Abstract
The high concentration of nitrogen and potassium in effluent of rubber processing can be utilised as fertiliser for crops such as oil palm. A study was carried out to monitor the effects of effluent on the chemical physical and microbiological properties of the soil during the initial two years of application in areas planted with oil palm. Effluent application revealed higher content of potassium in the soil compared to the fertiliser-applied soil. The effluent also enriched the soil to a depth of 20 cm with organic carbon and total nitrogen as compared to the fertilised soil. Concentrations of total phosphorus total magnesium and total calcium of the effluent-applied soil were comparable to the fertiliser-applied soil. Cation exchange capacity of the soil applied with effluent was higher than the fertiliser-applied soil but the difference was not significant. Total bacteria and fungi population of the effluent-applied soil were comparable to the fertiliser-applied soil. The fertiliser-applied soil had a significantly higher population of ammonium oxidiser than the effluent-applied soil.
