Soil incubation data along a water gradient

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 72 days. The predominant soil is 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. Four treatments with four replicates were set up at the SWC of 12%, 24%, 43% and 61%, respectively. The average cumulative respiration of the four replicates and its standard deviation (SD) are provided in the dataset.

这个数据集来源于一项培养实验，该实验在黑暗条件下进行，温度为15°C，相对湿度为40%，持续72天。优势土壤类型为砂壤土，砂、粉砂（silt）和黏粒（clay）的占比分别为54%、41%和5%。0-10 cm土层的土壤有机碳（SOC）含量为4.2%，pH值为6.9。设置了4个处理组，每组4次重复，土壤含水量（SWC）分别为12%、24%、43%和61%。数据集中提供了4次重复的平均累积呼吸量及其标准差（SD）。
