Separating root and soil microbial contributions to soil respiration: a review of methods and observations
PJ Hanson, NT Edwards, CT Garten, JA Andrews - Biogeochemistry, 2000 - Springer
Forest soil respiration is the sum of heterotrophic (microbes, soil fauna) and autotrophic

Vegetation and soil respiration: correlations and controls
JW Raich, A Tufekciogul - Biogeochemistry, 2000 - Springer
Soil respiration rates vary significantly among major plant biomes, suggesting that
vegetation type influences the rate of soil respiration. However, correlations among climatic …
