  • Nitrogen soil tests - Do they always reflect what is going on?

    Do soil tests always reflect what’s going on? Emphatically, NO. The usefulness of nitrogen (N) soil testing is frequently a topic of discussion in both academic and farming circles. Those for the negative generally cite variability involved in sampling, lack of analytical laboratory accuracy and/or precision and lack of response calibration as factors that influence their position. While they ...

  • ASTM D3608 - 95(2011) standard test method for nitrogen oxides (combined) content in the atmosphere by the griess-saltzman reaction

    Both NO2 and NO play an important role in photochemical-smog-forming reactions. In sufficient concentrations NO2 is deleterious to health, agriculture, materials, and visibility. In combustion processes, significant amounts of NO may be produced by combination of atmospheric nitrogen and oxygen; at ambient temperatures, NO can be converted to NO2 by oxygen and other atmospheric oxidants. ...
