Increasing nitrous oxide emissions from soil to the atmosphere are a concern as they contribute to global warming and the destruction of the ozone layer. While 70-81% of this increase has been attributed globally to agricultural soils, the factors controlling emissions from arable soils in southern Australia are not well understood. We aim to characterise and model the relationship between the soil microbial community responsible for nitrous oxide emissions and soil water availability. Understanding the processes responsible for nitrous oxide emissions will enable us to change the way we manage our semi-arid soils so as to minimise nitrous oxide emissions.

越来越多的一氧化二氮从土壤中排放到大气中，这是一个令人关切的问题，因为它们有助于全球变暖和臭氧层的破坏。 虽然全球70-81%的增长归因于农业土壤，但控制澳大利亚南部可耕地土壤排放的因素尚不清楚。 我们的目标是建立和模拟土壤微生物群落之间的关系，负责一氧化二氮的排放和土壤水的可用性。 了解一氧化二氮排放的过程将使我们能够改变我们管理半干旱土壤的方式，从而最大限度地减少一氧化二氮的排放。
