Stem and soil respiration in fertilised plots in the Central Amazon, 2017-2019

The dataset contains stem respiration (ppm) of 320 trees with DBH (Diameter at breast height) > 26 cm, measured with the EGM-4 (Environmental Gas Monitor for CO2). Data were collected on October 2019. In relation to the soil respiration dataset, it contains soil respiration (µmol CO2m-2 s-1) of different type of collars placed on the forest floor, and measured with the LI – 8100 A soil respiration system. Data were collected from June 2017 to October 2019. In both activities, leak tests were done before collections. All research was conducted in a field site approximately 80 km north of Manaus, in the state of Amazonas, Brasil.

本数据集收录了320棵胸径大于26厘米的树木的茎部呼吸量（ppm），该数据通过EGM-4（二氧化碳环境气体监测器）进行测量。数据采集于2019年10月。与土壤呼吸量数据集相关联，本数据集还包括了置于森林地面的不同类型颈圈所测得的土壤呼吸量（µmol CO2m-2 s-1），该呼吸量通过LI – 8100 A土壤呼吸系统进行测量。数据采集时间跨度为2017年6月至2019年10月。在两次采集活动之前，均进行了泄漏测试。所有研究工作均在位于巴西亚马逊州马瑙斯市以北约80公里的野外场地进行。关于本数据集的详细信息，请参阅https://doi.org/10.5285/591e3708-7ff1-483b-9156-15c721c00daf。
