KAJIAN SIFAT TANAH PADA LOKASI PENANAMAN INTENSIF KAWASAN TAMAN NASIONAL BUKIT BAKA BUKIT RAYA

Abstract

In an effort to restore the function of forests that have been damaged, the TNBBR is carrying out intensive planting activities in the framework of restoring the ecosystem at km 33 starting in 2021. The planting is carried out in the context of improving the ecosystem, namely improving soil properties. This study aims to examine the conditions of differences in physical and chemical properties of the soil at intensive planting locations in the context of ecosystem restoration at km 33 Belaban Resort SPTN Region I Nanga Pinoh Bukit Baka Bukit Raya National Park. The implementation of this research began with taking soil samples for ± 3 effective days in the field from 16-18 March 2023. Sampling was carried out at three locations, namely intensive planting locations, open forest and secondary forest. Sampling of soil at each location is intact and composite. Intact soil was collected using a sample ring and composite soil collection using a hoe with a soil depth of 0-20 cm at three points. Analysis of physical properties (Bulk Density, texture) and soil chemistry CEC (Cation Exchange Capacity), C-Organic, N-Total, C/N Ratio) was carried out at the Chemistry and Soil Fertility Laboratory and Soil Physics Laboratory, Faculty of Agriculture, University of Tanjungpura. The results of laboratory analysis of the parameters of the physical and chemical properties of the soil in each field will be compared using analysis of variance with SPSS 26. In intensive planting there are significant differences in the physical properties of the soil compared to open forest and secondary forest, while the chemical properties of the soil are different but not significant or not real.
