Soil greenhouse gases emission from conservative/non-organic farming management of Harum Manis

Abstract

Agriculture production has been identified as a major contributor to atmospheric greenhouse gases (GHG) on a global scale with about 14% of global net carbon dioxide (CO2) emission coming from agriculture according to Intergovermental Panel on Climate Change (IPCC) Assessment Report. The purposed of this study to observe temporal variation of GHG concentrations particularly carbon dioxide (CO2) and methane (CH4) from soil in the Harum Manis plantation under non-organic farming practice. The second objective of the study is to study the concentration of GHG under different soil conditions, such as soil moisture, pH, temperature and effect of rainfall. Static chamber was deployed to capture the GHG produce from the soil of Harum Manis crop production. The gas sampling was conducted in 9 week and the highest average of CO2 emission recorded at 2nd week with 9750 ppm and CH4 at 9th week with 5000 ppm. The GHG sample was transferred from each chamber into 1L tedlar bag before analysed with Gas Analyser 5000 (GA5000) to determine concentration of CH4 and CO2. By determine the amount of GHG emission from soil of crop production, it assist researcher to control or reduce the GHG emitted from agriculture to atmosphere. This study has revealed that the concentration GHG emission from non-organic/conventional farming can be determine by using chamber method and several parameter such as soil moisture, soil pH, soil temperature and amount of rainfall related to the amount of GHG concentration emission from soil of Harum Manis plantation management practice.
