Effect of soil and fertilizer types on GHGs emission and plant growth in oil palm plantations

摘要

Carbon dioxide (CO_2) and nitrous oxide (N20) account for 56% and 7% of the total greenhouse gases (GHGs) emissions, respectively, with different values of global warming potentials. Oil palm production in Indonesia and Malaysia is currently the focusof debates concerning the potential impact to the environment via greenhouse gas emissions. Oil palm plantations have been reported to release large quantities of N_2O into the atmosphere, most likely linked to nitrogen fertilizer use. On the other hand, fertilizer input is necessary to achieve nutrient requirements for optimal growth and yields of oil palms on different soil. Therefore, it is essential to consider not only environmental impact but also the improvement in bunch yields in plantations. In this study we compare the effect of soil type with nitrogen fertilizer on N_2O and CO_2 flux and weight of fresh fruit bunch (FFB) of oil palm plantation.
