Abstract

Oil palm cultivation is increasingly carried out on suboptimal land, such as Ultisols. Application of ameliorant such as biochar and compost may be chosen as an alternative to solve the problem occurred on this sub optimal soil. This study aims to determine the optimal dosage of a mixture of oil palm empty fruit bunch (EFB) biochar, poultry manure compost, and Rock Phosphate (RP) to enhance soil quality and support the growth of one-year-old oil palm plants. The study was conducted over six months in a one-year-old oil palm plantation located in Panca Mulya Village. A randomized Complete Block Design (RCBD) was employed with the aplication of biochar, compost, and rock phosphate (RP = Togo Rock Phosphate, 33.5% P₂O₅) in the following treatments: P0 = control (no treatment); P1 = biochar 20 tons.ha-1 + RP 200 kg.ha-1; P2 = biochar 10 tons/ha + compost 10 tons.ha-1 + RP 200 kg.ha-1; P3 = compost 20 tons.ha-1 + RP 200 kg.ha-1; P4 = biochar 20 tons.ha-1 +compost 10 tons.ha-1 + RP 200 kg.ha-1; P5= biochar 10 tons.ha-1 + compost 20 tons.ha-1 + RP 200 kg.ha-1. Results indicated that the application of biochar, compost, and RP, whether individually or in combination, enhanced oil palm growth compared to the control. The application of biochar and compost improved soil physical properties, increased soil organic matter content, total pore space, available water content, reduced bulk density, soil penetration resistance, and promoted oil palm growth. The best treatment was found to be 10 tons.ha-1 biochar + 20 tons.ha-1 compost + 200 kg.ha-1 RP. Keywords: ameliorant, empty fruit bunch, soil quality

Abstract

Penelitian bertujuan mengevaluasi dampak aplikasi pupuk kandang ayam dan abu boiler terhadap perbaikan pH tanah, ketersediaan fosfor (P-tersedia) serta hasil tanaman kedelai (Glycine max L.) pada Ultisol. Studi ini dilakukan dari Agustus hingga Januari di pekarangan Nusa Grand Abadi, Kecamatan Kota Baru, Kota Jambi, Provinsi Jambi. Rancangan Acak Kelompok (RAK) digunakan berdasarkan arah kemiringan lahan, terdiri dari enam perlakuan: A1 = 5 t/ha pupuk kandang ayam; A2 = 5 t/ha pupuk kandang ayam + 2,5 t/ha abu boiler A3 = 5 t/ha pupuk kandang ayam + 5 t/ha abu boiler; A4 = 10 t/ha pupuk kandang ayam; A5 = 10 t/ha pupuk kandang ayam + 2,5 t/ha abu boiler; dan A6 = 10 t/ha pupuk kandang ayam + 5 t/ha abu boiler. Ada 24 petak percobaan karena setiap perlakuan diulang empat kali. Ditanami 75 tanaman kedelai per petak, dengan 8 tanaman sampel per petak, sehingga total 192 tanaman sampel dihasilkan. pH tanah, kadar P-tersedia, tinggi tanaman, jumlah polong per tanaman, dan hasil biji kedelai per petak adalah semua faktor yang diamati. Untuk setiap variabel yang daiamati, analisis ragam (ANOVA) dan uji lanjut DMRT pada taraf 5% digunakan untuk menganalisis data. Hasil analisis statistik menunjukkan bahwa pupuk kandang ayam dan abu boiler memiliki efek signifikan. Untuk mencapai hasil terbaik, komibinasi 10 t/ha pupuk kandang ayam dan 5 t/ha abu boiler digunakan. Ini meningkatkan pH tanah, P yang tersedia dan hasil kedelai.
