Work experience
My research project in the past emphasized in microbial activities in decomposition processes of organic material in compost pile and in the soil, especially in cellulolytic microorganisms and their enzyme activities, where this research project was received the best research result award in 1993. These microbial activities play the importance role in content and transformation of soil organic matter, soil carbon stock and some plant nutrient in soil. Another my research and development project, which directly involved on organic matter and carbon sequestration, was utilization of chemical fertilizers cooperated with organic fertilizers to restoration of soil quality and improvement of rice and some economic crop yield. This project emphasized in technology transfer from research activities to farmer in target areas and encourage them to produce organic fertilizer by themselves. The last importance project was estimation of carbon balance and soil carbon stock in application of soil and water conservation measures in agricultural area.
