Tangerines (Citrus reticulata var. Tejakula) were destroyed in 1984 by CVPD, allegedly because the use of chemicals was too intensive, resulting land degradation. Since ten years ago, these oranges have been successfully cultivated again using healthy organic cultivation, but farmers difficulty getting fertilizer. This research aimed to identify and isolate Arbuscular Mycorrhizal Fungi (AMF) on tangerines cv. Tejakula, their colonization roots effect soil fertility.
