    Abstract

    The atmospheric CO2 concentration has increased during the last century and it is estimated that if some actions are not taken against this increase, current CO2 concentrations are expected to double before the end of this century. Plants and agricultural practices play important roles in atmospheric CO2 emission and fixation. Current study examined carbon fixation in oil palm. We hypothesized that good soil nutrient management practices could increase the absorption of atmospheric CO2, thereby mitigating the adverse effect of CO2 on climate. Study was carried out in small-holder oil palm plantation in South Sumatra, Indonesia, covering an area of 2,000 hectares. Values of fixed CO2 were determed by calculating the amount of CO2 accumuled in oil palm fresh fruit bunch (FSB). In spite of the fact that the soils in the study area had moderate available P, the were chemically infertile dute to low pH, low to very low content of total-C and N and low very low avaliability of K. Therefore, oil palm suffered from N and K deficiency but not P deficiency. Corrected NPK application (rate, time and method) increased oil palm production, thereby increasing the amount of atmospheric CO2 accumulation by oil palm. There results highlighted the importance of good nutrient management practices for the absorption of atmospheric CO2 and its' storage in plant biomass.
