Carbon Monoxide Emissions from Corn Silage

Carbon monoxide (CO) emissions from corn silage were observed using Fourier Transform Infrared (FTIR) spectroscopy and laser spectroscopy. In the first experiment, was produced laboratory bucket silos. Air samples collected silos during week of ensiling analyzed a low-resolution Bruker FTIR spectrometer coupled with long optical path length White Cell. The CO concentration in silo gas, derived spectra LINEFIT program, as high 48.0 ppm. second air through flux chamber an Ag-Bag pile on commercial dairy that opened several months after ensiling. high-resolution spectrometer, concentrations retrieved to be 6.83 ppm, corresponding area emission rate 33.7 mg/(hour ·m2). An LGR N2O/CO gas analyzer based infrared also used measure same chamber. Elevated these sources. present study revealed emitted by different phases Annual estimated much lower than those well-known categories San Joaquin Valley (SJV) California, but comparable food agricultural sources SJV. It is confirmed viable method for measuring complex mixtures, such gas.
