Nitrous oxide flux from wheat (National Agricultural Nitrous Oxide Research Program), Horsham, Victoria Australia, 2014. [Theme 5: Reducing emissions through improved nitrogen use efficiency]

This data package contains nitrous oxide flux data as well as relevant soil and crop production parameters for a wheat crop grown at Vectis, Victoria, Australia in 2014. These measurements were undertaken as part of the 'Improving nitrous oxide abatement in high rainfall cropping systems' project. The objectives of this project are: - To evaluate the effectiveness of different nitrogen abatement management strategies (including nitrification and urease inhibitors and timing of fertiliser applications) on crop nitrogen uptake and losses as nitrous oxide and other forms of nitrogen from the soil:plant system. - To assess the responsiveness of grain crops in south-east Australia to nitrogen fertiliser applications in relation to different soil organic matter and nitrogen levels. The data is separated into four broad categories:
1) Climate data for the 2014 season.
2) Soil description including key physical and chemical parameters and land use history.
3) Nitrous oxide flux data including soil monitoring at the time of sampling.
4) Crop production data.

本数据集包含2014年于澳大利亚维多利亚州韦克蒂斯（Vectis）种植的小麦作物的一氧化二氮（nitrous oxide）通量数据，以及配套的土壤与作物生产参数。相关测量工作作为“高降雨种植系统一氧化二氮减排改进”项目的一部分实施。该项目的目标如下：
1. 评估不同氮肥减排管理策略（包括硝化抑制剂、脲酶抑制剂及施肥时机）对作物氮素吸收效率，以及土壤-植物系统中以一氧化二氮和其他形态氮素形式流失的氮素的调控效果；
2. 评估澳大利亚东南部谷类作物针对不同土壤有机质与氮素水平的氮肥施用响应性。
本数据集共分为四大类别：
1. 2014生长季气候数据
2. 土壤概况，包含关键物理、化学参数及土地利用历史
3. 一氧化二氮通量数据，包含采样阶段的土壤监测数据
4. 作物生产数据
