Abstrakt: This study aims to evaluate the effect of forest ecosystem on soil properties in a natural reforestation area of Thai Royally-Initiated Khao Cha-Ngum deteriorated area. The forest ecosystem has changed tremendously over 20 years. It changed from degraded forests to dry dipterocarp forests (flat ground and south) and mixed deciduous forests (north, east and west). Soil in the west is different from others because tree species in the west aspect area is more diverse than others. It has equal accumulation of organic matter throughout the soil profile; whereas the accumulation of organic matter of others is in A horizon. Mineral composition of the south, east and west soils contained goethite indicating that these soils were more humid than the flat ground and north soils. Soil micromorphological characteristics indicated that all soils had highly activities of soil organisms. Natural reforestation for a long time has a distinct effect on soil formation in relation to the variety of trees because trees affect the soil moisture, quality and quantity of the litter.
