Populasi mesofauna tanah sangat dipengaruhi oleh ketersediaan makanan dalam lingkungan mereka. Sumber makanan dapat berasal dari bahan organik. Penelitian ini bertujuan untuk menentukan pengaruh jenis dan cara aplikasi bahan organik terhadap populasi mesofauna tanah pada piringan kelapa sawit. penelitian ini dilaksanakan di lahan perkebunan Pusat Penelitian Kelapa Sawit (PPKS) Aek Pancur, Tanjung Morawa. Penelitian ini menggunakan rancangan acak kelompok faktorial dengan dua faktor perlakuan. Faktor pertama adalah jenis bahan organik yang terdiri dari kontrol, serasah, TKKS, serasah + T. harzianum dan TKKS + T. harzianum. Faktor kedua adalah cara aplikasi yang terdiri dari disebar merata, ditumpuk melingkari tegakan dan diletakkan diujung piringan. Hasil penelitian menunjukkan bahwa pada minggu kedua, jenis bahan organik, cara aplikasi dan interaksi keduanya tidak berpengaruh nyata dalam meningkatkan populasi mesofauna, namun pada minggu keempat, keenam, kedelapan dan keduabelas pemberian bahan organik dalam bentuk TKKS, cara aplikasi disebar serta interaksi keduanya berpengaruh nyata dalam meningkatkan populasi mesofauna. Populasi tertinggi adalah di perlakuan B2A1 pada minggu keduabelas (4106 ind m-2).
Population of soil mesofauna is strongly influenced by the availability of food sources in their environment. Food sources may include various types of organic materials. This research aimed to determine the effect of types and technique application of organic materials on weed circle towards the population of soil mesofauna. This research was conducted in Indonesia Oil Palm Research Institute (IOPRI) plantations Aek Pancur, Tanjung Morawa. This research was use factorial randomized block design. The first factor was the types of organic material, i.e. without organic material, litter, Empty Fruit Bunch (EFB), litter + T. harzianum and EFB + T. harzianum and the second factor was the technique application of organic materials i.e. spread in palm circle, put around the stand of palm and put on the threshold of palm circle. The results showed that in week 2, type of organic materials, technique application and both interaction was not affect soil mesofauna population, but in week 4, 6 8 and 12 type of EFB, technique application spread in palm circle and both interaction could increase the population of soil mesofauna. The highest population was on treatment B2A1 in week 12 (4106 ind m-2).
