Soil microbial indicators for efficient use of nitrification inhibitors. This project aims to improve understanding of the efficiency and governing factors of nitrification inhibitors in different agricultural soils. Nitrification inhibitors are widely used to improve nitrogen fertiliser efficiency and reduce greenhouse gas nitrous oxide emissions. However, their effectiveness varies across soil types. One possible reason is the different microbial communities in these soils. The project will address the key knowledge gaps of interactions between the nitrification inhibitors and the soil functional microbial communities. Anticipated outcomes are sound management strategies to improve fertiliser nitrogen use efficiency in Australian agricultural soils.

土壤微生物指标对硝化抑制剂的有效利用。本项目旨在提高对不同农业土壤中硝化抑制剂的效率和控制因素的认识。硝化抑制剂被广泛用于提高氮肥效率和减少温室气体一氧化二氮的排放。然而，它们的效果因土壤类型而异。一个可能的原因是这些土壤中的微生物群落不同。该项目将解决硝化抑制剂与土壤功能微生物群落之间相互作用的关键知识空白。预期的结果是健全的管理战略，以提高澳大利亚农业土壤的氮肥利用效率。
