High efficiency Nitrogen Study for Greenhouse gas Reduction through Agricultural Carbon Enhancement network in Fort Collins, Colorado
Nitrogen fertilization is essential for optimizing crop yields; however, it increases N2O emissions. The study objective was to compare N2O emissions resulting from application of commercially available enhanced-efficiency N fertilizers with emissions from conventional dry granular urea in irrigated cropping systems. These emissions were monitored from several irrigated cropping systems receiving N fertilizer rates ranging from 0-202 kg/ha years 2009-2011. Fertilizer types include Urea, UAN, SuperU (N inhibitor), ESN(slow release). In 2009, we eliminated the conventional tillage treatment. Cropping systems from 2009-2011 included a more conservative strip-till continuous corn (ST-CC) rotation and a no-till continuous corn (NT-CC) rotation. We also tested different fertilizer placements, including broadcast (bc), surface banded (bd) sub-surface banded (ssb) N inputs. Nitrous oxide fluxes were measured during these three growing seasons using static, vented chambers and a gas chromatograph analyzer. This work shows that the use of no-till and enhanced-efficiency N fertilizers can potentially reduce N2O emissions from irrigated systems.

在科罗拉多州弗特柯林斯，针对通过提升农业碳汇网络降低温室气体排放的高效氮素研究。氮肥施用对于优化作物产量至关重要；然而，它会导致氧化亚氮（N2O）排放的增加。本研究旨在比较商业可用的高效氮肥施用产生的N2O排放与灌溉作物系统中常规干颗粒尿素排放的差异。这些排放从2009年至2011年，接受0-202千克/公顷年氮肥施用率的多个灌溉作物系统中进行监测。肥料类型包括尿素、UAN、SuperU（氮抑制剂）和ESN（缓释）。在2009年，我们取消了常规耕作处理。2009年至2011年的作物系统包括更为保守的条带耕作连续玉米（ST-CC）轮作和无耕作连续玉米（NT-CC）轮作。我们还测试了不同的肥料施放方式，包括广播（bc）、表面条带（bd）和地下条带（ssb）氮输入。在这三个生长季节中，使用静态、通风室和气相色谱分析仪测量了氧化亚氮通量。这项研究显示，使用免耕和高效氮肥有可能减少灌溉系统中的N2O排放。本数据集包含以下资源：资源标题：科罗拉多州弗特柯林斯高效氮素研究（COFOARD3），CSV数据。文件名：COFOARD3_csv_data.zip，资源描述：实验单元、田地地点、温室气体通量、残留物管理、土壤化学、土壤物理、改良剂、播种、耕作、人员、处理、每日天气、气象站等CSV格式数据。
