That steaming pile ain’t topsoil
U.S. scientists say they are starting a study to determine greenhouse gas emissions from feed yard operations.
Texas A&M University scientists at AgriLife Research in Amarillo, Texas, said they will measure three greenhouse gases: nitrous oxide, carbon dioxide and methane.
Assistant Professor Ken Casey and research chemist Al Caramanica said they will use a Varian gas chromatograph with three detectors set up for automatic injection of gas samples from gas-tight vials. That, they said, will allow simultaneous detection of all three gases from samples taken at feed yards.
“This work will focus primarily on nitrous oxide,” Casey said, noting the gas has approximately 310 times the global warming potential of carbon dioxide.
“We are part of a larger effort to quantify what emissions of greenhouse gas are from feed yards,” he said. “We want to understand the variability and circumstances that create the greatest emissions and determine methodologies that identify the right numbers. Then we want to help identify management practices that can keep them at the lowest possible levels.”
Sorry, I can’t help it. I don’t go out of my way to offend Texas readers of this blog – unless they’re some kind of reactionary git – which can happen anywhere. BUT –
Amarillo is the ultimo place on Earth to run these tests. If you’ve ever overnighted in Amarillo, say, during a nice hot July – you know the odors wafting from the feed lots scattered strategically in and around Amarillo can match any stench on the planet. My clients there used to joke that their biggest fear during a line storm wasn’t tornados; but, a lightning strike setting fire to the atmosphere!
