Effect of Temperature on Emission of Greenhouse Gases From Cow Manure

Fluxes of greenhouse gases emitted from cow manure in four different temperature treatments(5,15,25 and 35 ℃) were measured using closed-air-chamber-gas-chromatography to determine effect of temperature on the emission.Resutls show temperature is the main factor influencing the greenhouse gases emission from the manure.When the manure was low in temperature,greenhouse gases emission was less.The emission increased with the temperature.CO₂ emission varied sharply with the temperature,and so did CH₄ emission except for Treatments 5 and 15 ℃.In Treatment 35 ℃,N₂O emission was significantly higher than the others,while it did not vary much between the others.
