Soil water content is essential for plant growth. The availability of water in the soil is always depending on soil characteristics, plant species that cover the land surface and amount of radiation that reach the surface. A study of soil moisture was conducted in the Pasoh 50 ha plot to assess the variations of water content for three different sites. The selected sites are dry, wet and ridge areas. Soil moisture contents were measured at various depths ranging from 15 to 75 cm below the ground. The FDR (Frequency Domain Reflectometry) technique was used to measure the soil moisture directly at the site. The average soil moisture based on two years period of monthly measurement varies between plots with 48% for dry alluvial, 56% for ridge and 68% for wet alluvial. However, maximum moisture was recorded for wet alluvial at 100 % followed by ridge at 92 % and dry alluvial at 80 %.
