No forum on world food security issues would be complete without a session on climate change and that was how the World Ag Congress concluded its roundtable discussions Wednesday.
While the issue may be debatable, there is no question that agriculture should be taking every opportunity to decrease greenhouse gas emissions – including carbon dioxide, methane and nitrous oxide. Panalist Jerry Hatfield with USDA’s National Soil Tilth Laboratory talked about how nitrogen stabilizers can make a major difference in nitrous oxide emitted from the application of nitrogen fertilizer. “Nitrous oxide is 320 times more powerful than CO2, so one molecule of nitrous oxide saved is like saving 320 carbon dioxide,” Jerry said. “So we can have a major impact on total greenhouse gas emissions by reducing nitrous oxide.”
Jerry told me that USDA-ARS has found that the use of stabilized nitrogen not only reduces emissions of nitrous oxide, but it is also better for plants because it makes nitrogen more available later in the season when the plant really needs it. “So, its a win-win – a win for the plant and a win for the environment simultaneously,” he said.
He says nitrogen stabilizers are readily available in various forms for farmers from companies like Dow and AGROTAIN.

Thanks to some much appreciated financial support from graduation monies, I have purchased some new gadgets to help me get my start. I bought a new MacBook and a Zoom H4 Recorder. Now the trick is getting accustomed to these new gadgets, and fast! A busy writer doesn’t have much time for reading instruction manuals, right?
And, now I have some questions. If you are a Mac user, what do you like best about them? What are your favorite tools on a Mac? Next, which editing software do you prefer for podcasts? Which ones are most user friendly?

The overall winner in the graduate category is Tung M. Che, a doctoral student at the University of Illinois at Urbana-Champaign, Illinois, USA who submitted a paper examining the Effects of mannan oligosaccharide on immune function and disease resistance in pigs. Both these winners are pictured in between Dr. Mark Lyons and Inge Russell.

It should be no surprise that sustainability is the most often used word here at the World Agricultural Forum’s World Ag Congress in St. Louis since the agriculture industry as a whole remains under the microscope when it comes to environmental issues.
