Abstract:
... Micrometeorological methods used to estimate emissions are advantageous because they are noninterfering and can integrate fluxes over large areas. They have not been routinely applied to beef cattle feedyards, where physical complexity and the possibility of disturbed air flow may be problematic. Our objective was to use the flux-gradient method to estimate NH3 emissions from beef cattle feedyard ...
