ABSTRAK Tanaman kelapa sawit ditanam hampir pada semua jenis tanah seperti gambut, liat berlempung dan lempung berpasir dengan proporsi kandungan tiap tekstur tanah berbeda-beda dilapangan. Cendawan mikoriza arbuskular (CMA) merupakan mikroorganisme tanah yang berperan sebagai mikroba perombak, membantu tanaman dalam penyerapan unsur hara dari tanah. Penelitian ini bertujuan mengidentifikasi jenis dan populasi spora mikoriza pada beberapa tekstur tanah dipertanaman kelapa sawit. Penelitian dilakukan pada 3 (tiga) lokasi perkebunan kelapa sawit di Kabupaten Sampit, Kalimantan Tengah, yaitu di lahan PT. Sapta Karya Damai (SKD), PT. Agro Bukit dan areal pertanaman kelapa dan kelapa sawit milik petani di Samuda besar. Penelitian dilaksanakan pada bulan Maret sampai dengan Juni 2015. Pengambilan contoh tanah dilakukan secara Purposive Sampling. Analisis contoh tanah dilakukan di Laboratorium Pengujian Balittro - Bogor. Parameter yang diamati, yaitu pH, kelembaban tanah, jenis dan jumlah populasi spora mikoriza. Hasil penelitian menunjukan bahwa mikoriza yang ditemukan adalah dari jenis Glomus dengan populasi bervariasi menurut jenis tanah, yaitu berkisar antara 175,3 - 283 buah per 100 mg tanah. Populasi tertinggi, yaitu 283 spora per 100 mg tanah ditemukan pada jenis tanah gambut di perkebunan kelapa sawit PT. Agro Bukit yang belum berproduksi (umur 10 tahun). Kata kunci : Cendawan, mikoriza, tekstur, tanah, kelapa sawit. Identification of The Fungie Micorhyza Asbuscular on Saveral Soil Textures at Oilpalm Plantation, Central Kalimantan ABSTRACT Oil palm trees planted in virtually all types of soil such as peat, clay and sandy clay with argillaceous proportion of the content of each soil texture is different in the field. Arbuscular mycorrhizal fungie (FAM) is a soil microorganisms that act as microbial crusher, helps plants to absorb nutrients from the soil. This study aims to identify the types and populations of mycorrhizal spores in soil texture on oilpalm plantation. The study was conducted at three (3) locations oil palm plantations in the district of Sampit, Central Kalimantan, namely in te area of PT. Sapta Karya Damai (SKD), PT. Agro Bukit and coconut plantations and oil palm farmers in Samuda Besar. The experiment was conducted in March and June 2015. Soil sampling is purposive sampling. Analysis of soil samples carried out in the Laboratory Testing Balittro - Bogor. The parameters observed were pH, soil moisture, type and number of mycorrhizal spores population. The results showed that mycorrhizae are found are of the type Glomus with a population varies according to the type of soil ranged between 175.3 to 283 pieces per 100 mg of soil. The highest population, namely 283 spores per 100 mg of soil found in the peat soil types in PT. Agro Bukit oil palm plantations wihich is not yet in production ( 10 years). Keywords : Fungi, michorrizal,textur, soil, oil palm.
