Status of Arbuscular Mycorrhizal Fungi in the Poboya Gold Mine Area, Palu Municipality, Central Sulawesi

Abstract: Gold mining in Indonesia is carried out using an open-pit mining system, which has an impact on the loss of forest vegetation, soil properties in mining areas, loss of flora and fauna, as well as the occurrence of slopes that change hydrological conditions and soil fertility levels. The problem that often occurs is that post-mining land is difficult to grow plants due to the lack of nutrient content which results in plant death. Exploring the types of AMF in the vegetation composition in the mining area is an important initial study and is necessary to be able to identify and map the dominant and specific types of AMF that exist in the vegetation composition in the area. The aim of this research is to determine the status of arbuscular mycorrhizal fungi and vegetation composition in the Poboya gold mine area. The research was carried out from February 2023 to June 2023. Observations of vegetation types and taking soil and root samples were carried out on agroforestry land and secondary forest in the Poboya gold mining area, Palu Municipality, Central Sulawesi. Identification of arbuscular mycorrhizal fungal microbes was carried out at the Forest Biotechnology Laboratory, Bogor Agricultural Institute (IPB), Bogor, West Java. Analysis of soil properties was carried out at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University, Palu. The research results showed that there were 5 types of AMF spores found at the research location, namely Acaulospora sp2, Acaulospora sp3, Acaulospora sp4, Glomus sp6, Glomus sp7. The results of observing the color of the spores showed that there were different types of spore colors including clear yellowish, yellow and brown. The density of Arbuscular Mycorrhizal Fungi spores was highest at the agroforestry research location, 11 spores were found per 20 g of soil, while at the secondary forest research location only 3 spores were found per 20 g of soil. The colonization level shows that the plants with the highest percentage of AMF colonization are white teak (Gmelina arborea Roxb) (91.8%) and Candlenut (Aleurites moluccana (L.)) (51.3%), the medium colonization level is Lamtoro (Leucaena leucocephala ) (33.7 %) Vegetation composition In secondary forest areas the number and types of species are higher than in agroforestry areas. The highest relative density at each growth phase is found in agroforestry land, namely in Candlenut (Aleurites moluccana (L.)) and Lamtoro (Leucaena leucocephala.) plants.
