2-3 A horizon cores taken at each cardinal direction using a single Holm Oak as a center point, either underneath the tree canopy, or 3 m outside of it.
all Profiles are in the same mountain area; coordinates only estimation from figure 1
c_org data (might be from same profile as SA_1981, but depth increments appear slightly different)
Carbonate content of topsoil is 4%; soil pH is 5
Carbonate content of topsoil is 4%; soil pH is 8
Carbonate content of topsoil is 5%; soil pH is 7.7
composite; 20 randomized soil cores (0 to 10 cm depth) were collected from a randomly chosen 25×25 m soil plot and mixed
downslope under banana plantation; ca. 10 years old; slash and burn sites
For each land use (profile) 3 50x50m blocks were selected and 10 samples were taken and put into a composite at each block.
He_Science_2016_ profile_14; depth for carbon stock is approximate
midslope under Job's tears; in winter area is planted with rice; slash and burn sites
number is plot number for EBIS AmeriFLux
observation year is not mentioned in the study, but an observation year of 1986 was adapted from the old template from Yujie He´s compilation; also there is some uncertaintz about depth increments - in methods authors say they sampled first in 10 cm increments, then in 20 cm, but the depths of points extracted from graphs was not clearly following this pattern
original pit damaged, resampled 4 meters away in 2002
pre-contact Hawaiian agricultural sites that are under modern pasture
profile name is plot name for EBIS-AmeriFlux on profile name transect under AmeriFlux tower
profile sampled from same pit, but different depth intervals for isotopic analysis
radiocarbon analysis performed for only 3 of 9 pits
reference pasture sites off of historic agricultural areas
soil taxonomy is best guess from web soil survey (not in manuscript or USGS-OFR)
subsequently sugarcane land abandoned in 1985; fertilized with NPK since 1920 (see paper for details)
summit under secondar forest; ca. 20 years old; slash and burn sites
The reported profile is a composite of many samples throughout the site. Three independent radiocarbon measurements were taken for each horizon, each from a separate composite of samples, so each is independent. But the rest of the profile characteristics are only reported once, so the radiocarbon mean (reported) is used for the layer, and the independent replicates are given as fractions.
This profiles represents pre-bomb (house built in 1956 prevented input of bomb carbon); Radiocarbon profile more representative of 1956 than sample year
Three pits were dug centered ~10 m from the datalogger box, which itself was located~30 m from the tower base.
