How much is soil nitrous oxide emission reduced with biochar application? An evaluation of meta‐analyses

This data file includes five datasets used to construct the following five
figures. Fig. 1. Response ratios (RR) of biochar application on soil N2O
emissions from the meta-analyses and grand mean of RR and its 95%
confident interval. Number on the right side is the total number of
experiments used for RR calculation. Fig. 2. Impacts of experimental
setting including experiment type (a), ecosystem type (b), and
experimental duration (c) on the response ratios (RR) of biochar
application on soil N2O emi­­­ssions. Number on the right side is the
total number of experiments used for RR calculation. Fig. 3. Impacts of
biochar properties including feedstock (a), pyrolysis temperature (b), pH
(c), and C:N ratio (d) on the response ratios (RR) of biochar application
on soil N2O emi­­­ssions.  Number on the right side is the total
number of experiments used for RR calculation. Fig. 4. Impacts of soil
properties including soil texture (a), soil organic carbon (SOC, b), C:N
ratio (c), and soil pH (d) on the response ratios (RR) of biochar
application on soil N2O emi­­­ssions. Number on the right side is the
total number of experiments used for RR calculation. Fig. 5. Impacts of
agricultural practices including biochar application rate (a), type of
fertilizer (b), and nitrogen (N) application rate (c) on the response
ratios (RR) of biochar application on soil N2O emi­­­ssion. Number on the
right side is the total number of experiments used for RR calculation.
