A dataset with soil CO2 efflux measurements in two laboratory incubations at controlled temperature and moisture conditions.
Usage
data(eCO2)
Format
A data frame with the following 4 variables.
Sample
Sample code: AK_T25 is a soil from a boreal forest in Alaska incubated at 25 degrees C. HN_T35 is a soil from a temperate German forest (Hainich National Park) incubated at 35 degrees C.
Days
A numeric vector with the day of measurement.
eCO2mean
A numeric vector with the accumulated release of CO2. Units in mg C g-1 soil C.
eCO2sd
A numeric vector with the standard deviation of the accumulated release of CO2. Units in mg C g-1 soil C.
Details
Two laboratory incubation experiments where performed in April-May 2013 for a period of 42 days. Soil CO2 measurements were taken under controlled laboratory conditions. One soil was sampled at a boreal forest site (Caribou Poker Research Watershed, Alaska, USA) and the other from a temperate forest in Germany (Hainich National Park). For each soil 5 replicates were incubated and sampled. This dataset presents the mean and standard deviation of the measurements.
