Natural revegetation of tailing deposited on agricultural area in Buru, Maluku

Abstract

Tailing deposited on rice field in Burn District Indonesia poses a severe environment problem since rice does not grow on tailing with low fertility. The aim of this study was to verify the natural vegetation grown naturally on mercury contaminated tailing which covered the top soil of rice field, as well as the development of legume tree, Trembesi, Rain Tree (Albizia saman F. Muell) grown in purpose between the pioneer plants. Plant succession observations were carried out for 2,5 years on 524 m2 of rice fields. As presumed, the succession was similar to the general pattern of primary revegetation. The study area increased diversity of weed as primary vegetation which influenced the better growth of Trembesi. A total of 17 natural plants were recorded as pioneer weed as well as late colonizer. Weed grazing by livestock, mainly cow, promoted the diversity of plants due to their role as seed dispersal agents.

“…Pioneer plants grown in disturbed land contribute to soil characteristics improvement that support growth of subsequent plants. Revegetation Avaliable at: www.ijlsar.org by biological has been performed in 2017 in limited area of tailing in agricultural area (Hindersah et al, 2019). After three years, pioneer plants were naturally grown but, in some location, they failed to grow (Figure 1).…”
