Physico-chemical properties of soil at oil palm plantation area, Labu, Negeri Sembilan

Abstract

A study on the physico-chemical characteristics of soil from oil palm plantation area at New Labu Estate, Negeri Sembilan was carried out. A number of 20 topsoil (0-20cm) samples were collected based on plantation block by using 'Dutch Auger'. The soil physico-chemical properties determined were particle size distribution, organic matter content, pH and total organic carbon. Particle size distribution was determined by pipette method and dry sieving. Bulk density was determined by waxing method. Organic matter and total organic carbon were measured through loss of ignition and Walkley-Black method, respectively. Soil pH was determined based on soil:water ratio of 1:2.5. Results showed that the texture of the soil was classified as sandy clay with the highest percentage of sand particles component. Organic matter content is considered as low at less than 4% and soil organic carbon content was low with 1.75%. The average soil pH in the study area was very acidic with values of 3.81.
