Integrating microbiology and climatic drivers to determine triggers for nitrous oxide emissions from arable soils in semi-arid Western Australia.

从土壤向大气排放的一氧化二氮增加是一个令人担忧的问题，因为它们加剧了全球变暖和臭氧层的破坏。虽然这一增长的70%-81%归因于全球农业土壤，但澳大利亚南部耕地土壤的排放控制因素尚未得到很好的了解。我们的目标是描述和模拟负责一氧化二氮排放的土壤微生物群落和土壤水有效性之间的关系。了解造成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，从而将一氧化二氮排放降至最低。

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.
