Under the supervision of the advisor, the students conducted a study on soil quality around the large Ram Yai tree at the Trang Agricultural Research and Development Center, Palian District, Trang Province. The study involved measuring the soil’s acidity–alkalinity (pH). In addition, soil temperature and moisture were measured to assess the suitability of the soil conditions in the area surrounding the tree.
The study of soil quality around Ram Yai trees was conducted at the Ram Yai area of the Trang Agricultural Research and Development Center, Palian District, Trang Province. The objectives of this study are as follows :1) To investigate the soil structure in the Ram Yai tree area,2) To examine the soil pH, 3) To measure soil temperature, and 4) to determine soil moisture. The study was carried out using measurement methods based on the GLOBE program guidelines. Soil samples were collected and analyzed for soil structure, soil pH, and soil moisture around the Ram Yai trees. The results showed that the soil in the Ram Yai tree area had a uniform structure, which was granular soil. The soil pH was slightly acidic, the soil temperature was 30°C, and the soil moisture was 10%.
