Soil respiration on Horqin meadow was studied in 2010 using a special device. The researchers found that soil respiration follows a daily pattern, peaking at 2:00 PM and dropping in the morning. It is highest in summer and lowest in winter. Soil temperature is closely linked to soil respiration, explaining 81.9% of the changes. The Q10 value, a measure of how temperature affects respiration, was 2.92. Roots contribute 6.6% to 29.4% of soil respiration, averaging at 18.9%.
