Abstract

The dataset is from an incubation experiment which was carried out in the dark at the temperature of 15°C and the relative humidity of 40% for approximately three months. The predominant soil sampled from a temperate grassland of northern China, it is chernozem and belongs to sandy loam, with sand, silt and clay percentages of 54%, 41% and 5%, respectively. The SOC content of the 0-10 cm layer is 4.2% and the pH is 6.9. This study manipulated soil water levels and the intensity of water variability with a total of six treatments. There were four replicates for each treatment for gas sampling. The average cumulative CO2 release and the soil aggregate of the four replicates and its standard error (SE) are provided in the dataset. One additional group of destructive samplings and the soils for the gas sampling were collected at the wet end and dry end in the last drying-rewetting cycle, respectively. 14 phospholipid fatty acids (FLFA) markers were selected from the combination results of the wet and dry ends in the last drying-rewetting cycle.
