Measurement conditions exert relatively small effects on measurements of soil respiration
What is it about?
"Soil respiration" refers to the movement of carbon dioxide (the product of respiration, for example when humans exhale) generated by plant roots and microbes from the soil to the atmosphere. This is a large and important flow of carbon in the earth system. In particular, scientists measure soil respiration under different conditions, but how these conditions affect their estimates is not well understood. This study used a synthesis of many different results from other published results to examine whether the conditions of measurements—i.e., choices made by individual researchers—affected their soil respiration estimates, and concluded that generally they did not.
Why is it important?
If estimates of soil respiration are biased for some reason, this could strongly affect our understanding of how the earth system operates. This study is the first to examine this problem for a very large number of published results globally.
