Abstract

This research was aimed at evaluating the status of soil nutrient NPK in rubber plantation PTPN VII Musi Landas. This research was carried out using a soil survey technique supported by site map at 1 : 50.000 scale. Soil samples were obtained from research location represanting six planting ages. Transect method was utilised from which three sampling points were observed and collected from individual age stands. Based on the laboratory analyses, soil Nitrogen content was generally low with concentrations approximately 0.08 to 0.18 %. Soil Phosporus was low to moderate with concentrations ranging from 5.70 to 19.50 mg/kg, while Potassium » • •• status was found low approximately 0.15-0.31 cmol/kg. Soil were acidic with pH values of 4.19 - 4.64, as also indicated by low concentration of calcium in soil (0.20 - 0.46 cmol/kg), and low magnesium (0.12 - 0.28 cmol/kg). The availability of soil nutrient may be improved through application of NPK fertilizers based on fix dosage and amount of fertilizer to get optimum rubber plant growth.
