TL;DR: In this paper, the authors reviewed several recently expressed concerns about uncertainties of chamber-based measurements of CO2 emissions from soils, and explained procedures that minimize these errors and biases, and provided procedures to minimize these uncertainties and biases.

TL;DR: In this article, the effect of soil moisture on chamber measurements was tested by wetting the fine quartz sand to about 25% volumetric water content, and the results showed that the chamber headspace concentration also affects the flux by altering the concentration gradient between the soil and the chamber.

TL;DR: In the second year, however, respiration in the fertilized hardwood plots was not different from the control plot as discussed by the authors, and the pine stand, annual soil respiration was 21 and 25% lower, respectively, in low and high N plots than the control plots.

TL;DR: In this article, the authors describe a unifying modeling framework to combine the effects of temperature, soil water content, and soluble substrate supply on decomposition of soluble soil-C substrates using simple functions based on process concepts.

TL;DR: In this paper, a field comparison of six individual systems for measuring soil-surface CO2 fluxes with each of the four basic system types represented is presented, and a single system is used as a reference and compared to each other systems individually in black spruce (Picea mariana), jack pine (Pinus banksiana), or aspen (Populus tremuloides) forests.
