PT Agincourt Resources (PTAR) is developing research on mycorrhizal\nbioagents as an effort to improve the success of land reclamation and\nrestoration in the operational area of the Martabe Gold Mine, South\nTapanuli Regency, North Sumatra.<\/p>\n
Agincourt Resources\u2019 Biodiversity & Environmental Strategic\nDevelopment Manager, Syaiful Anwar, in Batang Toru on Friday, said\nmycorrhiza is being developed to help plants absorb nutrients and\nimprove their ability to grow, especially on soil media with limited\nnutrition.<\/p>\n
\u201cThe use of these bioagents is considered important given the land\ncharacteristics and environmental conditions around the mining area,\u201d he\nsaid.<\/p>\n
He said the research team sourced mycorrhiza from soil and plant\nroots in the natural forest of the Batang Toru area, then carried out\nisolation and spore enrichment.<\/p>\n
From this process, spore density, which was initially less than 100\nspores per 100 grams of soil, could be increased to around 400\u20131,000\nspores or more per 100 grams through the enrichment process.<\/p>\n
\u201cThe team then conducted response tests by comparing plants given\nmycorrhizal inoculum and plants without mycorrhiza,\u201d he said.<\/p>\n
Testing was then carried out to observe plant growth while ensuring\nmycorrhizal colonisation on the roots. Cultures showing good growth\nresponse and colonisation were subsequently declared suitable for\npropagation.<\/p>\n
According to him, the mycorrhiza development is directed at\nsupporting the nursery of local plants used in reclamation and\nrestoration.<\/p>\n
PTAR has currently developed around 76 types of local plants to\nsupport ecosystem recovery, including species that serve as food sources\nfor wildlife in the forest area.<\/p>\n
\u201cThis programme is not only aimed at making ex-mining land green\nagain, but also at forming an ecosystem that has species diversity and\nis able to support flora and fauna habitats,\u201d he said.<\/p>\n
In addition to reclamation, he continued, mycorrhiza development is\nalso being prepared to support the restoration of preservation areas as\nwell as environmental remediation research.<\/p>\n
The research team is currently studying the potential of certain\nmycorrhizal types in helping plants cope with metal-contaminated soil\nconditions and environments with certain acidity levels.<\/p>\n
He said the development of these bioagents is still in the research\nand development stage, including identification of mycorrhizal species\nthrough morphological observation and planned molecular or DNA\nanalysis.<\/p>\n
\u201cThe research results are expected to produce the right formula to\nsupport plant growth while reducing dependence on fertiliser use in land\nrecovery,\u201d he said.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/agincourt-resources-develops-mycorrhizal-bioagents-to-boost-mine-land-reclamation-1787320605", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
