    Abstract
    The first thing that must be known to study the potential of vesicular arbuscular mycorrhizal is to know the diversity of these organisms. Data of diversity vesicular arbuscular mycorrhizal used to obtain the selection of of potential and effective isolates. The aim of this research was to know the density of spore, colonization percentage, and types of vesicular arbuscular mycorrhizal of oil palm tree in PTPN III Batang Toru Estate at different soil fertility conditions. Methods of soil and root were sampling directly from the field (Afdeling I, II, and III) and trapping. The soil chemical characters was observed at Laboratory of Research Technology, Faculty of Agriculture, North Sumatera University. The observation chemical of the soil showed that the soil conditions in all of Afdeling are less fertile. The highest number of spores were found in the field and trapping in Afdeling I; 248 and 336 spores/50 g soils respectively. Percentage of vesicular arbuscular mycorrhizal colonization were highest in Afdeling I by 42%. Vesicular arbuscular mycorrhizal spores knowed that there consisted of two genera Glomus (42 types) and Acaulospora (3 types).
     
    Hal pertama yang harus diketahui untuk mempelajari potensi fungi mikoriza arbuskula adalah mengetahui keanekaragaman dari organisme tersebut. Dengan adanya data keanekaragaman fungi mikoriza arbuskula, maka dapat dilakukan seleksi guna mendapatkan isolat fungi mikoriza arbuskula yang potensial dan efektif. Penelitian ini bertujuan untuk mengetahui kepadatan spora, persentase kolonisasi, dan tipe fungi mikoriza arbuskula pada areal tanaman kelapa sawit PTPN III Kebun Batang Toru dengan kondisi kesuburan tanah yang berbeda. Metode pengambilan sampel tanah dan akar dilakukan secara langsung dari lapangan (Afdeling I,II dan III) serta trapping. Pengamatan sifat kimia tanah dilakukan di Laboratorium Riset dan Teknologi Fakultas Pertanian Universitas Sumatera Utara. Hasil pengamatan sifat kimia tanah menunjukkan bahwa kondisi tanah pada ketiga Afdeling tergolong rendah. Jumlah spora tertinggi dari hasil lapangan dan tarpping diperoleh pada Afdeling I, yaitu masing-masing 248 dan 336 spora/50 g tanah. Persentase kolonisasi fungi mikoriza arbuskula yang tertinggi juga pada Afdeling I, yaitu 42%. Tipe spora fungi mikoriza arbuskula yang diperoleh terdiri dari dua genus, yaitu Glomus (42 tipe) dan Acaulospora (3 tipe).
