Reducing Nitrous Oxide Emissions with Enhanced Efficiency Nitrogen Fertilizers in Wheat Production in Manitoba, Canada

<p>This project summarizes data from six site-years for a field study in Manitoba, with the aim of quantifying and comparing the application time (fall, spring) and source (EEF, non-EEF) effects on cumulative N<sub>2</sub>O emissions and agronomic measurements of Canadian hard red spring wheat in southern Manitoba, Canada.</p>

<p>Core ideas from the study include: 1) At five out of six sites which had an N source effect on N<sub>2</sub>O emissions, eNtrench and SuperU were the most optimal products which reduced cumulative N<sub>2</sub>O emissions than conventional urea by 54% and 43%, respectively. 2) Combining fertilizer N sources, N<sub>2</sub>O emissions from fall treatments were similar to spring at four of six sites. 3) Grain yield was generally not affected by fertilizer N sources; 4) Grain yields and protein from fall applications were generally similar or lower than spring.</p>

<p>This data publication includes all observations (location, agronomic management, grain yield, cumulative N<sub>2</sub>O emissions, and N removed with grain for each treatment-site-year). The dataset contains 384 observations for each variable of grain yield, cumulative N<sub>2</sub>O emissions and N removed with grain, which were collected at six sites in Manitoba over crop years from 2015 to 2017.</p>
