Inconsistencies undermine the conclusion that agriculture is a dominant source of NOx in California

Impact/Purpose:
The purpose of this publication is to reply to a recent research paper in Science Advances. Almaraz et al. (Advances, 31 January 2018) reported that agricultural soils are a dominant source of NOx pollution in California. However, this conclusion may be undermined by the lack of agreement between their modeled estimates and previously reported empirical measurements, the extrapolation of NOx fluxes during hot moments to derive annual estimates, and the over-estimation of nitrogen fertilizer consumption in California.
