Latest from the scientists

I got these from Alan Nations Blog.

Grasslands Absorb Methane E-mail
Monday, 26 April 2010
Research by Sydney University in Australia has found that healthy soil bacteria in well managed grasslands absorb more methane per day than a cow produces in a year. Professor Mark Adams, agricultural sustainability researcher and Dean of Agriculture at Sydney University told Australian Broadcasting Corporation that the findings are “a good news story and the farming community needs good news stories.” Adams said, “…we can say that grazing is a methane neutral or even methane positive land use.” He said in organically rich, well drained, well structured soils there were lots of bacteria willing to do this methane absorption work. This Australian research was reported in In Practice newslet
Three Labels Proposed For Organic Beef E-mail
Monday, 26 April 2010
A survey by Cornucopia Institute of organic beef producers found that 80% of organic producers do not confine their cattle to feedlots. Of these, 60 percent feed no grain at all and 20% feed some supplemental grain on pasture. The remainder use the standard industrial model of confinement feeding. Cornucopia said that many organic consumers would be surprised to learn that not all organic beef is grassfed and has proposed that the new USDA Organic label make the production practices of the producer clear to the consumer. Therefore, Cornucopia proposed three labels for USDA organic beef. They are: “Organic- Grain Finished,” “Organic- Pasture /Grain Finished,” and ” Organic – 100% Grassfed.” “We think the three-tier labeling system will help farmers and ranchers better develop their markets and consumers will gain transparency and choice in their consumption of organic meat,” said Mark Kastel of Cornucopia.
Grassfeeding Reduces Global Warming E-mail
Monday, 26 April 2010
Klause Betterbach-Bahl of the Karlsruhe Institute of Technology in Germany recently carried out a study on nitrous oxide production from the grasslands of Inner Mongolia. Nitrous oxide is the third most important greenhouse gas after carbon dioxide and methane. The researcher said he was surprised to find that nitrous oxide production was considerably lower from grazed grasslands than from ungrazed grasslands. “It’s been generally assumed that if you increase livestock numbers you get a rise in emissions of nitrous oxide. This is not the case, ” he said in Nature Magazine. He said that while grainfed animals generally are bad for the environment grassfed animals actually benefit it and consumers should make the distinction.

  1. The guy in the second article is WRONG. Grain finished animals produce 2/3 the amount of Greenhouse Gasses compared to grass fed. I wish people spouting off about these topics would get their stuff straight.
