Big-leaved acacia (Acacia mangium) is a species of woody plants in the Acacieae, long oval leaves, growing up to 30 m and straight stems, except in less favorable places will grow only 7-10 m, have hardwood, rough, longitudinal grooved and dark to light brown.
A. mangium has shoots with compound leaves consisting of many minor leaves and after growing a few weeks does not produce any more real leaves but the main axis of the petiole of each compound leaves widens and turns into known pohyllocladus or pseudo leaves.
This tree has about 142,000 seeds/kg. Long pods form circular threads and are black or brown when ripe. Dry pods will open to expose small black seeds. Trees bind nitrogen to the soil and are a popular species for agroforestry projects.
This plant is weather resistant, although it requires special care if it is planted as a garden plant where the leaves are falling a lot. These plants include legumes that grow quickly by increasing height 4 m per year near the equator, do not require high requirements and are not so affected by soil types.
Strong wood and economic value for finishing and home furnishings including cabinets, door frames, windows and good for fuel. Shiny and smooth surface after polished also to make parquet tiles. A. mangium which is seven years old produces wood that can be made for good particle boards.
