Arbuscular mycorrhizal fungal inoculation improves Nauclea orientalis L. growth dan phosphorus uptake in gold mine tailings soil media

Abstract

Gold mine tailing soil media are characterized by low soil fertility and heavy metals toxicity. As an effort to improve the condition of gold mine tailing soil media, a revegetation experiment using Arbuscular Mycorrhizal Fungi (AMF) and soil media from gold mine tailing was conducted in the greenhouse. The objectives were to assess initial growth, P uptake and Pb reduction in Nauclea orientalis L. plants inoculated with indigenous AMF grown on gold mine tailing soil media. Three AMF fungi were used in this study, i.e. Glomus aggregatum, Glomus sp. and Acaulospora delicata. The experiment was conducted in Completely Randomized Design, having four treatments, i.e. control, G. aggregatum, Glomus sp. and A. delicata. The experiment was carried out for 3 months in a greenhouse scale. The results showed that local AMF inoculation significantly increased the height and stem diameter of lonkida by 181-213% and 284-443%, respectively, compared to control. The highest measurements of leaf's length and width of lonkida seedlings were obtained from Glomus sp. and A. delicata treatments. Glomus sp. and A. delicata each significantly increased P levels in roots and shoots. Inoculation with G. aggregatum reduced Pb in the root and shoots parts by 74-86% and 72-76%, respectively, compared to controls. Local AMFs are potential to be developed as biological fertilizers to support revegetation in degraded lands, such as in gold mine tailing areas.

Composition and diversity of arbuscular mycorrhizal fungi spore associated with different land-use types in tropical gold mine

“…AM fungi can be beneficial for plant life and growth in a variety of biotic and abiotic environmental conditions, such as salinity (He et al, 2019), drought (Zhang et al, 2019), heavy metal toxicity (Husna et al, 2019) and waterlogging (Tuheteru et al, 2015). In addition, AMF is also potential to be developed as a tool for vegetation, reforestation, and restoration program in degraded ecosystems (Wang, 2017) and for phytoremediation process for land contaminated with organic and inorganic materials (Tuheteru et al, 2016;2020).…”

Diversity of arbuscular mycorrhizal fungi in asphalt post-mining land in Buton Island, Indonesia

“…C. claroideum was the most dominant species isolated with high occurrence and the highest Importance and Shannon-Wiener Diversity Indices. This species is thought to be dominant because of: 1) having a small spore size 2) having the ability to sporulate (spore production) in various environmental conditions; 3) having the ability to adapt to various soil and climatic conditions as well as the ability to produce inoculum (propagules) (Shukla et al 2013;Husna et al 2015;Tuheteru et al 2019Tuheteru et al , 2020a. Gigaspora is also found on post-mining land which is polluted with pollutants (Husna et al 2016;Tuheteru et al 2020b).…”

“…AMF are reported to have the ability to accelerate the restoration of various post-mining lands in the world. Acceleration mechanisms by AMF include increasing nutrient and water acquisition and plant tolerance, improving soil structure and quality, sequestration of heavy metals, and maintaining ecosystem stability and function (Lone et al 2016;Wang 2017;Husna et al 2021a, b;Tuheteru et al 2020a;Manjula et al 2022). In particular, publications related to AMF as a restoration tool have been reported by several other researchers (Asmelash et al 2016;Wang 2017;Neuenkamp et al 2019;Aavik et al 2021).…”

The effectiveness of Arbuscula Mycorrhyza Fungi stater with different fortification in increasing the productivity of Clitoria ternatea on saline soil

“…This shows that AMF is very effective in helping plants to overcome salinity stress, AMF is very effective in providing nutrients for plants even though the fertilizer used is 50% dose. According Mansur et al [14] mycorrhizal fungi can absorb nutrients such as P, N, K, Zn, Cu, and Fe in saline soil conditions. The dry weight of the canopy of Clitoria ternatea aged 9 weeks can be seen in Table 4.…”
