Abstract

Ultisol merupakan tanah yang memiliki masalah kemasaman tanah, bahan organik rendah dan nutrisi makro yang rendah dan memiliki ketersediaan P yang sangat rendah, kapasitas tukar kation (KTK) rendah, kejenuhan basa (KB) dan C- organik rendah, kejenuhan Aluminium tinggi, fiksasi P tinggi, kandungan besi dan mangan yang dapat meracuni tanaman, dan peka erosi. Pemupukan dengan pupuk organik dan anorganik merupakan cara terbaik dalam meningkatkan kesuburan tanah Ultisol sehingga tanaman Kedelai yang tumbuh diatasnya dapat produktif. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Jambi, Desa Mendalo Indah, Kecamatan Jambi Luar Kota, selama 3 bulan dari bulan Maret sampai dengan bulan Juni 2021. Penelitian menggunakan rancangan acak kelompok dengan satu faktor perlakuan yaitu: A0 = tanpa perlakuan, A1 = pupuk organik 10 ton ha-1, A2 = pupuk organik 10 ton ha-1 dan 50% anorganik rekomendasi, A3 = pupuk organik 10 ton ha-1 dan 100% anorganik rekomendasi, A4 = pupuk organik 20 ton ha-1 , A5 = pupuk organik 20 ton ha-1 dan 50% anorganik rekomendasi, A6 = pupuk organik 20 ton ha-1 dan 100% anorganik rekomendasi, sehingga menghasilkan 7 perlakuan dan 3 ulangan. Parameter yang diukur adalah c-organik tanah, pH tanah, Al-dd tanah, P-Tersedia tanah, serta hasil tanaman Kedelai. Hasil penelitian menunjukkan bahwa pemberian pupuk organik dan pupuk anorganik dapat meningkatkan c-organik tanah, meningkatkan pH tanah, menurunkan Al-dd tanah, meningkatkan P-Tersedia tanah serta meningkatkan hasil tanaman Kedelai. Ultisols are soils that have soil acidity problems, low organic matter and low macronutrients and have very low P availability, low cation exchange capacity (CEC), low base saturation (KB) and low C-organic, high Aluminum saturation, P fixation high, contains iron and manganese which can poison plants, and is sensitive to erosion. Fertilization with organic and inorganic fertilizers is the best way to increase Ultisol soil fertility so that the soybean plants that grow on it can be productive. The research was conducted in the experimental garden of the Faculty of Agriculture, University of Jambi, Mendalo Indah Village, Jambi Outer City District, for 3 months from March to June 2021. The study used a randomized block design with one treatment factor, namely: A0 = no treatment, A1 = fertilizer organic fertilizer 10 tons ha-1, A2 = organic fertilizer 10 tons ha-1 and 50% inorganic recommendation, A3 = organic fertilizer 10 tons ha-1 and 100% inorganic recommendation, A4 = organic fertilizer 20 tons ha-1 , A5 = fertilizer 20 tons ha-1 organic and 50% inorganic recommendations, A6 = organic fertilizer 20 tons ha-1 and 100% inorganic recommendations, resulting in 7 treatments and 3 replications. Parameters measured were soil c-organic, soil pH, soil Al-dd, soil-available P, and soybean yield. The results showed that the application of organic fertilizers and inorganic fertilizers can increase soil c-organic, increase soil pH, reduce soil Al-DD, increase soil available P and increase soybean yields.
