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

越来越多的一氧化二氮从土壤排放到大气中是一个令人担忧的问题，因为它们会导致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，但控制南澳大利亚耕地土壤排放的因素尚不清楚。我们的目标是描述和模拟负责一氧化二氮排放和土壤水分有效性的土壤微生物群落之间的关系。了解导致一氧化二氮排放的过程将使我们能够改变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。

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.
