资源简介：
To quantify the magnitude of soil nitrous oxide flux and the drivers of nitrous oxide emissions in a representative central Iowa corn-soybean agricultural system, we measured greenhouse gas emissions (N2O and CO2) from 2017 to 2019 (primarily using custom automated chambers) along with soil chemical and physical parameters across a topographic gradient in a typically managed agricultural field near Ames, Iowa, USA. More details can be found in the associated manuscript, Lawrence et al. (2021).
