RECLAMATION OF COAL MINING USED LAND THROUGH OBSERVATION ON EFFECTIVINESS OF ARBUSCULAR MYCORRHIZAL FUNGI ON CORN PLANTS IN GREENHOUSE

Abstract

Mining activities cause detrimental effects on environments and until now there has not been a maximum effort to rehabilitate the condition. When this condition is not improved very soon, it will cause disaster for human. Mining activity is often started with land clearing and its vegetation, digging soil layers and coal materials, and piling up of soil that can cause negative impacts on environments. To improve the environment impact right away there should be an effort to be implemented that can support sustainable agricultural development in Indonesia. One method is application of natural fertilizer like Arbuscular Mycorrhizal Fungi (AMF) on corn as a host plant. The objective of research was to determine optimal dose of AMF that could give the highest growth and yield of corn using soil from coal mining used land in Sumatera Barat. The research was done in a greenhouse and laboratory. The result indicated that application of AMF inoculants with a dose of 40 gr/pot either in mono or multispores could increase corn yield in coal mining used land
