The study on soil quality in areas with and without vegetative cover aimed to compare soil characteristics in two locations: the Botanical Garden of Wichienmatu School and the Forest Conservation Unit in Trang Province (Yantakhao-Palian) The investigation focused on soil physical properties, temperature, moisture, pH, and soil nutrient content as indicators of soil quality. The study revealed differences in soil characteristics between areas with and without vegetative cover. In vegetated areas, the soil was loamy with an average temperature of 28.3 degrees Celsius, moisture content of 2.3, and a pH level of 6. Soil nutrient levels (N, P, K) were low. In non-vegetated areas, the soil was sandy loam with an average temperature of 27.5 degrees Celsius, moisture content of 5.5, and a pH level of 6. Soil nutrient levels (N, P, K) were higher than in vegetated areas. The study also observed higher temperature and lower relative humidity in the air at the Botanical Garden, contributing to higher soil moisture compared to the Forest Conservation Unit in Trang Province.
