Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dan dosis terbaik dari batuan fosfat alam terhadap pH, Al-dd, dan P-Tersedia. Penelitian dilaksanakan di lahan percobaan Universitas Jambi dengan jenis tanah Ultisol. Analisis sampel Tanah dilaksanakan di Laboratorium Kimia tanah dan Kesuburan Tanah Fakultas Pertanian Universitas Jambi. Penelitian dilaksanakan mulai dari bulan Oktober 2021 hingga Januari 2022. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Perlakuan yang diberikan meliputi : P0 = 0 kg/ha fosfat alam (kontrol), P1 = 150 kg/ha fosfat alam, P2 = 300 kg/ha fosfat alam, P3 = 450 kg/ha fosfat alam, P4 = 600 kg/ha fosfat alam. Hasil penelitian menunjukkan bahwa pemberian fosfat alam 450 kg/ha mampu meningkatkan pH, menurunkan kada Al, dan meningkatkan P-Tersedia pada tanah ultisol. This study aims to determine the effect and the best dosage of rock phosphate nature to pH, Al-dd, and Available-P. The research was carried out in an experimental field Jambi University with Ultisol soil type. Soil sample analysis was carried out in the Laboratory of Soil Chemistry and Soil Fertility, Faculty of Agriculture Jambi University. The research was carried out from October 2021 to January 2022. This research was conducted using a randomized design Complete (CRD) with 5 treatments and 5 replications. The treatment given include: P0 = 0 kg/ha natural phosphate (control), P1 = 150 kg/ha natural phosphate, P2 = 300 kg/ha of natural phosphate, P3 = 450 kg/ha of natural phosphate, P4 = 600 kg/ha of natural phosphate. The results showed that giving natural phosphate 450 kg/ha was effective increase the pH, decrease the Al content, and increase the P-Available in the soil ultisol.
