摘要: The role of ammonia volatilization as a nitrogen loss mechanism in lowland rice (Oryza sativa L.) has recently been extensively reevaluated using techniques that do not disturb the field environment. This paper summarizes methodologies used this research and discusses findings from conducted micrometeorological studies on volatilization. Factors affecting contribution process to overall systems are also outlined. Suggestions for future included.
