Abstract : The experimental site selected for this study was located in Laopi terrace, Pingtung Hsien. The main soil type in this area is Lateritrc soil. There were six regions classified based on vegetations grown in the field. The soil was sampled from each regions to analyze and compare the physical and chemical properties. The results indicated that the soil bulk density was higher in samples taken from litchi garden, pasture, and pineapple garden. The pH values from the shaw and pineapple garden were lower than others. The soil organic matter from litchi garden and pineapple garden was higher than that from the pasture, Machilus zuihoensis, mango garden and the shaw. The hydraulic conductivity from Machilus zuihoensis and mango garden was the highest, followed by the shaw, pineapple garden, pasture and litchi garden. The soil chemical and physical properties varied from different depths of the soil profile. The range of the soil bulk density was from 6 to 30%, the soil organic matter was from 30 to 40%, and the soil hydraulic conductivity was from 77 to 88%, respectively. The changes of these three soil properties were significantly different among the sampled regions.
