Abstract

The European Commission recognises the essential role of soil biology in soil functioning and deliveryof ecosystem services, but information is currently lacking evaluate of how these vary across soiland land-use types at a European scale. This study evaluated the measurement of the initial rate ofsoil basal respiration (BR) as a potential biological indicator of ecosystem service provision. The purposeof this study was to test ISO 16072:2002 (Soil Quality: Laboratory methods for the determiningof microbial soil respiration). In the literature a range of pre-incubation temperatures (pre-inc) andexperimental incubation temperatures (exp-inc) have been applied when using the ISO method forthe establishment of basal respiration. This study evaluated whether the range of temperatures appliedduring pre- and exp- incubation had a significant effect on the rate of respiration determined when followingthe protocol established in ISO 16072:2002. The evaluation was carried out on a pedo-climaticgradient spanning ten countries across Europe and covering four biogeographical regions. Three siteswere sampled in each country providing a range of soil and land-use parameters. Our results suggestthat experimental incubation temperatures of 20 ◦C or above should be used in the applicationof the methodology ISO 16072:2002 (incubation at 15 ◦C resulted in erratic variation between replicates).However, pre-incubation temperature did not affect the soil basal respiration rate, when followingthe standard recommendations. The time interval with the best prediction of the initial rate of basalrespiration was 6 h.
