Summary
This study investigates the potential of locally sourced arbuscular mycorrhizal fungi to improve the establishment and nutrient acquisition of Pterocarpus indicus, a native tropical timber species, in severely degraded asphalt post-mining soils in Indonesia. By using indigenous AMF isolates, the research addresses the challenge of revegetating nutrient-poor, structurally compromised mining substrates where conventional planting approaches often fail. The findings are likely to demonstrate that AMF inoculation confers measurable improvements in plant growth and mineral nutrition compared to uninoculated controls, supporting the use of bioinoculants in ecological restoration programmes.
UK applicability
The specific findings relate to tropical post-mining land restoration in Indonesia and are not directly transferable to UK conditions; however, the underlying principles of AMF inoculation to enhance plant establishment on degraded or low-fertility soils are relevant to UK land reclamation, brownfield restoration, and agroforestry research.
Key measures
Plant height (cm); shoot and root biomass (g); AMF root colonisation rate (%); leaf/tissue nutrient concentrations (N, P, K, and potentially micronutrients, mg/kg or %)
Outcomes reported
The study measured growth performance and nutrient uptake of Pterocarpus indicus (narra/angsana) seedlings inoculated with local arbuscular mycorrhizal fungi (AMF) in degraded asphalt post-mining soils. It likely reported plant height, biomass, root colonisation rates, and macro- and micronutrient concentrations in plant tissue.
