Abstract

Abstrak. Usaha pertanian di Ultisol akan menghadapi sejumlah permasalahan karena Ultisol umumnya mempunyai pH rendah yang menyebabkan kandungan  Al, Fe, dan Mn terlarut tinggi sehingga dapat meracuni tanaman. Pemupukan dengan pupuk organik dapat mengatasi kendala untuk meningkatkan produktivitas tanah ultisol, salah satunya berupa vermikompos. Vermikompos adalah pupuk organik yang diperoleh melalui proses yang melibatkan cacing tanah dalam proses penguraian atau dekomposisi bahan organiknya. Penelitian ini bertujuan untuk mempelajari pengaruh pemberian vermikompos terhadap perbaikan sifat kimia tanah Ultisol. Penelitian ini dilaksanakan di Laboratorium Kimia Tanah Fakultas Pertanian Universitas Syiah Kuala, Laboratorium Penelitian Tanah Tanaman dan Balai Pengkajian Teknologi Pertanian. Penelitian berlangsung pada Maret sampai Oktober 2017. Penelitian ini dilakukan dengan menggunakan metode Rancangan Percobaan (Experimental Design) dengan Rancangan Acak Lengkap (RAL) non faktorial. Faktor perlakuan adalah dosis vermikompos yaitu: V0 = 0 ton/ha-1, V1 = 15 ton/ha-1, V2 = 20 ton/ha-1, V3= 25 ton/ha-1  dan V4  = 30 ton/ha-1. Masing-masing perlakuan diulang sebanyak 4 kali. Parameter yang diamati adalah pH (H2O dan KCl), C- Organik, N total, P tersedia, Al-dd, dan C/N. Hasil penelitian menunjukkan bahwa vermikompos dapat mempengaruhi beberapa sifat kimia tanah Ultisol Jantho. Pemberian vermikompos pada tanah Ultisol nyata meningkatkan P tersedia pada 3 dan 5 MSI, dan nyata meningkatkan C-Organik tanah pada 3 MSI. Pemberian vermikompos pada tanah Ultisol tidak memberikan pengaruh nyata terhadap pH, Al-dd, N total, dan C/N.The Effect of Giving Vermicompost on the Changes of  Chemical Characteristic of UltisolAbstract. Farming in Ultisol will face a number of problems because Ultisols generally have low pH which causes high Al, Fe and Mn content that can poison the plants. Fertilization with organic fertilizer can overcome the obstacles to increase ultisol productivity, one of them is vermicompost. Vermicompost is an organic fertilizer that obtained through a process involving earthworms in the process of or decomposition of organic matter.The aim of this research is to study about the effect of vermicompost toward improving the chemical characteristic of Ultisol. This research was conducted at Soil Chemistry Laboratory of Agricultural Faculty of Syiah Kuala University, Land Research Laboratory and Agricultural Technology Assessment Institute. The research took place from March to October 2017.This research is done by using Experimental Design method with non factorial Random Design (RAL). The treatment factor was vermicompost dose: V0=0 ton/ha-1, V1=15 ton/ha-1, V2=20 ton/ha-1, V3=25 ton/ha-1 and V4=30 ton/ha-1. Each treatment was repeated 4 times. The parameters observed were pH (H2O and KCl), C-Organic, N total, P available, Al-dd, and C/N. The results showed that. Using vermicompost on Ultisol soil increase P available at 3 and 5 MSI, and significantly improve on C-Organic soil at 3 MSI. Using vermicompost on Ultisol soil did not have significant effect on pH, Al-dd, N total, and C / N.
