Increasing soil organic matter can enhance crop productivity, but it can also enhance nitrous oxide (N2O) and Methane (CH4) emission, the potent greenhouse gases (GHGs), by increasing application of nitrogen (N) and Carbon (C) to the soil. Nitrous oxide and CH4 are contribute to global warming by destroying or removing the troposphere and stratosphere of the ozone layer. The major source of N2O and CH4 is the agriculture sector, and their global warming potential is 25 which is 298 times more than that of carbon dioxide (CO2). The effort has been conducted to escalate nitrogen use efficiency by additional substrates in synthetic nitrogen fertilizer, e.g., use of organic material and nitrification inhibitors through an optimized fertilizer utilization rate to reduce negative environmental impact of N2O losses to atmosphere and NO3- leaching. The current report was to investigate role of addition of organic matter to emission of GHGs, soil microbial community and crop production in the South- Sulawesi Province, Indonesia
