Researchers used a special system to measure how much carbon dioxide is released from the soil in fenced grasslands in Xilamuren. They found that the amount of carbon dioxide released from the soil changed throughout the day, with the highest amount in the afternoon and the lowest at night. The amount of carbon dioxide released also depended on the temperature and moisture in the soil. When the soil was very dry or very wet, less carbon dioxide was released. They also discovered that the rate of carbon dioxide release increased as the soil got warmer, but only up to a certain point. This information can help us better understand how carbon is cycled in grasslands, especially as the climate changes.
