N2O Emissions from cotton crop. Kingsthorpe, Queensland, Australia 2009-10 [Theme: Filling the research gap. Round 2]

Soil N2O fluxes from cotton were monitored over one season with an automated measuring and analysis system allowing for a high temporal resolution. Emissions were measured from different irrigation intesities according to the following experimental set up:
3 different irrigation treatments:

Fully-irrigated (I-50%). The crop will be irrigated when 50% of the plant available water capacity (PAWC) is depleted.

Deficit-irrigated 1 (I-60%). The crop will be irrigated when 60% of the PAWC is depleted.

Deficit-irrigated 3 (I-85%). The crop will be irrigated when 85% of the PAWC is depleted.

N2O emissions were measured with the closed chamber method with 3 replicates per treatmet for the period from November 2009 to May 2010

本数据集针对棉花田土壤氧化亚氮（N₂O）通量开展单季作物生长期原位监测，采用具备高时间分辨率的自动化测量与分析系统完成数据采集。本研究依据下述实验设计，针对不同灌溉强度处理组开展氧化亚氮排放监测：
1. 充分灌溉组（I-50%）：当土壤中50%的植物有效持水量（Plant Available Water Capacity, PAWC）被消耗时，即对作物进行灌溉；
2. 亏缺灌溉1组（I-60%）：当土壤中60%的植物有效持水量被消耗时，即对作物进行灌溉；
3. 亏缺灌溉3组（I-85%）：当土壤中85%的植物有效持水量被消耗时，即对作物进行灌溉；
本研究于2009年11月至2010年5月期间，采用静态箱法（closed chamber method）进行氧化亚氮排放监测，每组处理设置3次生物学重复。
