Title : Factors causing temporal and spatial variation in heterotrophic and rhizospheric components of soil respiration in afforested organic soil croplands in Finland
Journal : Soil Biology & Biochemistry
Comment : Temporal variation in soil respiration was primarily related to changes in soil surface temperature (5 cm), which explained 71–96% of variation in soil respiration rates. Decomposition of peat and litter was not related to changes in water table level, whereas a minor increase in root respiration was observed with the increase in water table depth. Root respiration correlated positively with the biomass of ground vegetation. From the total soil respiration peat decomposition comprised a major share of 42%; the proportion of autotrophic respiration being 41% and aboveground litter 17%.
