Additionally, methane and nitrous oxide emission would be reduced substantially.

此外，甲烷和一氧化二氮排放量将大幅减少。

And a new study shows that biochar could have an impact on agriculture's other greenhouse gas emission: nitrous oxide, or laughing gas, which is no laughing matter when it comes to climate change.

一项最新研究表明生物炭对诸如一氧化二氮、笑气之类由农业生产造成的温室气体排放可能会产生影响，这些气体的排放对气候变化来说可不是什么好事。

The emission of methane and nitrous oxide is largely the result of agricultural activities; nitrous oxide from fertilisers and methane mostly from cows.

甲烷和一氧化二氮的排放主要是农业活动的结果：一氧化二氮源于化肥而甲烷主要来自奶牛。
