Performances of BRIS Soils Genesis and Classification in Terengganu, Malaysia

Abstract

The soils in the study area were found to be excessively well drained and too sandy. Thus, we wanted to determine how the BRIS soil in Merang is formed and how to improve its productivity. Intensive soil survey was applied in this research and soil sampling was taken and analyzed in laboratory for determining soil parameters. The research results showed that soil series are occurring side by side which relate the coexistence of beach ridges running parallel in different elevation to the seashore. Almost all profiles show no clear differentiation of horizons and are dominated by sand fractions (95-98 %), silt and clay contends are below 4%. According to soil taxonomy, Baging series are classified as Sandy, siliceous, isohyperthermic, typic, Quartzipsamments, Rhu Tapai is named as Sandy, siliceous, isohyperthermic, arenic, Alorthods, Rudua is identical with Sandy, siliceous, isohyperthermic, arenic, Alorthods and Jambu belongs to Sandy, siliceous, isohyperthermic, arenic, Alorthods.
