Perubahan Penggunaan Lahan Hutan Alam Menjadi Hutan Tanaman Industri Acacia crassicarpa Terhadap Beberapa Sifat Fisika Tanah Gambut

Abstract

The purpose of this research was determine how the effect of lands use change from natural forest to plantation forest Acacia crassicarpa on some physical properties of peat soil.The research wasconducted by survey method, with purposive sampling. Data was analysed by descriptive and graphics model. The parameters were particle size distribution, bulk density, particle density and porosity. The result of research show that land use change from natural forest to plantation forest Acacia crassicarpa was increasing total of smalles particle, bulk density, and particle density, while the porosity decreases. The longer time of land use change was increasing the decomposition of the peat soil, which improves the physical peat soil.
