Literature data on N2O emissions

N2O emissions and fertilizer rates collected from a literature survey.

This datatable is part of the Meta-analysis of N2O emissions dataset. A meta analysis of reported N2O emissions as they relate to fertilizer input.

Variate Description Units
reference short reference to the paper
location location of the study
latitude latitude of the study lat-long
longitude longitude of the study lat-long
precipitation annual precipitation millimeter
mean annual temperature mean annual temperature in degree C. (Some studies reported multiple values so this is a text column instead of a numeric column.)
texture class the soil texture class
soil classification soil classification
sand percent sand in the soil %
silt percent of silt in the soil %
clay percent of clay in the soil %
soc soil organic carbon %
son soil organic nitrogen %
bd bulk density in g/cm^3 (this is a text column because some studies reported multiple values)
ph pH of the soil (this column is a text column because some studies reported multiple pH values)
crop the crop grown
management the agronomic management
number of measurements the total number of measurements taken number
method method of flux measurement
chamber area area of the chamber used squaremeter
measurements per sample the number of measurements taken to estimate a flux number
year the years the study was done
duration the study duration in days
number of replicates number of replicates number
fertilizer type type of fertilizer used
mode of fertilizer application method of fertilizer application
number of fertilizer applications number of fertilizer applications number
min nonzero n rate lowest N rate above zero used in the study kg/ha
max n rate maximum N rate used kg/ha
n rate nitrogen rate used kg/ha
total n2o emission total N2O emission kg/ha
standard error of n2o emission standard error of the N2O emission measuremtns kg/ha
emission factor emission factor (%)
emission factor change rate change in emission factor per kg N added per hectare
