Oil palm replanting has faced environmental criticism as it is a source of carbon dioxide (CO‚‚) emission. The aim of this study was to determine the level of CO‚‚ emissions and the value of carbon stocks for oil palm smallholders replanting. The measurements were taken using the infrared gas analyser (IRGA) method for CO‚‚ emission. Non-destructive methods were used to measure carbon stocks for oil palm-stands while destructive methods were used for understorey and intercropped plants. This study shows that there was dynamic of CO‚‚ emission during the replanting averaging (t CO‚‚ ha yr) 28.5 for 28-year-old oil palm 59.0 for bare land after land clearing 47.0 for intercropped plants in the vegetative phase 51.6 for intercropped plants in the generative phase and 42.9 for one-year-old oil palm. It was found that CO‚‚ emissions were reduced due to the conditions of land coverage and that the reduction in CO‚‚ emissions occurred not only because of the absorption of CO‚‚ by plants for photosynthesis but also due to being stored away as much of the carbon stock (t C ha) was found in corn (10.2) legume cover crops (7.6) soyabeans (3.5) and natural vegetation (2.8). In 28-year-old oil palm it was found to be at 74.7.

Abstract

Oil palm replanting has faced environmental criticism as it is a source of carbon dioxide (CO‚‚) emission. The aim of this study was to determine the level of CO‚‚ emissions and the value of carbon stocks for oil palm smallholders replanting. The measurements were taken using the infrared gas analyser (IRGA) method for CO‚‚ emission. Non-destructive methods were used to measure carbon stocks for oil palm-stands while destructive methods were used for understorey and intercropped plants. This study shows that there was dynamic of CO‚‚ emission during the replanting averaging (t CO‚‚ ha yr) 28.5 for 28-year-old oil palm 59.0 for bare land after land clearing 47.0 for intercropped plants in the vegetative phase 51.6 for intercropped plants in the generative phase and 42.9 for one-year-old oil palm. It was found that CO‚‚ emissions were reduced due to the conditions of land coverage and that the reduction in CO‚‚ emissions occurred not only because of the absorption of CO‚‚ by plants for photosynthesis but also due to being stored away as much of the carbon stock (t C ha) was found in corn (10.2) legume cover crops (7.6) soyabeans (3.5) and natural vegetation (2.8). In 28-year-old oil palm it was found to be at 74.7.
