungal hyphae was high in all areas, indicating that they contribute, at least partially, to plant nutrition and increased soil water absorption capacity.
