Almaraz . reported that agricultural soils are a dominant source of NO pollution in California (20 to 32% of total statewide NO emissions). However, this conclusion may be undermined by the lack of agreement between their modeled estimates and previously reported empirical measurements, the extrapolation of NO fluxes during hot moments to derive annual estimates, and the overestimation of nitrogen fertilizer consumption in California.
阿尔马雷斯报告称，农业土壤是加利福尼亚州氮氧化物污染的主要来源（占全州氮氧化物排放总量的20%至32%）。然而，他们的模型估算与先前报告的实证测量结果之间缺乏一致性、将炎热时段的氮氧化物通量外推以得出年度估算值，以及对加利福尼亚州氮肥消费量的高估，可能会削弱这一结论。
