    Abstract
    Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beberapa sumber bahan organik dan masa inkubasi terhadap pH, C-organik, N-total, P-total dan K-dd pada tanah Ultisol. Penelitian ini dilakukan di Laboratorium Fisika Tanah, Fakultas Pertanian, Universitas Sumatera Utara. Rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap Faktorial yang terdiri dari 2 faktor dengan 3 ulangan. Faktor I : bahan organik (B) yaitu : B0 (tanpa bahan organik), B1 (kompos paitan 10g/pot), B2 (kompos kulit durian 10g/pot), B3 (kompos Tandan Kosong Kelapa Sawit/TKKS 10g/pot), B4 (pupuk kandang ayam 10g/pot), B5 (kompos paitan 5g/pot + pukan ayam 5g/pot), (kompos kulit durian 5g/pot + pukan ayam 5g/pot), B7 (kompos TKKS 5g/pot + pukan ayam 5g/pot) dan Faktor II ialah lama inkubasi (I) yaitu : I1 (inkubasi tiga minggu) , I2 (inkubasi empat minggu). Hasil penelitian menunjukkan pemberian beberapa sumber bahan organik berpengaruh nyata dalam meningkatkan terhadap pH, C-organik, N-total, P-total dan K-dd tanah. Perlakuan masa inkubasi berpengaruh nyata dalam meningkatkan pH tanah. Interaksi antara beberapa sumber bahan organik dan masa inkubasi berpengaruh nyata dalam meningkatkan pH tanah. Perlakuan terbaik terdapat pada perlakuan kompos Tithonia dan pupuk kandang ayam dengan dosis 20 ton/ha.
     
    The objective of this study is to determine the effect of some organic matter and incubation period on the pH, C-organic, total-P, total-N and K-exchange on Ultisol. This research conducted in Soil Physics Laboratory, Faculty of Agriculture, University of North Sumatra. This study used completely randomized design which consist of two factors with three replications. Factor I: organic matter (B) ie : B0 (without organic matter), B1 (compost of paitan 10g/pot), B2 (compost of durian skin 10g/pot), B3 (Compost of Oil Palm Empty Fruit Bunch 10g/pot), B4 (chicken manure 10g/pot), B5 (compost of paitan 5g/pot + chicken manure 5g/pot), (compost of durian skin 5g/pot + chicken manure 5g/pot), B7 (Compost of Oil Palm Empty Fruit Bunch 5g/pot + chicken manure 5g/pot) and factor II : the incubation period (I), ie : I1 (three weeks incubation), I2 (four weeks incubation). The results showed that application of some organic matter and the incubation period significantly increased soil pH, C-organic, total-P, total-N and K-exchange. The incubation period significantly increased soil pH. The interaction between organic matter and incubation period significantly increased soil pH. The best treatment was the application compost of Tithonia and chicken manure with dose 20 tons/ha.
