(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."
