## Abstract
The nickel post-mining soil with an open-pit mining system has poor soil chemical and physical properties.Thus, it requires appropriate site-specific management so that it can be optimized as a plant cultivation area.This study aimed to analyze the effectiveness of compost from oil palm empty fruit bunches (OPEFB) and mycorrhizal vesicular-arbuscular (MVA) in improving soil fertility of nickel post-mining soil.This study was conducted using a randomized block trial design with 2 factors.The first factor is compost with 3 treatments, consisting of 5 t•ha -1 (K1), 7.5 t•ha -1 (K2), 10 t•ha -1 (K3) and the second factor was mycorrhiza (M) in the fine-crushed brick carrier media with as many as 3 treatments consisting of 2 t•ha -1 (M1), 4 t•ha -1 (M2), 6 t•ha -1 (M3).A total of 9 treatment combinations were repeated 3 times, arranged in experimental pots at the Experimental Farm of Hasanuddin University, South Sulawesi, Indonesia.The results showed that the compost and MVA treatments had a significant effect on increasing the average values of cation exchange capacity, organic carbon, available P 2 O 5 , calcium and magnesium exchangeable,as well as decreasing exchangeable aluminum and iron.The highest soil properties values were found in the combination of compost 10 t•ha -1 (K3) and MVA 6 t•ha -1 (M3).The application of compost from OPEFB combined with MVA significantly improved soil fertility, which was indicated by improving soil chemical and biological properties.The application of MVA at various doses had a significant effect on the dry weight, root length of Calopogonium mucunoides and increase the number of MVA spores in the soil.
