Emissions of N 2 O and NO from fertilized fields: Summary of available measurement data

Information from 846 N 2 O emission measurements in agricultural fields and 99 measurements for NO emissions was summarized to assess the influence of various factors regulating emissions from mineral soils. The data indicate that there is a strong increase of both N 2 O and NO emissions accompanying N application rates, and soils with high organic‐C content show higher emissions than less fertile soils. A fine soil texture, restricted drainage, and neutral to slightly acidic conditions favor N 2 O emission, while (though not significant) a good soil drainage, coarse texture, and neutral soil reaction favor NO emission. Fertilizer type and crop type are important factors for N 2 O but not for NO, while the…
