Respon Pupuk Guano Dan Mikoriza Dalam Memperbaiki Sifat Kimia Dan Hasil Kedelai Pada Tailing Tambang Emas Di Kabupaten Sijunjung

Abstract

Tailings are extracted materials that can pollute the environment, have a low cation exchange capacity (CEC) and nutrients. One of the efforts that can be done to improve its chemical properties is by applying guano and mycorrhizal fertilizers. The purpose of this study was to see the interaction between the use of guano and mycorrhizal fertilizers in improving the chemical properties and soybean yields in gold mine tailings. This research was conducted at STIPER Sawahlunto Sijunjung and continued at the Soil Science Laboratory Andalas University. The design used in this study was a completely randomized design (CRD) in factorial form with 3 replications where Factor A (dosage of guano fertilizer) A1: 0 ton/ a, A2: 10 tons/ha, A3: 15 tons/ha, A4: 20 tons/ha, A5: 25 tons/ha and Factor B (mycorrhizal dose) B1: 0 g/plant, B2: 10 g/plant, B3: 15 g/plant. The research data were analyzed statistically with the F test at the 5% real level. If the test results are not significantly different, then continue with the Duncan New Multiple Range (DNMRT) continued test at the 5% real level. From the research that has been done, it can be concluded that the use of guano and mycorrhizal fertilizers can improve the chemical properties and soybean yields in gold mine tailings.
