PERUBAHAN SIFAT TANAH DI BAWAH TEGAKAN Acacia mangium Wild PADA AREAL HTI PT. FINANTARA INTIGA KABUPATEN SINTANG
Abstract: Estabilishment of
plantation forest (HTI) is one of the land rehabilitation program in Indonesia.
The goal of HTI program is to reclaim land for this purpuse. This research aims
to characterize physical and chemical change in soil after the reclamation with
Acacia mangium Wild. This research employed the survey method, and soil
sampling was done purposively. Data were analyzed using a complete random
design (RAL). Result show that there were changes in soil physical and chemical
properties in area planted with Acacia mangium Wild. C-organic, N-total, K, pH,
and porosity of soil increased after the HTI program. Also, soil texture
getting improved. P decreased during early planting was decreased, possibly
because it used in large amounts for plant growth. After the 6th year after
planting the P content started to increase. This is possibly because Acacia
mangium Wild partly died-off and dead plant part decomposed and released P to
the soil.
