Using spatially variable nitrogen application and crop responses to evaluate crop nitrogen use efficiency

Using spatially variable nitrogen application and crop responses to evaluate crop nitrogen use efficiency

Low nitrogen use efficiency (NUE) is ubiquitous in agricultural systems, with mounting global scale consequences for both atmospheric aspects of climate and downstream ecosystems. Since NUE-related soil characteristics such as water holding capacity and organic matter are likely to vary at small sca...
