This environmental science research, titled "A Study of Soil Quality Characteristics Affecting the Growth of Proh Hom (Kaempferia galanga L.) at Wichienmatu School, Trang Province," aimed to1) study soil structure characteristics 2) analyze soil nutrient content, specifically Nitrogen (N), Phosphorus (P), and Potassium (K) 3) examine light intensity 4) determine pH levels (acid-base)5) study temperature and humidity and 6) observe the growth of Proh Hom within the Wichienmatu School area. Measurements of soil structure, nutrients, light intensity, pH, temperature, and plant growth were conducted following the GLOBE Thailand protocols.
The findings revealed that regarding soil nutrients, Site 3 had higher average Nitrogen and Potassium levels than Sites 1 and 2, while Site 1 recorded the highest average Phosphorus. In terms of soil environment, Site 3 showed the highest average soil moisture and pH levels, whereas Site 2 recorded the highest average temperature. For light intensity, Site 2 had a higher average than Sites 1 and 3. When considering the growth characteristics of Proh Hom—including plant height, leaf length, and leaf count—it was found that Site 3 had the highest overall average growth, followed by Site 2 and Site 1, respectively. In conclusion, Site 3 is the most suitable location for the overall growth of Proh Hom.
