'Grassroots action' in livestock feeding to help curb global climate change

(Burness Communications) In a series of papers…, scientists offer new evidence that a potent chemical mechanism operating in the roots of a tropical grass used for livestock feed has enormous potential to reduce greenhouse gas emissions.
Referred to as "biological nitrification inhibition" or BNI, the mechanism markedly reduces the conversion of nitrogen applied to soil as fertilizer into nitrous oxide, according to papers prepared for the 22nd International Grasslands Congress. Nitrous oxide is the most powerful and aggressive greenhouse gas, with a global warming potential 300 times that of carbon dioxide.
"Nitrous oxide makes up about 38 percent of all greenhouse gas emissions in agriculture, which accounts for almost a third of total emissions worldwide," said Michael Peters… "BNI offers what could be agriculture's best bet for keeping global climate change within manageable limits."
