Abstract

The importance of enrichment planting by planting suitable tree species in degraded forests and land is to restore soil biological function. These actions have been done at Takasago UNIMAS Educational Forest. However, factors such as soil fertility, waterlogged condition, competition with existing trees, and light intensity differences influence the forest's tree growth rate. The study was conducted at Enrichment Planting 2019 site, where the areas were planted with Shorea macrophylla and Durio zibethinus through line planting in 2019 with four chosen plots that have different light intensity and tree growth rates which are (i) shaded with good growth, (ii) shaded with bad growth, (iii) unshaded with good growth, and (iv) unshaded with bad growth. The study was conducted through soil profiling by adopting the International Soil Science Society (ISSS) and site observation to determine the difference in soil morphological properties at selected plots. The in-situ data such as soil horizon, color, root, rock, structure, and texture were recorded on the soil profile recording sheet. The result shows that the four chosen plots show the observations on the sites and different characteristics that influence the growth of trees. There was better growth in the shaded area, plot 1, due to charcoal, while in the unshaded area, plot 3, due to enough light intensity. In contrast, there was bad growth in shaded area, plot 2 due to low light intensity and shrub growth, while in the unshaded area, plot 4, due to termites present in the soil. In conclusion, each chosen plot with different sunlight exposure and growth rate shows different soil morphological characteristics.
