Short summary
Improving direct field measurement techniques to quantify gas emissions from large agriculture farm is challenging. We measured nitrous oxide (N2O) emissions with static closed chambers and slant open-path flux gradient (FG) approaches following chicken manure application. The concurrent emission ratios (FG / chamber) showed N2O fluxes measured by FG were 1.22-1.40 times higher than those from the chambers. This study provides important information for the agriculture gas measurement community.
